Ok after reading the link posted by blue ghost I am now in two about what fuel to use lol I've allways used Ron 98 they only put ethanol in ron91 over here (thank Christ ) pritty sure I can still use 98 I am litteraly millimeters off having to use race fuel as my clearance is so close

do I even dare try Ron 95 to see if it doesn't valve slap :? Hahahhaha
