Chevy Silverado Oil Capacity Chart by Year and Engine 1999-2026
Chevy Silverado oil capacity ranges from 6 quarts up to 10 quarts, and the number that matters is tied to your exact engine, not just the displacement on the fender badge. The biggest source of confusion is the 5.3L V8.
A 2010 Silverado with the Vortec 5.3L takes 6 quarts, while a 2015 Silverado with the EcoTec3 5.3L takes 8 quarts, even though both trucks say “5.3L” on the same spot.
This chart covers every Silverado engine from the 1999 Vortec lineup through the current EcoTec3, TurboMax, and Duramax family. Use your engine’s RPO code below to find your exact fill spec, then read on for the reason the numbers changed and what oil type each engine actually needs.

The 5.3L EcoTec3 briefly shipped as 8.5 quarts on 2014 and 2015 owner’s manuals before General Motors corrected the official specification to 8.0 quarts. More on that correction below.

Here is how to confirm which row applies to your specific truck.
How to Identify Your Silverado Engine Code
Your engine’s RPO code is the only reliable way to match your truck to the correct row above. Two Silverados with the same displacement badge can need a different amount of oil.
- Open the glovebox and check the inside of the door or the label on the box itself. GM often lists RPO codes there.
- Check the door jamb sticker on the driver’s side door frame, which lists a full RPO code block.
- Cross-reference the code against the chart. A code starting with L8 or L3 points to a newer EcoTec3 or TurboMax engine. A code starting with LM, LY, LQ, or LR points to an older Vortec engine.
- If you still cannot find the code, best years for Chevrolet Silverado 1500 models breaks down which generation and engine combinations were offered by year.
Once you know your engine, the next question is why the numbers jumped so much in 2014.
Why the 2014 EcoTec3 Switch Changed Oil Capacity
The 2014 EcoTec3 5.3L and 6.2L V8s use a deeper oil pan than the Vortec engines they replaced. GM redesigned the pan and baffle system to support direct injection, variable valve timing, and cylinder deactivation, all of which draw on oil pressure differently than the older engines.
That redesign is the real reason capacity jumped from 6 quarts to 8 quarts, not a simple engineering preference. The added volume keeps oil pressure stable while those systems cycle.
GM’s own service bulletin confirms the number wasn’t settled immediately. Early 2014 and 2015 owner’s manuals listed 8.5 quarts, but GM’s technical service bulletin PIP5231A corrected that figure to 8.0 quarts after dealers reported the dipstick reading overfilled.
If you own a 2014 or 2015 Silverado and your paperwork says 8.5 quarts, treat 8.0 quarts as the current spec. Chevy Silverado transmission issues from the same 2014 to 2015 window are also worth a look, covered in the 2015 Silverado 1500 transmission recall details.
Getting the quantity right matters, but the oil type has to match too.
Which Oil Type Each Silverado Engine Requires
Oil viscosity changes almost as often as capacity across Silverado generations. Using the wrong viscosity does not just waste money. It affects cold start protection and can reduce fuel economy on newer engines tuned for thinner oil.
- Vortec-era engines (1999 to 2013), all displacements: SAE 5W-30
- EcoTec3 gas V8s built 2014 through 2018: SAE 5W-30
- EcoTec3 gas V8s built 2019 and newer: SAE 0W-20 meeting the dexos1 specification
- 2.7L Turbo I4: SAE 5W-30 dexos1
- 3.0L Duramax inline six diesel: dexosD 0W-20, which is not interchangeable with standard dexos1
- 6.6L Duramax V8 diesel (HD trucks): 15W-40
If you’re deciding between conventional and full synthetic for an older Vortec engine, Pennzoil Platinum versus Ultra Platinum breaks down the difference in a way that applies directly to these fill specs.
One more variable affects your total oil purchase: the filter.
Oil Filter and Drain Plug Torque by Silverado Engine
The filter you use changes how much oil actually fits, since a fresh filter holds a partial quart on its own. Match your filter to your engine family, not just your truck’s model year.
- Vortec-era engines (4.3L, 4.8L, 5.3L, 6.0L, 1999 to 2013): ACDelco PF48
- EcoTec3 gas V8s and V6 (2014 and newer): ACDelco PF63
- 2.7L Turbo I4 and 3.0L Duramax I6: ACDelco PF66
- 6.6L Duramax V8 diesel (L5P, 2017 and newer): ACDelco PF63, revised to PF63B on 2024 and newer trucks
Drain plug torque on most gas V8 Silverados runs around 18 ft-lb. Overtightening strips the pan threads, so a torque wrench is worth the ten extra minutes. While you’re under the truck, checking lug nut torque specs for the Chevy Silverado 1500 is a natural add-on to the same maintenance session.
A few specific questions come up often enough to answer directly.
Frequently Asked Questions
How much oil does a 5.3L Silverado take?
It depends on the generation. A 1999 to 2013 Vortec 5.3L takes 6.0 quarts with a filter, while a 2014 and newer EcoTec3 5.3L takes 8.0 quarts.
Did Chevy change the 5.3L oil capacity in 2014?
Yes. GM increased the 5.3L capacity from 6.0 quarts to 8.0 quarts starting with the 2014 EcoTec3 redesign, which used a deeper oil pan to support new engine systems.
What oil does a 2019 or newer Silverado 1500 need?
Most 2019 and newer gas V8 Silverados need SAE 0W-20 meeting the dexos1 specification. The 2.7L Turbo I4 uses 5W-30 dexos1 instead.
How much oil does a Duramax Silverado hold?
The 3.0L Duramax inline six diesel holds 7.0 quarts of dexosD 0W-20. The heavier 6.6L Duramax V8 diesel in HD trucks holds 10.0 quarts of 15W-40.
Can I use 0W-20 in an older Vortec 5.3L Silverado?
No. Older Vortec 5.3L engines built through 2013 are specified for 5W-30, and GM does not list 0W-20 as an approved alternative for that generation.
Getting Your Silverado Oil Change Right the First Time
Getting Chevy Silverado oil capacity right comes down to one habit: checking the RPO code before you buy anything, not just the engine displacement. The 2014 EcoTec3 split is the single detail that trips up more owners than anything else in this chart.
Buy the exact quart count and viscosity for your engine, install the matching ACDelco filter, and torque the drain plug to spec. Then check the dipstick after the engine has run for a minute and settled. The chart gets you close, but the dipstick always has the final word.
