Two things decide whether Silverado maintenance parts are right: the specification stamped on your oil fill cap, and the oil life monitor on your dash. Neither is a mileage number. And the most common mistake is buying the oil that was correct for a 2015 truck and putting it in a 2022 one — GM changed both the specification and the viscosity along the way.

Stage 1: Day One, Before the First Service
Two things are worth doing before the truck has covered any real distance, because both get more expensive if you wait.
Floor protection. The first winter is what ruins a carpet, and salt that gets ground into the fibres does not come out. Buying liners after the damage is done protects nothing. Get the configuration right first — on 2019 and newer trucks, flooring material, first row seat type and second row under-seat storage all change the part.

Smart Trim Floor Liners — 2007–2013 Crew Cab
From $92.99. Also covers 2500/3500 HD crew cabs through 2014.
The Spare Key Argument Has Changed
Buying a spare fob early used to be about convenience. On modern trucks it is about cost, because replacement transmitters can no longer be programmed at home.
-
KEYECU 5-Button Smart Remote Key Fob — 2022–2024 Silverado / Sierra 1500
433 MHz, ID49 chip, FCC YG0G21TB2. Match the FCC ID and button count to your existing fob, and budget for programming by a dealer or automotive locksmith — on these trucks it is not an owner-performed procedure, and the programming can approach the cost of the part.
Get the quote for programming before you buy, not after. It sometimes changes which option makes sense.
Stage 2: Every Oil Change — Get the Specification Right
GM oils are sold against a specification, not just a viscosity, and the specification has moved.
dexos1 Gen 3 superseded dexos1 Gen 2. If you are buying oil for a current truck, Gen 3 is the current standard. Gen 2 remains on shelves and remains appropriate for older vehicles that call for it, but it is the older specification and buying it by habit is how people end up a generation behind.
ACDelco dexos1 Gen 3 Full Synthetic 5W-30 — 5 qt
From $58.95. Part 10-9330 / 19432322. The current specification in the traditional truck viscosity.
ACDelco dexos1 Gen 3 Full Synthetic 0W-20 — case of 6
From $58.99. Part 10-9322 / 19432331, listed for the 5.3L L82 and L84 and the 6.2L L87. This is the one most current Silverado V8 owners actually need.
5W-30 or 0W-20? Read the Cap
This is the correction that matters most on this page. An earlier version recommended a dexos1 Gen 2 5W-30 quart as the general Silverado oil. That is not right for every truck, and for a current one it is wrong twice over — wrong specification generation and wrong viscosity.
The modern 5.3L (L82, L84) and 6.2L (L87) V8s are specified for 0W-20. Older V8s were specified for 5W-30. Both oils are sold, both are legitimate, and putting the wrong one in is entirely avoidable because the required viscosity is printed on the oil fill cap under your hood.
Open the hood, read the cap, then buy. It takes ten seconds and removes the guesswork completely.
Diesel Is a Different Specification Entirely
If your Silverado has the 3.0L Duramax, none of the above applies. Light duty diesels use dexosD, which is its own specification.
-
ACDelco dexosD 0W-20 + PF66A Filter Bundle — 3.0L Duramax
From $112.99. Seven quarts of 10-9277 (19370138) plus one PF66A filter (19458926). Buying the oil and filter as a matched set removes the most common ordering error on the diesel.
The Oil Filter Is Engine-Specific, and There Is a Gotcha
Silverado oil filters are not one part. Which you need depends on the engine, and ACDelco catalogues them by number rather than by vehicle.
| Filter | GM number | From |
|---|---|---|
| PF63 | 12735811 | $12.29 |
| PF48 | 12737086 | $19.49 |
| PF2232 | 12691158 | $13.98 |
| PF2210 | 25313748 | $23.99 |
| PF627G (Gold) | 19346391 | $8.99 |
| PF2257G + cap seal | 55594651 | $11.49 |
The gotcha is PF2257G. It is listed for use with a cap marked HENGST — meaning that on some engines the correct cartridge depends on which supplier made the filter housing cap on your particular truck, not just on the engine. If your engine uses a cartridge filter in a screw-off housing, look at the cap before ordering.
-
ACDelco PF2257G Oil Filter and Cap Seal — 55594651
From $11.49. Includes the cap O-ring, which should be replaced with the cartridge rather than reused. Specifically for HENGST-marked caps. -
ACDelco PF63 Engine Oil Filter — 12735811
From $12.29. Also sold as a two-pack, which is worth it if you do your own changes.
Stage 3: The Monitor Decides, Not the Odometer
Modern Silverados use an oil life monitoring system. It is not a mileage countdown — it models how hard the engine has actually worked, factoring in things like operating temperature, engine revolutions and duty cycle. Two trucks with identical odometer readings can be at very different oil life percentages.
What that means practically:
- The 3,000 mile rule is obsolete on these trucks and running full synthetic to an arbitrary short interval mostly wastes oil.
- Heavy towing shortens the interval automatically, because the monitor sees the load. You do not need to guess at a severe-service schedule; the system already accounts for it.
- Reset the monitor after every change. An unreset monitor gives you no information at all on the next cycle, which is the most common way owners lose track.
- Time matters too. Oil degrades sitting still, so a low-mileage truck still needs changing on a calendar basis even if the monitor has barely moved.
Stage 4: The Fluids People Forget
Engine oil gets all the attention. These do not, and they are what quietly end transmissions.
