Ive been driving for 33 years and logged many hundreds of thousands of miles. Driving style has lots to do with mpg, ( speaking as a life long "lead foot" I KNOW what I am talking about). Use cruise control all you can, take off with in "reason", slow down gradually when you are going to have to stop. These things help a little, but the majority of difference comes from a well tuned engine. I have an MK4 NA getting 30+ MPG and my last car was a 5 speed 1jz MK3 getting 30,I have had 3 7MGTE cars getting 25+. Id rather have something like this than a 35 ( if you are lucky) 4 cylinder which you have to catch on a down hill slide to pass anyone. The Supras I read about on here getting 15 or so need a serious "diagnosis" to what the problem is. Best advice for higher MPG, slow down enjoy the ride!!!
