What kind of gas do you put in a van?
The fuel you use depends on your van’s engine. Most consumer vans run on gasoline or diesel, and a growing number options include alternative fuels or electric power. Always use the fuel type and grade specified by the manufacturer to avoid damage.
In practice, check your specific model’s manual and fuel-cap label to confirm which fuel is approved. Gasoline engines require unleaded petrol with the recommended octane rating; diesel engines require ultra-low sulfur diesel (ULSD) unless the manufacturer allows a specific biodiesel blend. Some fleets are built to use compressed natural gas (CNG), liquefied petroleum gas (LPG), or other alternatives, and electric vans use charging instead of traditional fuels. This article explains how to identify the correct fuel for your van and how to refuel properly.
Identify your van’s fuel type
Confirming the correct fuel type for your van helps prevent misfueling and potential engine damage. Use these checks to be sure.
Common fuel types for vans
Vans are powered by a range of propulsion options. The most common are gasoline and diesel, with some models offering alternative fuels or electric power.
Gasoline engines
Gasoline-powered vans burn unleaded petrol. Use the octane rating recommended by the manufacturer; many modern vans run fine on 87 octane, while some engines may require higher-octane fuel (91–93). In many regions, gasoline is commonly available as E10 (gasoline with up to 10% ethanol), and only flex-fuel models should use higher ethanol blends if specified by the manufacturer.
Diesel engines
Diesel vans typically use Ultra-Low Sulfur Diesel (ULSD). Always use the diesel type specified by the engine and avoid any mixes that aren’t approved by the manufacturer. Some vans can tolerate biodiesel blends (for example, B20) if the manufacturer confirms compatibility; otherwise, stick with ULSD. Misfueling a diesel engine with gasoline can cause severe damage, so if misfueling occurs, do not start the engine and contact a service professional.
Alternative fuels
Some vans are designed for alternative fuels such as compressed natural gas (CNG), liquefied petroleum gas (LPG, propane autogas), or biodiesel blends in diesel platforms. These options require dedicated fueling infrastructure, tanks, and engine calibrations, and are not universally available. Electric vans do not use gasoline or diesel and must be charged from an appropriate electrical supply.
Key steps to verify the right fuel before you fill up:
- Check the owner’s manual or the fuel door label for the required fuel type and any octane or blend specifications.
- Inspect the engine type or VIN in the vehicle documents or on the dashboard to confirm gasoline vs diesel.
- Look for labeling near the fuel cap that clearly states “Gasoline” or “Diesel” and follow those instructions.
- If you’re unsure, ask a dealership or qualified mechanic before refueling; using the wrong fuel can cause costly damage.
- Always use the grade (octane) and fuel type recommended by the manufacturer; for diesel, use ULSD unless a specific blend is approved.
Following these steps helps prevent misfueling and protects the engine and fuel system.
Additional considerations for non-standard vans:
- Vans designed for CNG, LNG, or LPG require dedicated fueling stations and tanks; never refuel with gasoline or diesel in these systems unless the manufacturer explicitly approves it.
- Electric vans are charged rather than refueled with combustion fuels; use appropriate charging infrastructure and avoid attempting to fill with fuel.
- If your van supports biodiesel, confirm compatibility with the engine and fuel system and adhere to the recommended biodiesel blend limits.
In all cases, verify fuel compatibility with your vehicle’s documentation and the fueling station’s available options.
Summary
Most vans run on either gasoline or diesel, with alternatives and electric options available for certain models. Always use the fuel type and grade specified by the manufacturer, and be aware of regional standards (such as ULSD for diesel in many markets and typical octane recommendations for gasoline). If in doubt, consult the owner’s manual or a qualified technician to prevent misfueling and potential damage.
