Ok guys, heres a link to a picture of my 4 new NGK plugs that i pulled after 1000 miles, they look too clean and the 4th plug (can't see it on here) had some molten greenish substance burned onto the earthing electrode...i am using castrols valvemaster lead replacement as its an engine that the owners manual, and the haynes manual state that 98 RON 4 star petrol is to be used as its a 10.1 compression petrol engine and not every fuel station gives it octane rating it just says 'premium'..but that means bugger all to me haha
Too lean, or too clean?... -
