I either use Texaco "High Octane" super unleaded (mainly because the garage is 30 seconds up the road) or Tesco 99 ron as stated above! I have been known to use the Sainsbury's Super unleaded because it's 88.9p at my nearest Sainsbury's, but it's like 10 miles away
2 of my mates run theirs on normal unleaded tho, but then they always seem to have problems
