The thing I find to be utterly amazing is the fact that so few people have changed their driving habits... Everyone is still stomping on the gas and brakes. (My first real job was one where I had to track my fuel expenses and fuel economy, so I've been in the habit all my life.) I drive a full size Dodge Ram pick-up. with a 318ci V-8 engine. My brother-in-law has the same truck. ('Cept fer the color...) When I bought it, I was getting about 11 mpg city and 14 or 15 on the highway. My average over the first years was right around 13 mpg. About three years ago, I decided I was going to change my driving habits to be as fuel efficient as possible. My BIL didn't believe it when I told him that my average went up to 19.6 mpg! But it did, and I proved it to him by using his truck for a week and got him 20.2 mpg. Here is how: 1 - I got my target max rpm by getting to highway speed. I saw that I could run at 65 mph at 2,000 rpm. (1,800 in the minivan.) 2 - I forced myself to try to never let it go above 2,000 (1,800 in the van) rpm when I was driving. Difficult, but do-able... Makes for slightly slower take-offs, but the gas savings is worth it! (Oh, and the people behind you can feel free to complain as soon as they are the ones putting the gas in my truck!) 3 - I always start the vehicle early enough so it is a normal operating temperature before I take it out of park. I might have used a pint of gas just idling, but compared to over a half gallon for the first mile with a cold engine was well worth it! A cold engine runs almost straight gasoline. There's barely any air going into the cylinders! 4 - In hilly terrain, I don't accelerate up hills. I build a little extra momentum up on the downhill run, and as soon as I start uphill, I lift off the gas a little. The goal here is to keep it from downshifting... Yes, it will slow down. but we are looking to save gas, right? (Same thing applies here with the people behind. They want to go faster, they are welcome to downshift, pass, and waste their own gasoline! They aren't buying mine, so they are not allowed to force me to waste it!) If you do this, I can guarantee a huge increase in your mileage! Oh yeah... you might need to leave 2 or three minutes earlier because of it! However, if you are not willing to change your driving habits, you will help keep the prices up, and you certainly have much less right to complain about it! The plan to have everybody stop driving for a day isn't really possible, but maybe getting everybody to drive wisely might actually work. Try it out and pass it along. Can you imagine what kind of impact it would have on the gas companies if every vehicle out there added 30 - 40% to their actual fuel mileage?
