Best way to improve fuel economy, buy a different vehicle:D If you are referring to your Tundra there is not a whole lot you can do. I'm in the same boat, they are NOT great on fuel and that's that.:( Other than making sure your tires are aired up properly and changing the air filter regularily and possibly using synthetic oil there is not much else you can do. Some people report slight mileage gains by installing exhaust headers but the high cost of these will likely offset any minor mileage gains. Another thing you can try is to disconnect your battery for a few minutes to reset the computer, I noticed a slight improvement in my city mileage after doing this.:)

The best way to better fuel economy with your tundra is to never turn it on.:clown: Seriously though you can do a couple of things to help yourself like keep the tires properly inflated, run with a clean air filter, avoid jackrabbit starts and stops and don't carry around unnecessary weight. The quality of the fuel you run also plays a part in your mpg as well as whether or not it is oxygenated.

Even if it did, which is questionable, you'd need to see a roughly 11% gas mileage increase (say from 15 mpg to 16.6 mpg) to make up for the increased cost (from $2.79 for regular to $3.09 for premium in my area). And that's just to break even.

You can improve your driving patterns. Meaning, when you run errands, do them all at once, rather than 4-5x a week. Avoid traffic jams, and leave earlier for work. When going across town, take the expressway rather than through town. Even though it's more miles, all those stops and starts kill fuel economy. Finally, try a better oil next oil change - like Amsoil or Royal Purple. It may not improve fuel economy, but your engine will run smoother, and you'll not need to change the oil every 3-5,000 miles.

Ive heard that using Premium Gas improve your gas economy, is this true?
It might but the extra cost for Hi test offsets the mileage gain, so it really ends up costing you more money; not less.

What is the best way to improve your fuel economy? Besides driving slower.

I see from your signature you are planning on lifting you truck and adding bigger tires. If you are serious about better fuel economy, do not do these mods., especially the bigger tires.

I have had success with a K&N air filter. My mpg have improved from 15.25 to 16.8 all city driving. People have had mixed reviews of K&N products on this site but I have not had any problems with mine.

Driving slower is not as important as accelerating more slowly. You can go fast on the highway and as long as you keep the rpm's at or near 2000 you will get good mileage (for a tundra anyway). Floor it off the start every time and your mileage will decrease substantially.

Try to combine trips so you aren't driving a cold engine.
Those 2 mi trips up to Lowes, etc. absolutely kill your gas mileage.

I have an 07 5.7 DC:
Do you know the part number for the filter?
Does it require any modifications?

Thanks,

I've said it before, drive only downhill! Seriously, I live in a hilly area and drive the same roads frequently. Many places I can coast (illegal in my state but don't tell anyone) from a short ten or fifteen seconds to over a quarter mile without loosing speed. There are other places I start at the top of the hill well below the speed limit of 55 and am doing 65-70 by the bottom of the hill. You pay going the other direction because it's obviously uphill. It is easier since I drive a stick, but I do it in my wifes automatic as well, just takes more practice. Another place I coast is up to red lights. As soon as I see it turn red I'm in neutral. This also saves brakes since, in your automatic, you also have to slow the engine to bring your truck to a stop (take your foot off the gas and see how fast the truck will continue to go on its own). Unfortunately, some of my habits annoy those who like to go as fasts as possible and brake as hard as possible, so I also pull over a lot to let those guys and gals pass. Since you are only sixteen, these are HARD habits to develop, but they will save gas. WB

I just got done watching Motorweek on the Speed Channel. They had a feature on a book written by Ronald Weiers, Ph.d titled "365 Ways to Save Gas". You can save 10-20% on gas. Don't tap brakes. Back into your parking space. Arrange errands so you make your most distant stop first. Avoid clip-on flags. These were among the tips. check it out: MotorWeek: Inside Track: FYI

I would LOVE to be paying $2.79 for 87 octane. Where I live it is $3.05 now. :mad:

I just checked K&N's website and they have not made a drop-in filter for the 07 Tundra yet. The one I use is simply a drop-in replacement for the OEM filter; no modifications needed. One thing to keep in mind is that you have to drive about 3000 miles before you will start to see improvements, at least this has been my experience with them.

thats it? ****, here is cali, it's now at 3.35. **** sucks.

as for driving under or around 2K rpms, that really seems to work for me. i have notice that i'm getting better MPG when i drive under the 2K mark. trust me, it's hard to do, but it's worth it.