-
ACDelco Dexron VI Automatic Transmission Fluid — 1 gal
From $41.99. Part 10-9395 / 88865602. Dexron VI is the GM automatic specification — do not substitute a generic multi-vehicle ATF on the basis that it says it covers Dexron. -
ACDelco Gold TF337 Transmission Filter Kit — 25325578
From $33.74. A fluid change without a filter is half a job. Verify fitment against your transmission before ordering. -
ACDelco 75W-90 Manual Transmission & Transfer Case Fluid — 1 qt
From $15.99. On a four-wheel-drive truck the transfer case is a separate service item from the transmission, and it is routinely skipped until it makes noise.
Stage 5: Brakes
Brakes are the wear item most likely to arrive earlier than expected on a truck that tows, because braking a loaded trailer is what actually consumes pads.
-
ACDelco Silver Front Brake Pad Set 14D369MX — GM 19286027
From $34.42. Semi-metallic. Covers a wide range of GM full-size applications — confirm yours is on the fitment list before ordering. -
ACDelco Silver Front Brake Rotor 18A925A — GM 19241877
From $57.54. Listed for Escalade, Silverado, Suburban, Tahoe, Sierra and Yukon — the shared full-size platform showing up again.
One diagnostic note worth carrying over from the drivability side: a caliper that drags does not always announce itself. Feel all four wheels after a drive. One noticeably hotter than the others means that corner is dragging, which eats pads, costs fuel and rarely sets a warning.
Stage 6: Later-Life Refresh and Repair
Past a certain age, the line between accessory and repair part blurs. The console lid and latch are the clearest example — they are known wear points, and they are sold as replacement parts against OEM numbers rather than requiring a whole console.
-
Center Console Latch — 2014–2020 (OEM 22792217 / 22861304)
From $63.84. If the lid no longer stays shut, this is usually the part. Two OEM numbers listed — match yours. -
GZJJMY Console Armrest Cover — 2019–2024
From $40.61. Protection if the armrest is still intact. If it is already split, replace rather than cover.
Stage Reference Table
| Stage | What to buy | What decides the part |
|---|---|---|
| Day one | Floor liners, spare key fob | Cab and interior configuration; FCC ID on the existing fob |
| Every oil service | Oil to spec, matching filter | Specification and viscosity on the fill cap; engine and filter cap marking |
| Interval driven by monitor | Oil, cabin and engine air filters | Oil life percentage, plus calendar time on low-mileage trucks |
| Mid-life | Dexron VI ATF and filter, transfer case fluid | Transmission type; four-wheel drive adds the transfer case |
| Wear driven | Brake pads and rotors | Actual wear, accelerated by towing |
| Later life | Console latch or lid, trim refresh | Whether the part is worn or merely dirty |
Prices are starting prices at time of writing and vary by pack size and availability. Confirm fitment against your VIN and engine before ordering.
What Other Pages Get Wrong
A correction to this page. An earlier version recommended a dexos1 Gen 2 5W-30 quart as the general Silverado oil. That is the older specification, and 5W-30 is the wrong viscosity for the current 5.3L and 6.2L V8s, which are specified for 0W-20. Both oils are still legitimately sold for the vehicles that call for them — the error was presenting one as universal. Read your fill cap.
"Change it every 3,000 miles." Carried over from an era before oil life monitoring and full synthetic. On a modern Silverado the monitor models actual engine work and is a far better guide than a fixed number.
"Any oil filter that screws on will do." Filter selection is engine-specific, and on cartridge-style housings it can even depend on which supplier made your filter cap. The PF2257G is listed specifically for HENGST-marked caps.
Treating a spare key fob as a convenience purchase. On 2022 and newer trucks the programming is not an owner procedure, and the labour is a real share of the total. That changes the maths on whether to buy ahead.
Skipping the transfer case. On a four-wheel-drive truck it is a separate service item with its own fluid, and it is the one most often ignored until it makes noise.
Frequently Asked Questions
What oil does my Silverado take?
Read the oil fill cap under the hood — the required viscosity is printed on it. Current 5.3L (L82, L84) and 6.2L (L87) V8s are specified for 0W-20; older V8s generally called for 5W-30. Then match the specification: dexos1 Gen 3 for current gasoline engines, dexosD for the 3.0L Duramax.
Is dexos1 Gen 2 still okay to use?
For vehicles that specify it, yes — it is still sold for exactly that reason. For a current truck, Gen 3 is the current specification. The mistake is buying Gen 2 by habit for a vehicle that calls for Gen 3.
Should I ignore the oil life monitor and change it every 3,000 miles?
No. The monitor models how hard the engine has actually worked rather than counting miles, so it automatically shortens the interval when you tow and extends it when you do not. Just reset it after every change, and still change on a calendar basis if the truck sits.
How do I know which oil filter I need?
Filter selection follows the engine, not the model year. If yours is a cartridge filter in a screw-off housing, also check the marking on the cap — at least one ACDelco cartridge is listed specifically for HENGST-marked caps and includes the cap seal.
Can I use generic multi-vehicle ATF?
GM automatics specify Dexron VI. A fluid marketed as covering multiple specifications is not the same as one built to that specification, and transmissions are an expensive place to economise.
When should I buy a spare key fob?
Before you need one. Match the FCC ID and button count to your existing fob, and get the programming quote first — on 2022 and newer trucks it requires dealer or locksmith equipment and can approach the price of the fob itself.
How do I know when brake pads need replacing?
Visual inspection at routine service is the reliable check. Squealing and reduced stopping performance are late signals. If you tow, expect pads to arrive earlier than the mileage suggests, and check all four wheels for heat after a drive — one hot corner means a dragging caliper eating that pad early.
