How can you improve gas mileage?
Here are some tips for improving your gas mileage.
Drive slower. The faster you drive, the more fuel you use. For example, driving at 65 miles per hour (mph), rather than 55 mph, increases fuel consumption by 20 percent. Driving at 75 mph, rather than 65 mph, increases fuel consumption by another 25 percent.
Use overdrive gears. Overdrive gears improve the fuel economy of your car during highway driving. Your car's engine speed decreases when you use overdrive. This reduces both fuel consumption and engine wear.
Use cruise control. Using cruise control on highway trips can help you maintain a constant speed and, in most cases, reduce your fuel consumption.
Anticipate driving situations. If you anticipate traffic conditions and don't tailgate, you can avoid unnecessary braking and acceleration, and improve your fuel economy by 5 to 10 percent. In city driving, nearly 50 percent of the energy needed to power your car goes to acceleration. Go easy on the gas pedal and brakes. "Jack-rabbit" starts and sudden stops are wasteful.
Avoid unnecessary idling. Turn off the engine if you anticipate a lengthy wait. No matter how efficient your car is, unnecessary idling wastes fuel, costs you money and pollutes the air.
Do more in a single car trip. Several short trips taken from a cold start can use twice as much fuel as one trip covering the same distance when the engine is warm.
Remove excess weight from the trunk. Avoid carrying unneeded items, especially heavy ones. An extra 100 pounds in the trunk reduces a typical car's fuel economy by one to two percent.
Keep your engine tuned. Studies have shown that a poorly tuned engine can increase fuel consumption by as much as 10 to 20 percent depending on a car's condition. Follow the recommended maintenance schedule in your owner's manual; you'll save fuel and your car will run better and last longer.
Keep your tires properly inflated and aligned. Car manufacturers must place a label in the car stating the correct tire pressure. The label usually is on the edge of the door or door jamb, in the glove box, or on the inside of the gas cap cover. If the label lists a psi (pounds per square inch) range, use the higher number to maximize your fuel efficiency. Underinflated tires cause fuel consumption to increase by six percent.
Change your oil. Clean oil reduces wear caused by friction between moving parts and removes harmful substances from the engine. Change your oil as recommended by the vehicle manufacturer.
Check and replace air filters regularly. Your car's air filter keeps impurities in the air from damaging internal engine components. Not only will replacing a dirty air filter improve your fuel economy, it also will protect your engine. Clogged filters can cause up to a 10 percent increase in fuel consumption.

Truthfully, there isn't much you can do to get a great improvement, but you can change your air filter, make sure your tires have the correct pressure, clean out your intake, …turn off the a/c, and just plain don't drive it hard. Avoid jerky starts, take your foot off the gas and coast as far as you can up to stoplights, don't accelerate hard, etc. Also, if you do a lot of highway driving, try setting your cruise control at 5mph slower, you may be surprised. In my car, theres a 4mpg difference between 70 and 75 mph. Don't feel like you're alone, the gas prices are killing all of us!

