    It is 100% worth it for the power gains... they are huge! Cheapest bang for the buck for these cars by far. I have a station 2 minutes from my house, here in AZ we only have e54... I run a 50/50% mix to get e30... But I got to admit if I didn't have a station so close to me I don't know how worth the hassle of getting it would be. Check this page out for some tips on storing..... http://www.evolutionm.net/forums/e85...lon-drums.html

    What is the power gains from stock turbo full bolt on 93 to stock turbo full bolt on e30? It seems that 93 you will be around 210whp and e30 you're only at 220whp.

    I've run 4gallons of e85 + fill rest with 93

    I've done 5 gallons of e85 + fill up rest 93

    Same tune, same station I get e85 from, no noticeable difference.

    1 gallon of e85 is the difference between e40 and ~e37 (measured with my ethanol % gauge)

    It won't make a huge difference from what I can tell
    380whp 350wtq (e40)

    Peak numbers show like 10-15 more whp on e30 for me, but there is more power and torque across the entire rpm range. It really is a pretty good difference.

    Been running 93 now since it's winter here. I miss the extra power, but skinny squishy snow tires probably wouldn't like it lol.
