Is it ok to pop my Celica into neutral and coast a half mile here and there?
I've been doing it lately but I've heard you are not supposed to do that with some automatic trans cars.
BTW - on a recent tank with highway driving and some coasting and other "hypermiling" driving techniques, I squeaked out 40 mpg, beating my old record by 2.5 mpg. Oh, I also pumped the tires to 42
