What gas does a Chevy 2500 take?
The Chevy Silverado 2500HD can be powered by either gasoline or diesel—gas engines take regular unleaded gasoline (87 octane minimum) and the Duramax diesel option uses ULSD diesel.
Two fuel configurations exist for the Silverado 2500HD. Gasoline variants use standard gasoline, while the Duramax diesel requires diesel fuel and uses DEF for emissions control. The exact grade and requirements vary by model year, so consult the owner's manual for your truck's specific guidance.
Gasoline-powered Silverado 2500HD
For gasoline-powered Silverado 2500HD models, fueling is straightforward. Here is a quick guide to the fuel you should use.
- Fuel type: Regular unleaded gasoline (87 octane minimum).
- Octane guidance: 87 octane is standard; higher octane is not typically required unless your manual specifies it for a special configuration or towing scenario.
- Fuel quality: Use fuel from reputable stations and follow the owner's manual for any regional recommendations or restrictions.
Gasoline variants of the Silverado 2500HD typically run on regular 87-octane gasoline; premium fuel is not generally required for normal operation.
Diesel-powered Silverado 2500HD (Duramax)
Diesel-powered Silverado 2500HD models use diesel fuel and incorporate emissions-control systems that rely on Diesel Exhaust Fluid. Here are the essentials for this configuration.
- Fuel type: Ultra-low sulfur diesel (ULSD).
- DEF: Diesel Exhaust Fluid (DEF) is required for emissions control; monitor and refill as directed by the vehicle’s gauge or owner’s manual.
- Biodiesel compatibility: Some Duramax engines may be compatible with certain biodiesel blends (such as B20) depending on year and configuration; always verify year-specific guidance in the manual or with a dealer.
In practice, use ULSD with DEF for diesel-powered Silverado 2500HDs and follow year-specific recommendations for biodiesel compatibility and maintenance intervals as outlined in the owner's manual.
Summary
Bottom line: The Chevrolet Silverado 2500HD offers both gasoline and diesel options. Gas engines take regular unleaded gasoline (87 octane minimum), while Duramax diesel engines require ULSD and use DEF for emissions control.
