I know this has been posted a hundred times before, but I am really worried about running optimax in my c20let as I have heard some bad things about it doing damage to engines. If it aint true i would like to run with it as it is 98 ron. I have been using it in my sri with the 8 valve engine since it came out and have had no problems.
Wether its true or not, its got me paranoid.
Is there anyone who actually knows if this is bad.........
