Used GM 2.7L TurboMax Review for Silverado and Sierra Buyers in Brockville
This used GM 2.7L TurboMax review starts with the honest answer: one can be a very good half-ton work truck, and it can be the wrong truck entirely. The difference is not the badge on the tailgate.
Model year, configuration, maintenance history, how hard it was towed, what the inspection finds and what the VIN history shows all decide it, and every one of those belongs to the individual truck rather than to the engine.
It is written for the owner who works a truck around Leeds and Grenville, and it goes in that order: what the engine is, which years to shop, what to check, and what it will and will not do.
We are Brockville Ford on Eleanor Street, a Ford store that also appraises, inspects and retails used trucks of every make, Silverado and Sierra trades included.
Get the looking done before the first cold snap, while a trailer still hitches in daylight and the concession roads are dry.
Key Takeaways
The 2.7L TurboMax is the turbocharged four-cylinder built for the Chevrolet Silverado 1500 and GMC Sierra 1500 half-tons. The TurboMax name is published on the current 2026 material, so this guide calls the earlier trucks the 2.7L turbocharged four-cylinder.
A 2.7L four-cylinder Silverado 1500 and Sierra 1500 is listed in the Government of Canada's fuel consumption ratings for every model year from 2019 through 2026, in two-wheel and four-wheel drive, with no gap.
Horsepower, torque and towing are not published today for a 2022, 2023, 2024 or 2025 truck, so this guide states none of them for those years. What a specific truck is set up to do is read off the truck, and we go through its own label and the equipment actually fitted with you before you buy.
When we searched the federal recall database on September 24, 2026, not one notice listed for the 2022 to 2025 Silverado and Sierra half-tons was scoped to the 2.7L engine, and no notice at all was listed for the 2025 Silverado or the 2025 Sierra.
Shortlist by configuration and history rather than by badge, and start with the used trucks we carry.
Quick Answer From This Used GM 2.7L TurboMax Review
Buy one when the truck itself checks out: continuous service records, a clean cold start, no stored codes, a sound turbo and cooling system, and a hitch and wiring that match the way it was used.
Choose something else when none of that can be shown to you, or when your week is closer to daily heavy towing than to a loaded trailer a few times.
Six things settle it, and the badge is not one of them:
The model year and the exact configuration: cab, box, drive, axle and the equipment actually fitted.
The maintenance history, and whether it runs continuously or in gaps.
How the truck was towed, and how often.
What a pre-purchase inspection finds under the hood and underneath.
What the VIN history and the recall record show.
What you actually tow and carry, loaded rather than empty.
A used half-ton arrives with whatever the first owner ordered rather than whatever the brochure said, so read the truck rather than the badge, and do the same when you scan our used inventory.
What the GM 2.7L TurboMax Is
The 2.7L TurboMax is the turbocharged four-cylinder engine built for GM's half-ton pickups, the Chevrolet Silverado 1500 and the GMC Sierra 1500. It is a four-cylinder in a full-size truck, which is exactly why working owners ask whether it is enough engine.
Turbocharged means the engine uses its own exhaust flow to push extra air in, so a smaller engine can make more power than its size suggests.
Torque is the pulling effort you feel when a loaded trailer starts moving. Horsepower is what keeps it moving once you are up to speed on the 401.
One point of honesty about the name. TurboMax is the name published on the current 2026 Silverado 1500 and Sierra 1500 material, and it is what people search, so it sits in the title of this guide.
For a 2022 to 2025 truck we call it the 2.7L turbocharged four-cylinder, because the manufacturer publishes the current model year only and what it was called in those years is not something we can confirm today.
In the same government listing, every 2.7L four-cylinder Silverado 1500 and Sierra 1500 from 2019 through 2026 runs an eight-speed automatic.
Half-ton is the old shorthand for a full-size pickup in this class, the Silverado 1500, Sierra 1500 and F-150 size, and it says nothing on its own about what any one truck is rated to carry.
When you are ready to shop rather than read, start with the used trucks we carry, which lists every make we retail rather than Fords alone.
Which Used Model Years to Shop
Shop the years the way the record actually supports them. A 2.7L four-cylinder Silverado 1500 and Sierra 1500 appears in the Government of Canada's fuel consumption ratings for every model year from 2019 through 2026, in both two-wheel and four-wheel drive, so no year in the used window is missing the engine.
What is missing is the manufacturer's own figures for those years, and the gap is a large one rather than a detail:
Model year | Rated for sale in Canada with the 2.7L four-cylinder, as the Government of Canada lists it | Transmission | Official fuel consumption rating | Engine name, horsepower, torque and towing published for that year |
|---|---|---|---|---|
2022 | Yes, two-wheel and four-wheel drive | Eight-speed automatic | Published | Not published today for that model year |
2023 | Yes, two-wheel and four-wheel drive | Eight-speed automatic | Published | Not published today for that model year |
2024 | Yes, two-wheel and four-wheel drive | Eight-speed automatic | Published | Not published today for that model year |
2025 | Yes, two-wheel and four-wheel drive | Eight-speed automatic | Published | Not published today for that model year |
2026 | Yes, two-wheel and four-wheel drive | Eight-speed automatic | Published | Published, under the TurboMax name |
The manufacturer publishes the current model year only, so the horsepower, torque and towing figures for a 2022, 2023, 2024 or 2025 truck are not on any page we can read today, and they are not ours to invent.
That is why this used GM 2.7L TurboMax review carries empty cells instead of confident numbers.
The answer is on the truck rather than on a page. Our service team on Eleanor Street goes through the truck's own label and the equipment actually fitted with you, before you buy, and that is what tells you what it is set up to do.
So shortlist by configuration and by history, and let the model year be the last thing you argue about.
Reliability on a Used GM 2.7L TurboMax
Reliability on a used half-ton is decided by the truck in front of you, not by the engine family. No manufacturer or government source publishes a fault record for this engine, so this guide names no common problems, and nobody selling you a truck should either.
There is plenty of opinion about this engine online, and we have read the same threads you have. None of it is published by anyone who has to stand behind it, so none of it is in here.
What we do instead is look, and this is the list we work through on a high-kilometre half-ton of any make:
Service records: continuous or patchy, who did the work, and whether anything was deferred.
Cold-start behaviour: how it sounds and idles from properly cold, not after somebody has warmed it up for you.
Stored and pending diagnostic codes on a scan tool, including codes that were cleared recently.
The turbocharger and the boost system: charge piping, clamps, hoses, the intercooler, and oil traces where there should be none.
The cooling system: level and condition, the hoses and the cap, and any sign of a leak or a past overheat.
The transmission cold, warm, in gear, and under load with a trailer behind it.
Evidence of heavy towing: hitch and ball wear, the wiring and its connector, brake-controller wiring, and how the rear suspension and brakes look next to the odometer reading.
Four-wheel-drive engagement in each mode, and how the transfer case behaves.
Frame, underbody, brake and fuel lines, bed mounts and body seams, which is the salt check on any truck that has worked four winters in Leeds and Grenville.
Tires, brakes, and the vehicle's own label in the driver's door jamb, read with you standing there.
None of that is a list of faults in this engine. It is the list any working truck earns after four winters, and a truck either passes it or it does not.
High-kilometre work trucks of every make share the same wear points, and our guide to electrical problems on a high-kilometre F-150 shows the kind of checking we mean.
Recalls and VIN History on a Used Silverado or Sierra
A recall is a repair the manufacturer has asked dealers to make, not a verdict on a truck.
When we searched Transport Canada's recall database on September 24, 2026, not one notice listed for the 2022 to 2025 Silverado and Sierra half-tons was scoped to the 2.7L engine, and no notice at all was listed for the 2025 Silverado or the 2025 Sierra on the day we searched.
Notices can be added after any search, so we check for open recalls as part of our used-vehicle inspection, and we will show you how to check any VIN on the manufacturer's own recall lookup: book the truck in and we will go through it with you.
