what kind of gas does my car take

Most cars clearly state the correct fuel type near the fuel filler door and in the owner’s manual, and you should always follow exactly what is printed there for your specific vehicle. Using the wrong fuel (like diesel in a gasoline car, or lower octane than required) can damage the engine or emissions system, so when in doubt, check the manual or ask a dealer before pumping.

Where to look on your car

• Inside the fuel door there is often a label that says something like “Unleaded gasoline only,” “Diesel fuel only,” or even a specific octane such as “Premium unleaded only 91+.”

• The gas cap itself may be printed with the required fuel type or octane rating.

• The instrument cluster or fuel gauge area sometimes shows a fuel symbol or wording indicating the fuel type on newer vehicles.

Owner’s manual and paperwork

• Your owner’s manual has a fuel or “Specifications” section that lists the exact fuel type (gasoline vs diesel, octane rating, ethanol limits such as “up to E10” or “E85 only,” etc.).

• Registration documents or online lookups using your VIN or plate (through manufacturer or third‑party “fuel type check” tools) can also confirm whether the car is gasoline, diesel, flex‑fuel, or something else.

Gasoline grades and octane

• At a gasoline pump, grades are usually “Regular,” “Midgrade,” and “Premium,” which correspond to increasing octane numbers (for example 87, 89, 91–93 in many regions).

• If your manual says “regular unleaded” and lists something like “minimum 87 octane,” you do not need premium, though you can use it without harm; if it says “premium required,” using regular can cause knocking and long‑term engine issues.

Gasoline vs diesel and other fuels

• A diesel vehicle must only be filled with diesel; putting gasoline in a diesel can damage the injection system and fuel pump, while diesel in a gas car typically causes stalling and may require the tank to be drained.

• Some vehicles are labeled flex‑fuel and can use higher‑ethanol blends like E85, but non‑flex‑fuel gasoline cars should stick to the ethanol percentage stated in the manual (commonly “up to E10”).

If you still aren’t sure

• Look up your exact year, make, and model on the manufacturer’s website or a trusted auto site, and verify the fuel section matches what you see on your fuel door label.

• If labels are missing or confusing, call a dealer’s service department with your VIN; they can tell you the correct fuel in a few seconds, which is far safer than guessing at the pump.

Bottom line: always use the fuel type and octane printed on your fuel door and in your owner’s manual; if you tell the year, make, and model, it becomes possible to look up more specific guidance.
