    I have an older Ford Mustang and it gets great gas mileage, I would presume it is the fuel injection, my other ford got good gas mileage just the same it also had fuel injection but was a smaller engine, I also drive smoothly and time those lights and use my exhilerator to slow down the car before getting to the stop light instead of the brake, driving defensively helps too.

    well about if car makers will make more clean diesel ! wnd why by SUV to go grocery store and taking kids to school ! and please give me a break don't even go there try to justify you need more room to carry bicycles and toys !! what is that ?? can your kids play at home i have two kids and i don't carry any of that. i have down sized from honda pilot to mini cooper, I'm on my second mini!! and i still think its a lot for fueling up $50 when Full Empty!! and I blame on all those that (need to drive Big Engine Vehicles) I will love to drive one too but not until their MPG will get better!!!

    Dillion, Your car gets better mileage when it is low on oil, because the crankshaft is spining in a pan of oil and the oil causes alot of drag or friction to the spinning crankshaft. When your car is low on oil the oil level in the oilpan is so low that it is not touching the rotating crankshaft, thus alowing it to spin without the drag or friction from the oil in the oilpan. (Parasitic drag) Many cars have a sheet metal tray surrounding the crankshaft (windidge tray) that stops the oil from touching the rotating crankshaft when your vehicle is accelerating or decelerating. The oil in the engine tends to move around like a wave in the ocean when you accelerate and decelarate, this is the reason that a windige tray was designed. If you run your car 1 quart lower than the recommended full line on your dipstick your mileage will increase and your engine will not suffer from lack of oil. If you run your car 3 quarts lower than the full line on your dipstick, then you risk the chance of running your oil pump dry and ruining your engine bearings and seizing your engine. Good luck and good observation noticing the mileage gain from low oil levels.

    Most of these are very good tips for saving fuel. It may be impossible for most of us to avoid driving during peak traffic hours, as a majority of us commute to our jobs during peak hours. Try leaving earlier? Maybe, depending on how much sleep you want to lose to save some fuel? I would not recommend driving in the far right lane for any length of time, as merging traffic is always entering and leaving the freeway from this lane, which will cause you to constantly change speed, which also wastes fuel. You are better off choosing the middle lanes and staying at a constant speed with the flow of traffic.

    I own a 97 Camry that is slowly leaking motor oil for a couple of years. Somehow, when the engine oil was at the "low" level, I got incredible gas mileage(~30mpg) drving around DFW local area. I am wondering if anybody ever notices the same phenomenon or has a scientific expanantion on this?

    @Scott, Your experience does go along, somewhat, with what I've observed over hundreds of test vehicles. Vehicles with smaller engines see more significant improvements from changes in driving style than those with big V-8s.
    And @JKD, you're right about coasting in Drive, not Neutral; I've had engineers confirm this.

    I drove a 2005 Dakota 4X4 for four years. 99% of miles were in town. I averaged 10.9 MPG no matter how I drove. I tried every one of those tips and more, including over-inflating the tires, shutting it off every time I had to stop for more than a few seconds, removing unnecessary items(weight) and driving with the tailgate down. I also tried driving like a maniac, flooring the accelerator at every takeoff, driving clear up to a stop and slamming on the brakes, running with the windows down and the air on and nothing made even a tenth of a mile per gallon difference.

    That's because you owned a Dodge, Dodge gets the worst gas mileage, so no matter what you do it's pointless to try to save gas.

  • Racer1 Posted: 3/21/2011 6:31am PDT

    Oddly, nothing was said about the time spent sitting and idling while waiting for morning coffee or meals in drive through queues. Park it and go inside. Idling an engine in a drive through adds 0 mpg for 3-5 minutes each time this is done.

    At least you stay to the right - kudos to you! On trips under 60 miles 55 may be ok, but on many returns with the family from Boston to Detroit it would cost over $160 to slow down from 70 -75 mph to 55 mph. I may put another $20 -30 of gas into the Chrysler T&C to go faster, but 55 means an overnight stay and extra meals vs a non-stop run at 75. Time is money, and when you're hauling 3 kids it's worth alot! Especially since we are only looking at going up to 26 / 27 mph from 22 / 23 mph.
    As for everyday driving, at the minutes long lights in Mass I have turned my car into a hybrid by turning off the engine for the 90 - 120 seconds we idle, and that makes a real difference.

    @jdl50cc - All of your tips are good except for one that gives you up as an oldtimer :-) Throwing the tranny into neutral on fuel injected cars will actually use more fuel (just like idling your engine) than just taking your foot off the gas and leaving it in drive (this uses ZERO gas.)

  • jdl50cc Posted: 3/19/2011 12:46pm PDT

    "[R]eal tips for real drivers?" Sure. I'm a "real driver" and I consistently get better fuel economy than others driving the same model vehicle, and I'm not one of those potentially dangerous hyper-milers. On the highway, just slow down. Set the cruise and park yourself in the rightmost lane. Get a book on tape or CD to keep your focus. If you calculate how much later you will arrive, you'll be surprised how small the difference is unless you're driving much further than you are. If you drive on surface streets, then drive as though you have no brakes. If you see a red light, then take your foot off the gas and maybe even throw the tranny into neutral (which isn't actually legal). You may be surprised how many lights are timed on major thoroughfares, but it doesn't work if you don't look far ahead of you and anticipate. It becomes sub-conscious after a while.

    I drive over 100 miles every day. Do you have any real tips for real drivers?

  • JKD Posted: 3/19/2011 5:34am PDT

    I wish 55 came back and/or the speed limits were enforced better. Most of ATL inside of 285 is limited to 55 but if you don't go 75-85 MPH then you're a road hazard even in the slow lane where the trucks try to run you over... Last time I saw a cop was four years ago when he pulled me over in my GTO commuting back from the bus station out of all places... I don't understand the lack of enforcement in GA - it's a goldmine for cash-strapped budgets but no one cares.

    Thanks for the insight. I will think about it when I am on the road.
