I run E85 (85% ethanol) in every car I can convert, it's a great fuel. However, we also install fuel cut-off switches in all those cars too (and anything made before ~1980) as well as install new gas caps and thoroughly test the tanks. That way if they have to sit for longer than a couple days, we can close off the fuel line and prevent possible fume seepage and lessen evaporation. Most new cars are fairly flex-fuel ready, with a few modest changes, while others are 100% ready from the factory, like the Koenigsegg and 12C. The former makes even more horsepower while running it (980hp on pump gas > 1150hp on E85 > 1185hp on E100). The system just knows and adjusts timings and compression automatically. It's some kind of Swedish witchcraft. BTW, we have found that car's Kryptonite, so to speak (aside from eating tires), apparently the normal replacement interval for its clutch is 30k kms
. I'm not going to say how much they are... but if a person were paying parts and labor, it would be about the same as a whole new Subaru BRZ. Fortunately, I just have to pay for the part, which is only a little more than a new Kia Soul.
No, I'm not bragging at all, just an interesting bit of maintenance trivia. Oh, and there's the differential @50k kms, heads @60k, complete engine rebuild @80k, etc. etc...
BTW, we may potentially become an official service center for Koenigsegg, not that it would generate much business (there are only 15 or so in the USA), but the only other one in North America is in Nevada. They're supposed to get back with my manager about the requirements.Edited by Magick Man - 10/19/13 at 9:31am
