Not that an extra couple of bucks per tankful will break me, but I just read an article by M. Niedermayer in "Truth about cars" stating among other things, that using regular gas instead of premium in a high compression (11 to 1) engine would not affect performance or mileage by more than a percent or two. He went on about not changing your oil, but perhaps only once a year, as today's oils and today's engine are tuned to avoid sludge formation and crankcase contamination, but that is another story. I just would like to send out a feeler to see if any of you folks have had good or bad experiences with using regular versus premium gas in your Lexus'... I just hate enriching gas purveyors unnecessarily.......
