Ahh Holden, I remember the good old days when if you let the 202/3.3l motor ping without correcting it, you could very likely lose the top off one or more pistons. Happened to me and took some time before I could see the street through the massive clouds of oil smoke. Meanwhile, what pressure do you run your tyres at? Adding 5 or more psi will improve economy but say goodbye to the armchair ride. I run my 195x55x15 razor blades at 36 round town and 40psi on highway and get excellent economy. Of course, I look after all the other relevant things like plugs, leads, filters and correct fuel for the car.
