[QUOTE="wkmac, post: 88463, member: 2189"] Also learn to use what we call "Georgia Overdrive" and that is on large hills put it in neutral and let it roll while the engine RPM's at idle. Some argue that just taking your foot off the gas is enough but if you have a tach, look at engine RPM's in both cases. When just taking your foot off the accelrator it takes some time for the engine RPM to start dropping in relation to the speed of the car. In neutral, the RPM's go immediately to idel speed (around 700 rpms) and therefore you've just dropped your volumetric cylinder intake because the number of intake cycles just dramatically dropped with it. Learn to momentum drive very much like the NASCAR guys do on restrictor plates tracks and I've actually gotten another day of going back and forth to work out of a tank of fuel doing this. It also helps that I work evening so my commutes are off hours and especially coming home I'm generally a very lonely driver. This helps a lot. Also if your tires call for 32 psi go to 35 psi and get more rollout per revolution. In other words cover more distance for the same amount of energy used. If you like cutting it close on your speed with the traffic cop be careful because it can bite you too. [/QUOTE]
