This was posted by "Dave 37" on saabcentral.com Its old info, but I find it interesting. Dont GM V8 cars skip gears for extra MPG? Here is the post: I read an article from the 1982 issue of Saab Soundings, the magazine published by Saab Scania of America which suggests trying the 1-3-5 method of shifting to save 10% fuel. The story has a picture of Olle Grandlund, noted as "in charge of engine testing at Trollhattan". They recommend driving a manual transmission car to 1500-2000 rpm then shifting from 1st to 3rd, flooring the accelerator, and repeat the same procedure jumping from 3rd gear to 5th gear. They explain that this reducing the pumping loss. With a small throttle opening, the engine has to work to pump air in. This wasted energy is reduced when the throttle is wide open. It says that you can save up to 10% in fuel this way. The current 9-3 owner's manual cautions not to drive with a wide open throttle during the break-in period of (?) 3000 mi (or was it the first 1200 mi). Opinions on lugging an engine?
