CAN MY CAR RUN E85?

The fast checks: a yellow fuel cap, a Flex Fuel / E85 badge, or a sticker inside the fuel door all mean you're factory-ready. No badge? Look your car up below — it checks live EPA records for every US-market vehicle since 1984, engine by engine, because many models shipped both ways.

WHAT THE VERDICTS MEAN

• Factory flex-fuel — every version of the model is E85-ready. Fill up, or better, blend to a target.
• Flex-fuel on some engines — the model shipped both ways; match the engine badge below the verdict to what's under your hood.
• Not factory E85 — high blends need mods. The conversion guide covers exactly what and roughly how much.

FAQ

What if I put E85 in a non-flex car by accident?

One partial fill usually means a lean condition and a check-engine light, not a dead engine. Top off with gasoline to dilute it and drive normally. Don't make a habit of it.

My model shows flex-fuel but my engine badge says mods needed — which wins?

The engine. FFV packages were often tied to specific engines and trims — the door-jamb sticker and the eighth digit of your VIN settle it.
