[86 South Africa]

So I wanted to ask some knowledgeable guys a few things;
We know ethanol helps with "cooling", can be used to get more power and has some benefits over normal petrol/gas.

1) if it has a cooling effect then would it naturally help engine longevity? E.g. Same car driven under same conditions for 50,000km on e85 should (all else being equal) last better than a car on normal gas?
Is that a fair comment?

2) apart from higher fuel consumption & possible water issues (if you leave the car standing) what downsides are there to ethanol?

3) if no.1 is true, would it be magnified for FI applications? So under an assumption that added power doesn't damage the engine parts, e85 is better than normal fuel for boosted cars?

I'm not looking for heavily scientific answers... just summarised versions :-)

Cheers,
