Whats the deal with Maxol E5 fuel?

[A80Avant]

yes. but the bottom line is to get the gas in, put a pair of headphones to the knock sensor and listen.Otherwise you cannot judge how the car 'feels'. It may have been colder or hotter day.

my only concern is the fact that E5 i on regular and regular is 95 rating. Can only 5% of ethanol take it to 99 octane or more?

Tesco 99 = rocket fuel, I've been saying that for ages because I could feel it but didn't know why... now I do

Does the ethanol cause any illeffects in the fule system like perishing the rubber seals or owt?

When you want to find pages and pages of nonsense you search using google

However when you want actual information you search the s2 forum. Legendary stuff Mark, and they sell this E5 stuff 6 miles from my house.
