82 xjs regular gas?
Hey all. I just bought a sales brochure for my 82 and where it described the "new" HE head design, the article states, and I quote. " This enables the engine to run on a leaner mixture and a higher compression using regular unleaded fuel". So, if I understand that properly then I've been wasting money by using premium all these years. Or, am I missing something somewhere in that statement? Does anyone have info on this. I'd love to save some money. Thanks. Bud
