I Decided to do a rough fuel economy test with my car just to give an idea to those that have been tinkering with the idea of switching over to e85 in the Z33/v35 platform.
Pros:
Octane rating of 104-110
Power Bump (+4 whp)
$2 a gallon
Specialty Parking in flex fuel spots
Cons:
Having to locate e85 stations
Having to drive conservatively or you'll see 9-11 mpg's
People constantly confronting about how you're not supposed to pump diesel in your car.