Well it all really comes back to one thing, you can't punch it all of the time I know that might seem hard not to do but it's the only way that you can get "Good" gas mileage.… Make sure that you keep the Transmission setting in the "Economy" mode (Represented by an "E" on the dash display). Keep the transmission from shifting at more than 2000 RPM. Use the cruise control a good majority of the time. Keep tire pressure at around 37 PSI. Modify the air in take with either a K&N or a Stainless Steel Spectre air filter. Make a "Make shift" heat shield, to block manifold heat out of the air intake. You can use the bottom half of the stock air box. Avoid unnecessary up shifts (i.e. going up hill). Keep the car running at tip top shape. Hope that this will help you!
High performance exhausts can have a small, yet statistically insignificant, impact on fuel efficiency. They tend to be installed for a differenct exhaust sound or improved po…wer, not improved fuel mileage.
There are two visual experiments that answers this: . 1) No. There was a recent episode of Mythbusters that tried it. Gas mileage was actually reduced by 30%.. 2) Yes. This… has been tested by a user on MetaCafe and proven in his eyes to work. There is a lot of speculations as to whether Mythbusters has received some sort of kickback from oil companies as well as questions to how they performed their test. That is, using too much Acetone can not only degrade mileage, but can hurt your car's metal/computer components. There is documentation all over the internet that describes how the chemical properties of Pure Acetone combine with gasoline to help evaporate the gas easier; this, in turn, yields a more efficient system. The question though, is does it work? I am going to test it in the coming weeks and report back. The recommended amount is 1-2oz of "Pure" Acetone per 10gal of gasoline (any grade). This should minimize any negative impact on the car's metal, as well as provide a 10-15mpg increase in performance. I have an older car (2001), so I don't recommend trying this on a newer one. Let's say you have a 10gal tank that gets 30mpg. Total distance would be 300miles, with the Acetone it should be 400-450mi, to put things in perspective. So you're saving 3.33gal (100mi/30mpg) overall. 3.33gal x $4 per gallon =~ $13.33 USD Pure Acetone can be bought at $7.50 per quart (32 fl oz). So if you used 2oz per 10gal, that would be 16 tanks per bottle. $7.50/16tanks =~ $0.47 per fillup. So you'd be saving $12.86 total every time you filled your gas. If you fill your 10gal tank, once a week, you'd be saving $668.72 a year. I don't think the savings is completely correct, because I didn't factor in all the variables, but it is a good starting place to show how much this could affect you. If there was really a 10-15mpg increase, it would save a lot of people a lot of money.
2005 XTerra,. I own a 2004 XTerra and replaced the air filter with a K&N air filter (not the whole intake system, just the filter). It cost me about $50. This filter never ha…s to be replaced, just cleaned out every 50,000 miles. It gave me an extra 1-2 mpg more and increased the horsepower a little. hope this helps you out.. 2004 XTerra
Join our trailblazer enthusiasts forum at www.trailvoy.com There are a few good options to improve mileage a fair bit. There is a lot of stuff to read and most questions …on the forum get answered really fast. You will want to read about K&N intakes and a "TUNED" PCM. The exhaust on these trucks is very free flowing and has only enough restriction to make the VVT work properly.
Rotate your tires every 3,000 miles. Change the oil at that time as well. Another area to look at for improvements on gas mileage is also your air intake sensor and air filter…. If your air intake sensor is dirty, it will cause your engine to change the ratio of your air to fuel mixture. I've wiped my sensor off with just a q-tip and removed what seemed to look like soot from it. It helps. Change the airfilter when you notice the sensor getting dirty. If the sensor looks real dirty, you might need to replace it.. On older vehicles, I've used the sea foam product in a full tank of gas. It blows the carbs out of the engine, which makes it run more efficiently and adds life to your engine.. Other things you can look at just to improve overall gas mileage: make sure you're not carrying around that extra bag of dog food you didn't haul in the night before; run your AC in moderation (put it on the mid setting instead of running it on high, then turning completely off once you're comfortable); don't drive with all the windows down to compensate for not using the AC (this causes quite an air drag on your car and you'll use more fuel to just go forward!) . Driving anything over 65 mph burns more gas (so they say), but good luck staying at that speed on the interstates where 75 mph is the speed limit and those around you are doing 90!
\n. \nHi there i seem to have the same problem since I got the 5.9 magnum durango I been saving some gas by not using the piece of 5h1t and using my girlfriendÂ´s maxima ma…ybe you can do the same or by getting a bike.\n. \nAssuming everything is running OK, you can change your driving habits by driving slower on freeway (55-65mph), accelerating slower, leaving more slack space between vehicles during heavy traffic to avoid constant brake & accelerate cycles. Ensure tires are filled to max allowable (reduces rolling friction). Better grade spark plugs will ensure more complete burning of fuel and liberation of more energy to transfer to drive train. Avoid high traffic time periods, plan trips for late evenings or early mornings, utilize cruise control to maintain 55-65 mph.
The gas mileage on a 2001 Millennia S can be improved by performinga tune-up. This includes replacing the fuel filter, air filter,spark plugs, and cleaning the injectors.
Make sure you tires are inflated to the correct pressure, take off slowly, drive the speed limit, make sure your air filter is clean, make sure your engine is running as it sh…ould. Other than that noting else is cost effective.

Generally speaking, mufflers don't improve gas mileage. They reduce noise by disturbing or smoothing exhaust flow. That said, an excessively restrictive muffler can increas…e exhaust backpressure causing the engine to labour and decrease efficiency. In this case, replacing the muffler with a less restrictive unit can improve gas mileage, but the same can be achieved by eliminating the muffler entirely. In some (uncommon) cases it is possible for a muffler that flows too freely or is missing to cause the engine controller to operate in a less than optimal mode. In this case, an original type muffler can help by restoring the state of tune. The same effect can be achieved using a baffle or simply denting the exhaust pipe appropriately.

Keep them properly inflated and balanced.
