hmmm, i've always run my 5M-E on mobil and ampol premium unleaded. i was thinking of trying the LRP just to see how it would go.
which brings me to thinking that because we run premium unleaded in our cars.. should we be running a cat convertor? (mines not!)
it says in my car handbook that the 5M-E should be only run on 98octane Unleaded.. but its a pretty versitile engine and runs on just about anything but orange juice
i seem to get a fairly bad pinging sound when i run on regular unleaded too.
by the way.. when are the MA61's of South east queensland getting together? Jambouree is comming up isnt it?
