Quick primer: Most U.S. rentals run on regular unleaded (87 octane). Some models require premium (91–93), while others use diesel or, rarely, E85 (flex‑fuel only). Check the fuel door sticker, cap, or dashboard, and match the pump label exactly.
Regular vs. premium—what’s the difference?
Regular (87) is common and safe for most engines designed for it. Premium (91–93) is for engines that specifically require higher octane; using it in a regular‑fuel car won’t add power or mileage. Follow the car’s requirement—don’t guess.
What about E85 and diesel?
E85 is a high‑ethanol blend for flex‑fuel vehicles. Never put E85 in a non‑flex‑fuel car. Diesel pumps and nozzles are usually clearly marked; if you selected a diesel class, double‑check before fueling.
Five renter‑proof steps at the pump
- Confirm the fuel type in the vehicle and on the rental agreement.
- Choose the correct grade on the pump and take a photo of the selection.
- Keep the receipt and photograph it—some counters request proof to waive refueling fees.
- Top up within 10 miles/15 km of return and note the station address on the receipt.
- If you misfuel, don’t start the engine. Call roadside support immediately.
