Chevrolet S10 Oil Capacity & Oil Type
TL;DR
2.8L Duramax (LWN): about 5.7 L / 6.0 US qt with filter, 5W-30 dexos2. 2.5L Flex (L4T): about 5.0 L / 5.3 US qt with filter, 0W-20 dexos1 Gen2. Always check your owner's manual or oil filler cap for your exact build.
Chevrolet S10 (Brazil/Latin-American market) oil capacity by engine
The Chevrolet S10 sold in Brazil and across Latin America has used several engine families over the years, and oil capacity is tied to the specific engine code, not just the model name or displacement. This page covers the two engines with the most consistent data across service sources: the 2.8L Duramax turbodiesel (code LWN) and the 2.5L Flex gasoline/ethanol engine (code L4T). Where we could not confirm a precise figure for an older engine, we say so rather than guess.
2.8L Duramax turbodiesel (LWN)
This inline-4 turbodiesel has been the mainstay diesel engine in the modern Brazilian-built S10 (used through the 2012-2016 facelift generation and continuing, with updates, in later generations). Service data lists the oil capacity with a new filter at approximately 5.7 liters (6.0 US quarts), using SAE 5W-30 oil meeting the GM dexos2 diesel specification.
2.5L Flex (L4T)
The 2.5L 16V flex-fuel four-cylinder (engine code L4T), used in the S10 gasoline/ethanol lineup, takes approximately 5.0 liters (5.3 US quarts) with filter, specified as SAE 0W-20 meeting GM dexos1 Gen2.
Older 2.4L Flexpower engine
Earlier S10 trucks (roughly 2012-2016) offered a 2.4L Flexpower four-cylinder. Sources for this engine's exact capacity with filter are inconsistent (figures from about 4.3 L to 5.0 L appear depending on the source), so we are not stating a single number here. GM literature generally points to SAE 5W-30 dexos1 oil for this engine; confirm your exact capacity using the methods below before topping off.
Always confirm on your own vehicle
Oil capacity and viscosity can change between model years, markets, and even trim levels sharing the same displacement. Before any oil change, verify using your specific truck:
- The oil specification label under the hood or on the oil filler cap
- Your owner's manual maintenance/capacities section, matched to your VIN and engine code
- A dealer or trusted mechanic who can look up your exact build by VIN
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 2.8L Duramax turbodiesel (LWN), Brazil-market S10 | 5.7 L / 6.0 qt | 5W-30 (dexos2) |
| 2.5L Flex (L4T) | 5.0 L / 5.3 qt | 0W-20 (dexos1 Gen2) |
| 2.4L Flexpower (approx. 2012-2016) | Not consistently confirmed (approx. 4.3-5.0 L reported); check owner's manual | 5W-30 (dexos1) per GM guidance |

Frequently asked questions
Does the S10's oil capacity depend on the engine or just the model?
It depends on the specific engine code, not the model name. The Brazil-market S10 has used at least three different engine families (2.4L Flexpower, 2.5L Flex L4T, and 2.8L Duramax LWN), and each has its own oil capacity and viscosity requirement, so match the figure to your engine code, not just to 'S10'.
How much oil does the 2.8L Duramax S10 take with a filter?
Service data for the 2.8L Duramax turbodiesel (engine code LWN) lists approximately 5.7 liters (6.0 US quarts) with a new filter, using SAE 5W-30 oil meeting the GM dexos2 specification. Confirm on your dipstick after refilling since small variations exist between model years.
What viscosity does the 2.5L Flex S10 need?
The 2.5L 16V Flex engine (code L4T) specifies SAE 0W-20 oil meeting GM dexos1 Gen2, with a fill capacity of about 5.0 liters (5.3 US quarts) including the filter.
Where can I find the exact oil capacity for my specific S10?
Check the oil specification sticker under the hood or on the oil filler cap, look up the maintenance section of your owner's manual using your engine code, or ask a dealer to pull the exact specification for your VIN, since capacity and viscosity vary by model year and engine.
