## What is E10 Fuel Compatibility Check?

Will your car or motorcycle run safely on E10? Get a clear answer in seconds — before you pull up to the pump.

E10 is gasoline blended with up to 10% ethanol, and it is replacing regular unleaded at more and more stations. Most modern engines handle it fine, but many older vehicles — especially carbureted ones — do not, and ethanol can slowly damage rubber seals and fuel lines. This app puts manufacturer recommendations for more than 1,200 car and motorcycle models across 80+ brands in your pocket, so you never have to guess.

WHAT YOU GET
- Instant E10 verdict for 1,200+ car and motorcycle models
- Three plain-language ratings: Compatible, Use with caution, Not compatible
- Practical advice for every result, not just a yes or no
- Fast search and filtering by vehicle type and brand
- A Saved list so your own vehicles are one tap away
- A Learn section covering what E10 is, why it matters, and common FAQs

PERFECT FOR
- Drivers unsure whether new E10 pumps are safe for their car
- Motorcycle and scooter owners protecting older engines
- Owners of classic or carbureted vehicles worried about ethanol
- Anyone who wants a quick second opinion before filling up

WHY NOT JUST SEARCH ONLINE?
Web results are scattered, contradictory, and rarely specific to your exact model. This app compiles the guidance into one consistent database with a clear rating and real advice — and it works fully offline, so you get your answer even at a remote station with no signal. No account, no sign-up.

PRIVACY
The entire vehicle database ships inside the app. There is no login, no tracking, and no collection of personal data. Your saved vehicles stay on your device.

FULL ACCESS
E10 Check is free to use. E10 Check Pro is an optional upgrade that supports development and unlocks unlimited lookups, unlimited saved vehicles, and the latest data updates:
