how can i improve the fuel economy on my 2003 lexus rx300. I am getting 22 - 23 mph on non crowded flat
roadways. Otherwise 16 - 17 mph. i've seen forums where owners "modify" the horsepower or reprogram shift
points. I have tires inflated to 32psi and use full synthentic oil and have frequent front end alignments. I try to
drive with ecomony in mind. Had all transmission fluid changed at 95000 miles. Car runs like a dream
otherwise. Any recommendations?
A tune-up, oil and gas treatment, fuel system check and flush, drive slower. I like to use Sea Foam and drive slower.
