An E85 driver’s idea.
A community’s toolkit.
Built by an enthusiast to make flex-fuel ownership easier, more approachable, and more enjoyable.
The app I wanted at the pump.
I’m Julian F., the founder of 85Blends. My 2017 Dodge Charger R/T Scat Pack helped start this journey.
After beginning to modify the car, I made the switch to E85 with a flex-fuel kit. As I learned, I found myself searching for stations, using multiple calculators, and relying on advice from my cousin and other enthusiasts.
There were helpful tools, but none offered everything I personally wanted in one place. That inspired 85Blends: an app for blends, stations, fuel history, vehicle defaults, trip planning, and reminders.
“I built the app I wished existed when I first started running E85.”
Education is part of that mission. Flex-fuel ownership should feel less intimidating, whether you’re making your first approved ethanol fill or refining a performance build.

Encouragement that made a difference.
My cousin’s automotive journey helped inspire mine. His encouragement, and the early support of RVPSupply, helped turn the idea for 85Blends into an app for the community.