A GM recall repair itself is done at a GM dealer.
Towing and Payload, Read the Exact Truck Rather Than the Advertisement
What a used half-ton can pull and carry is a property of that individual truck, set by its engine, cab, box, drive, axle and the equipment fitted to it, and reduced by everything you then put in it.
No towing figure is published today for a 2022 to 2025 Silverado or Sierra with this engine, so this guide states none for those years.
Payload for this engine is not published at all, on either side of the comparison below, so no payload number appears in this guide for the GM trucks or for the F-150.
Weigh the work before you shop the truck:
What the trailer weighs loaded, with the implement or the equipment on the deck, rather than empty.
What goes in the box at the same time: fuel, fencing, feed, tools, a pallet of seed.
The hitch, the wiring and the brake controller that trailer needs.
The people in the cab, because they come off the same number.
The surfaces you pull on most, from a soft field entrance to the 401 on-ramp at Mallorytown.
Ontario's own driver's handbook sets the trailer rules you have to meet whatever you tow with:
A trailer at 1,360 kg gross weight or more must have brakes strong enough to stop and hold it.
Safety chains are crossed under the tongue, with latching hooks.
The hitch is matched to the trailer's gross weight, with the ball level and not tilting.
Five to ten per cent of the trailer's total weight sits on the hitch.
The trailer carries a white licence plate light, a red tail light and two red rear reflectors.
Our commercial vehicle team does this arithmetic with farm and contractor customers, and the conversation is worth more before you buy than after.
What that particular truck is set up to do is written on the truck and built into the equipment on it, so we go through both with you before you buy.
GM 2.7L TurboMax vs F-150 2.7L EcoBoost
Model year 2026 is the only year both manufacturers publish today, so it is the only like-for-like figure comparison this guide can make honestly.
On those 2026 figures the GM engine leads on torque and on the published tow rating, and the Ford engine leads on horsepower and on the official fuel ratings.
For 2026 the GMC Sierra 1500 with the TurboMax is published at 310 horsepower, 430 lb.-ft. of standard torque and available max towing of up to 4,309 kg (9,500 lbs.), which means as that truck is equipped, and it is standard on the Pro, SLE and Elevation trims.
The same 430 lb.-ft. of standard torque is published for the 2026 Chevrolet Silverado 1500 with that engine, paired with an eight-speed automatic.
For 2026 the Ford F-150 with the 2.7L EcoBoost is published at 325 horsepower, 400 lb-ft of torque and an 8,400 lbs max available tow rating, again depending on how the truck is equipped, and the same government listing puts it on a ten-speed automatic with select shift.
Those are 2026 trucks. A used 2022 to 2025 Silverado, Sierra or F-150 is not rated by any of those numbers, and a 2026 tow rating never tells you what a used truck will pull.
Line | GM's 2.7L turbocharged four-cylinder in the Silverado 1500 and Sierra 1500, named TurboMax for 2026 | Ford's 2.7L EcoBoost in the F-150 |
|---|---|---|
Engine layout as the Government of Canada lists it | Four-cylinder | Six-cylinder |
Transmission for 2026 | Eight-speed automatic | Ten-speed automatic with select shift |
Where it leads on the published 2026 figures | Torque and the published tow rating | Horsepower |
Combined fuel consumption, 2022 through 2026, in litres per hundred kilometres, where lower is better | Uses more fuel in every year, in both drivetrains | Uses less fuel in every year, in both drivetrains |
What settles it on a used truck | The individual truck, its history and its inspection | The individual truck, its history and its inspection |
The fuel numbers behind that fourth row are in the next section.
If you would rather start new than shop a used half-ton, the Ford side of this comparison sits in our new Ford inventory.
Fuel Use and Ownership Cost
The Government of Canada rates the 2.7L F-150 lower on combined fuel than either 2.7L GM half-ton in every model year from 2022 through 2026, in two-wheel drive and in four-wheel drive.
Four-wheel drive is the set a working owner around here orders, so that is the set below, and both GM trucks are listed beside the F-150.
