Alternative Fuels

We are certified in all hybrid, flex fuels and bio diesels. We will work on any type of fueled motor and fix it.


A hybrid vehicle uses at least 2 main power sources to operate the vehicle. Typically an internal combustion engine is paired with an electric motor.

Flex Fuels

Flexible fuel vehicles (FFVs) are manufactured to run on gasoline or a blend of up to 85% ethanol (E85). They are similar to gasoline-only cars, except for a few engine and fuel system modifications. When operating on E85, FFVs experience no loss in performance. However, ethanol contains less energy per volume than gasoline, therefore FFVs typically get about 25-30% less miles per gallon when using E85.

Bio Diesels

Bio Diesel vehicles uses diesel fuel made from vegetable oils, animal fats, or recycled grease. Bio Diesel is less pollutant and biodegradable.
