we have 92 and 95 in Trinidad but the price for 95 recently shot through the roof so everyone is contemplating going with 92. Mind you, our quality of gas has been skeptical and 92 may very well not be 92 but something a bit lower.
My question is, is it safe for the R18 with a 10.5 : 1 ratio to run 92/91 grade gasoline? Does anyone else currently do this with no pinging even under load?
