What would happen if you put E85 in a REGULAR engine?

Would it damage anything? A REGULAR engine is one that isn't truly equipped for this grade.

    E85 is very corrosive. Engines that can tolerate it have their fuel system made of material that can tolerate alcohol without corroding. Some car makers even warn against using E85. It's a very poor fuel anyway, with low energy content and much more is needed to do the same work real gasoline would do. GM and Ford made their effort to adapt to it and promote it, but some of the damage done was to drive up food costs.

    It might damage the seals and parts in fuel injectors because of the high alcohol content. The fuel is designed for E85/flex fuel automobiles. It shouldn't be a problem if you have used it once or twice, but you will damage a car designed to run on normal octane fuel.
