How Long Do Silverados Last? 5.3L vs 6.2L vs Duramax

Short answer: a well-maintained Chevy Silverado lasts 200,000 to 300,000 miles. The engine you picked at the dealer matters more than anything else, and the gap between the best and worst Silverado powertrains is bigger than most owners realize.

Duramax: 300k+ miles 5.3L V8: ~220k miles 6.2L V8: 200-250k Avoid 2007-2014 AFM

The Verdict

Silverados last 200,000 to 300,000 miles with routine maintenance. How long do Silverados last in practice? The 5.3L EcoTec3 V8 averages around 220,000 miles, the 6.2L V8 lands between 200,000 and 250,000 depending on year, and the 6.6L Duramax diesel routinely pushes past 300,000 miles. The trucks themselves (frames, body mounts, axles) outlast the engines by a wide margin.

The Silverado's reputation for going the distance is well-earned, but it is not automatic. Skip oil changes, ignore lifter ticks, or buy the wrong model year and you can be looking at a $4,000 engine repair by 120,000 miles. Do it right, and 250,000 is the floor.

The Numbers: Lifespan by Engine

Not every Silverado is built the same. Here is what real-world data and owner reports show across the most common engine options from 2007 to 2025:

EngineYearsAvg LifespanCommon Failure Point
5.3L Vortec (LMG/LH6)2007-2013180-220kAFM lifters, oil consumption
5.3L EcoTec3 (L83)2014-2018200-240kAFM lifter failure ~120k
5.3L EcoTec3 (L84)2019-2024220-260kDFM lifters, AFM Lifter Disabler can extend
6.0L Vortec (LY6)2007-2019 HD250-300kSpark plugs, water pump
6.2L V8 (L86/L87)2014-2024200-250k2019-2021 lifter recall, valvetrain

3.0L Duramax (LM2)2020-2024TBD, ~250k est.Too new for confirmed data

The takeaway: if longevity is your top priority, an L5P Duramax HD is almost unbeatable. If you want the gas value play, a 6.0L from a 2500HD is the dark horse, often outlasting the popular 5.3L by 50,000 miles.

When a Silverado Makes Sense (And When It Does Not)

Buy a Silverado if:

  • You can find a 2019+ 5.3L with the AFM/DFM disabler installed, or a model from 2025+ where GM dropped the cylinder deactivation hardware.
  • You want a heavy-duty diesel and can afford the $8,000 to $12,000 premium for the Duramax option (it pays back in resale and lifespan).
  • You are buying a 6.0L 2500HD with under 150,000 miles. These are slept-on workhorses.
  • You actually tow or haul. The 6.2L gas V8 with the 10-speed is the best gas tow rig in its class.

Skip the Silverado if:

  • You are looking at a 2007-2018 5.3L with no documented lifter or AFM work. Walk away or budget $3,500 for the inevitable.
  • You need a 2019-2021 6.2L without proof of the P0300 lifter recall work being completed.
  • You are buying purely as a commuter. The 22 MPG ceiling is brutal compared to a half-ton hybrid.

Common Mistakes That Cut Silverado Lifespan in Half

The Silverados that die at 150,000 miles almost always have one of these stories behind them:

  1. Ignoring the AFM ticking sound. That faint ticking at idle on a 5.3L? It is a collapsed lifter. Wait six months and it eats the camshaft. Repair goes from $1,800 to $4,000. See our engine ticking guide for what to listen for.
  2. Skipping transmission fluid changes. The 6L80, 8L90, and 10L80 transmissions need fluid changes every 45,000 miles, not "lifetime fluid." Skip it and the torque converter clutch shudders, then dies around 130,000.
  3. Cheap oil on a diesel. The Duramax needs full-synthetic 15W-40 (CK-4 or newer). Conventional oil shortens injector and turbo life by 30 to 40 percent.
  4. Letting the rear diff run dry. Especially on tow-package trucks, the rear differential needs fluid every 50,000 miles. Owners forget, and pinion bearings go around 180,000.
  5. Never replacing the fuel pump. On GMT900 and K2XX platforms, the in-tank fuel pump fails around 150,000 miles. Replace it preventively and you save the towing bill plus a stranded weekend.

Decision Framework: Which Silverado for Which Owner

Not sure which model year or engine to chase? Match yourself to one of these buckets:

Whichever route you go, run a pre-purchase inspection and pull live data on the engine. A $50 OBD scan tells you more about a used Silverado than any Carfax report. Our used truck inspection guide walks through the exact codes to check.

Cost of Ownership Past 200k Miles

Crossing 200,000 miles in a Silverado does not mean the truck is on its last legs. It means your annual repair bill steps up from "almost nothing" to "a few real items per year." Here is what to budget:

  • Water pump: $500-700 installed, typically around 150-180k.
  • Fuel pump assembly: $700-900, often at 150k.
  • AC compressor: $900-1,200, usually 180-220k.
  • Transmission service: $250-350 every 45k miles.
  • Front suspension (control arms, ball joints): $1,500-2,200 around 180k.
  • Lifter replacement (if AFM): $2,500-4,000, typically 120-160k.

Even with these line items, the all-in cost per year usually lands at $1,500 to $3,000, which is still cheaper than a $700-per-month new truck payment. The Silverado wins on total cost of ownership precisely because the powertrain hangs in there for so long.

Frequently Asked Questions

How long do Silverados last in miles?
A well-maintained Chevy Silverado typically lasts 200,000 to 250,000 miles. Duramax diesel models routinely push past 300,000 miles, while the gas 5.3L V8 averages around 220,000 miles before major engine work.
Which Silverado engine lasts the longest?
The 6.6L Duramax diesel is the longevity champion, with many owners reporting 300,000 to 500,000 miles. Among gas options, the 6.0L Vortec from older HD models is the most durable, often outlasting the 5.3L by 50,000 miles.
What years of Silverado should I avoid?
Avoid 2007-2014 5.3L models with Active Fuel Management for oil consumption issues, and 2019-2021 6.2L trucks with lifter failures. The 2014-2018 5.3L EcoTec3 had the AFM problem extended, costing owners around $4,000 to repair.
Is a Silverado more reliable than an F-150?
They are close. The Silverado 5.3L tends to have fewer transmission complaints than the F-150 EcoBoost, but the F-150's 5.0L Coyote V8 matches or exceeds the 5.3L in longevity. Diesel-to-diesel, the Duramax beats the F-250 Power Stroke on long-term reliability.
How much does it cost to keep a Silverado running past 200k miles?
Expect $1,500 to $3,000 per year in maintenance and repairs after 200,000 miles. Common high-mileage items include water pump ($600), fuel pump ($800), transmission service ($300), and lifter replacement on AFM engines ($2,500 to $4,000).

Bottom Line

So, how long do Silverados last? Plan on 200,000 to 250,000 miles from a gas 5.3L or 6.2L with average care, and 300,000-plus from a Duramax that gets clean fluids and timely service. The trucks themselves easily go further. What kills most Silverados early is ignored AFM lifter ticks, skipped transmission services, and cheap fuel pumps that should have been replaced at 150,000.

If you are buying used, focus on the model year and engine combo, not just the mileage. A 280,000-mile L5P Duramax with documented service is a better long-term bet than a 90,000-mile 2017 5.3L with no maintenance records. Use the engine table above as your filter, then run the truck through a real diagnostic before you sign.
