Consider driving at 65mph instead of +75 (which is considered slow here in CA). Also tail other cars like SUVs, trucks, and vans. Was watching Myth Busters the other day and you can increase your fuel efficiency by up to 35% depending how close you tail another car. I'm NOT saying you to follow 10 feet behind someone else, but instead of being the leader of every pack, consider being a follower instead. Even following 50 feet behind another car can reduce drag and save you ~5-10% on gas.

My drive up from LA to SF, I made it on one tank (400 miles) by tailing behind RVs and semis and going ~70mph. On the way down from SF to LA, I was rushing fast (+80mph) and I had to refill at 330. So yeah, it does make a big difference how fast you're going on the highway.

Plus I shift to neutral when going down steep hills (is this bad? idk ) and shift to neutral on red lights. It seems to help a tiny bit too. BTW, I'm on an auto 97 ST. Heh, doing this might not save me some gas, but it still makes me pick up more speed than simply coasting in gear...so idk

actually, your better off letting your foot off the gas, and coasting in gear.
anytime your above 1500rpm, in gear, and not on the gas, there is NO fuel being injected.
coasting in neutral down a hill or to a stop your wasting more fuel (because your using fuel at idle) than coasting in gear.

THANK U!!! i always use to shift in neutral too and thought i was saving gas.....

wow i didnt think it was the case but i did some googling and bam! it hit me source from popularmechanic q&a on a google search so it cant be wrong right? lol



Q: I have a question about fuel economy. If you are driving downhill, do you save gas by putting your transmission in Neutral and coasting, instead of having your vehicle in Drive? I think that you do but my wife seems to disagree. Can you give me the correct answer, so I can tell her that I’m “Mr. Right,” as usual?

A: That depends. The engine isn’t braking the car going downhill if the transmission is in Neutral, so economy would seem to be high. But if you think the engine is still using fuel while coasting downhill in gear, you’re laboring under a misconception. Most fuel-injected cars turn the fuel delivery completely off when you lift your foot from the accelerator. They still burn fuel when idling in Neutral, so do the math. The amount of fuel burned at idle over, say, a couple of miles of coasting downhill is small, but it’s still more than zero. So if you’re driving a modern fuel-injected car, you’re wrong.

Older, carbureted cars would suck gas through the engine while coasting in gear, even if you turned off the ignition switch. In this case you’d be right.
