What gas do Chevy Vans take?
Most Chevy Vans run on regular unleaded gasoline, but heavier-duty models offer a diesel option as well. This article outlines the typical fuel choices across common van configurations and how to fuel them properly.
Fuel options for Chevy Vans
Chevy Express/Savana vans have historically been offered with gasoline engines and, in certain heavy-duty configurations, a diesel option. The following outlines the standard fuel requirements by engine type.
Gasoline engines
Gasoline-powered vans use conventional, regular unleaded fuel. Here are the common gasoline engine options and their general fuel recommendations:
- 4.3L V6 (gasoline) — Regular unleaded gasoline (87 octane) is typically recommended.
- 5.3L V8 (gasoline) — Regular unleaded gasoline (87 octane) is typically recommended.
- 6.0L V8 (gasoline) — Regular unleaded gasoline (87 octane) is typically recommended.
In all gasoline configurations, it’s best to follow the octane rating and fueling guidance printed in the owner’s manual for your specific model year and engine.
Diesel option
Some heavier-duty Chevy vans offer a diesel option powered by a Duramax engine. Diesel-powered vans require diesel fuel (ULSD). Here are the key points for the diesel configuration:
- 6.6L Duramax turbo-diesel V8 — Diesel fuel (ULSD, ultra-low sulfur diesel) is required. Always consult the owner’s manual for year-specific fuel requirements and recommendations.
Diesel engines are not compatible with gasoline. If your van has the Duramax diesel, use ULSD and follow maintenance guidance to keep the fuel system in good condition.
Fueling best practices
To ensure peak performance and reliability, always use the fuel type specified for your engine and adhere to the recommended octane level for gasoline engines. For diesel variants, use ULSD and follow the vehicle’s maintenance schedule to protect the fuel system and emissions equipment.
Summary
Chevy Vans primarily take regular unleaded gasoline for their common gasoline engines (4.3L V6, 5.3L V8, 6.0L V8). A diesel option is available on certain heavy-duty models, using ULSD diesel fuel with the 6.6L Duramax. Always verify the exact fuel requirements in your specific model year’s owner’s manual to ensure you’re using the correct fuel type and octane rating.
