As I understood it he claims to get 80mpg with e-85 and could get up to 100mpg with gas.

His story hasn't really been proven as i'm sure he wants to keep any secrets he might have in place till after the 10million dollar challenge.

A few people on another forum claim to know the guy and they all are claim he is full of shit. Said his shop doesn't even have running water and is very low budget. I'm not sure as anything is possible.