Combined ratings in four-wheel drive, in litres per 100 km, as the Government of Canada publishes them:
2022: Silverado 4WD 13.1, Sierra 4WD 13.1, F-150 4X4 11.7.
2023: Silverado 4WD 12.2, Sierra 4WD 12.4, F-150 4X4 11.5.
2024: Silverado 4WD 12.3, Sierra 4WD 12.9, F-150 4X4 11.8.
2025: Silverado 4WD 12.9, Sierra 4WD 13.5, F-150 4X4 11.8.
2026: Silverado 4WD 12.8, Sierra 4WD 13.6, F-150 4X4 11.8.
In two-wheel drive the same pattern holds. The Government of Canada's official ratings put both GM trucks at 11.6 L/100 km combined for 2022 and 12.5 for 2025, against 10.9 and 11.3 for the F-150 in those two years.
A rating belongs to the configuration as it was tested, not to a truck with four winters and high kilometres on it, a load in the box and a trailer behind it.
Fuel is one line on a farm or fleet ledger and it is rarely the biggest. Tires, brakes, routine service and downtime move the total more over a season, and a truck standing still costs more than a truck that drinks.
Tires do the stopping and the steering once the truck is loaded, and our winter tire package is the simple way to get a set on before the first snow.
Our guide to the F-150 oil change interval on a work truck shows what routine service looks like on a vehicle that works for a living.
Who Should Buy a Used GM 2.7L TurboMax and Who Should Choose Something Else
It suits a farm or trade owner who pulls a loaded trailer a few times a week rather than all day every day, runs real distance between jobs, and buys on condition and records rather than on the badge.
Choose differently when the work is daily heavy towing near the top of a half-ton's range, when you want a V8 for reasons of your own, or when the job has outgrown a half-ton altogether.
Where the choice usually lands:
Farm and trade work with a trailer a few times a week: a good fit, provided the records and the inspection are clean.
Light towing and a lot of running around the county: the case a four-cylinder turbo was built for, and the fuel ratings above are the line where it trails an F-150 least on paper.
Daily heavy towing near the limit: decided by the ratings on that exact truck, and a used truck with a hard towing history behind it is the one to walk away from.
Set on a V8: fair enough, and the same rule applies, because the manufacturer publishes the current model year only and the used-year figures are not published for any of its engines either.
Cross-shopping an F-150: the only like-for-like published comparison is model year 2026, and it is in the section above.
Work that has outgrown a half-ton: that is a three-quarter-ton conversation, and our commercial and Super Duty inventory is where it starts.
Less truck than a half-ton: our Ford Ranger buyer's guide for work trucks covers the size down.
Brockville Ford Used-Truck Inspection and Trade-In Process
Every used truck we retail is inspected before it is delivered, whatever badge is on the tailgate.
The order is simple: you tell us what the truck has to do, we drive it loaded rather than empty, we put it on a hoist, and then we sit down with what we found.
Our service department on Eleanor Street does the inspection and the road test, and the technician who drove it is the one who tells you what it needs.
We read the truck's own label and walk the equipment actually fitted with you in the same visit, so you leave knowing what you are buying.
Ontario's own description of a safety standards certificate is worth knowing. It confirms the vehicle met the minimum safety standards on the date the certificate was issued, and it is not a warranty or guarantee of the vehicle's condition.
That is exactly why a used truck still gets looked at properly, and why we go through the findings with you rather than handing you a sheet.
A registered dealer in Ontario must also disclose a long list of things in writing:
Total distance driven, and any odometer that is broken, replaced, rolled back or reading in miles.
Previous use as a daily rental, as a police or emergency services vehicle, or as a taxi.
Fire damage.
Flood damage or liquid reaching the interior floorboards.
Structural damage or structural repair.
A total-loss declaration.
Registration outside the province.
A salvage, rebuilt or irreparable classification.
Recovery after a theft report.
A private seller owes you a used vehicle information package and nothing else, and that is the practical difference between the two ways to buy a used truck.
