Some horror stories there - worth noting! BP Ultimate all the way for me, been filling up the 2.0L turbo with it for 5+ years and whenever I swap to the Shell alternative I can literally hear the difference. Sounds like it's pinging or slapping, hard to believe I know.

Have decided to stick with the VZ cats for the IM240, will see how it goes on the 5 gas analyser tomorrow morning then off to VIPAC for the big one.