Trading the truck you are working now is how this usually ends, paid off or not: see what your current truck is worth online, then bring it to Eleanor Street with its service records and any lender payout details.
A work truck is judged on how it was kept as much as on the odometer, so bring the paperwork for the hitch, the tires and the service that was done.
Financing a used work truck is available O.A.C., and you can start our online credit application from the shop office before you make the drive in.
If you are weighing a private sale against a trade, our guide on how to sell a car in Ontario walks through the bill of sale and the paperwork.
Frequently Asked Questions
Is the GM 2.7L TurboMax reliable used
No manufacturer or government source publishes a reliability record for this engine, so we make no claim about how it holds up, and nobody selling you one should either. There is plenty of opinion online and we have read the same threads you have, and none of it is published by anyone who has to stand behind it.
What the record does show is that when we searched the federal recall database on September 24, 2026, not one notice listed for the 2022 to 2025 Silverado and Sierra half-tons was scoped to the 2.7L engine.
Reliability on a used truck is settled by that truck's service history, what the inspection finds and how hard it was towed, which is what a pre-purchase inspection is for.
What can a used Silverado or Sierra 2.7L TurboMax tow
No towing figure is published today for a 2022 to 2025 Silverado or Sierra with this engine, so nobody can honestly quote you one for a used truck of those years. The rating belongs to the exact truck as it was built and equipped, and we go through that truck's own label and the equipment fitted to it with you before you buy.
For reference, the 2026 GMC Sierra 1500 with the TurboMax is published at available max towing of up to 4,309 kg (9,500 lbs.), which means as that truck is equipped. That figure belongs to a 2026 truck and not to a used one.
Are the Silverado and Sierra 2.7L engines the same
On the current 2026 material it is the same engine, sold under the TurboMax name in both the Chevrolet Silverado 1500 and the GMC Sierra 1500, and published at the same 430 lb.-ft. of standard torque in both.
The Government of Canada still rates the two trucks separately, and they are not always identical: for 2024 the Silverado 4WD is rated at 12.3 L/100 km combined and the Sierra 4WD at 12.9.
On a used truck, the equipment fitted to the individual vehicle matters more than the brand on the grille.
Which model years use the 2.7L TurboMax
A 2.7L four-cylinder Chevrolet Silverado 1500 and GMC Sierra 1500 is listed in the Government of Canada's fuel consumption ratings for every model year from 2019 through 2026, in two-wheel and four-wheel drive, with no gap.
The TurboMax name itself is published on the current 2026 material. What the engine was called in 2022, 2023, 2024 and 2025 is not something we can confirm today, so this guide calls it the 2.7L turbocharged four-cylinder for those years.
Should I buy a used 2.7L TurboMax, 5.3L V8 or F-150 2.7L EcoBoost
Model year 2026 is the only year both manufacturers publish today. On those figures the GMC Sierra 1500 with the TurboMax is published at 310 horsepower and 430 lb.-ft. of standard torque, and the Ford F-150 with the 2.7L EcoBoost at 325 horsepower and 400 lb-ft of torque.
On fuel, the Government of Canada rates the 2025 Silverado 4WD at 12.9 L/100 km combined, the 2025 Sierra 4WD at 13.5 and the 2025 F-150 4X4 at 11.8, and the F-150 is rated lower in every year from 2022 through 2026.
No output or towing figure is published today for a used-year GM V8, so that side of the choice cannot be made on numbers at all. Choose on what you tow, what the inspection finds and what the records show.
What should I inspect before buying a used GM 2.7L truck
Read the service records first and look for continuity rather than volume. Then start the engine properly cold, scan for stored and pending codes, look over the turbo plumbing, the intercooler and the cooling system, work the four-wheel drive through each mode, and check the hitch, the trailer wiring and the rear suspension against the odometer reading.
Underneath, the salt check matters in this county: frame, brake and fuel lines, bed mounts and body seams on anything that has worked four winters in Leeds and Grenville.
Then drive it the way you will use it, loaded, down a gravel concession road and out onto the 401. Book the inspection online and our technician will do all of it with you.
