How to increase HP and gas mileage in Tundra

[klconsco]

Very good reply on the drive slow. How about stop MISLAEDING people with 16city/20 hwy on 2007 5.7L Tundras. Try posting reality 13 city/ 17 hwy No one I know with new Tundras get anything near 16/20. Driving like my grandparents is not real. STOP MISLEADING. Toyota Engineers should design a chip that will give consumers and option of less torque and better gas mileage (At Least 16/20 at a minimal). How many people pull 8500-10500#? Most people haul people only. TORQUE & POOR GAS Mileage is not Necessary with $2.50-$3.00/ gal. gas.

If you read the fine print on the sticker, you will see the standard "Your Mileage May Vary" disclaimer.

These mileage numbers are calculated by the EPA under very controlled conditions; the exact same controlled conditions as every other car or truck sold in the United States. The purpose of this is to establish a level playing field for the purposes of comparing vehicles. It is not a guarantee that the vehicle will achieve the listed mileage in the real world.

Once you get out in the real world, there are an infinite number of variables to contend with. Some people live in the mountains and some live in flatland country. This can affect mileage. Temperature and humidity variations from different climates can affect mileage as well as the current local weather conditions and other environmental conditions. The amount of weight your vehicle is carrying will affect the mileage. A vehicle with a full tank of gas gets less mileage than an empty tank, because a full tank weighs more. The grade and quality of fuel can affect mileage. Different blends of fuel sold during different times of the year will also affect mileage.

It is unrealistic to expect to get the mileage that is posted on the sticker. All you can do is practice good driving habits, and keep you vehicle in top condition and try to get every mile per gallon that you can.

klconsco, I'm sure Cyberbilly can back this up, as i understand it Toyota does not come up with those numbers. The numbers come from a federal organization that does the EPA estimates for everyone. Also, their are so many variables that can change the mileage. In the city the distance between stop lights (the amount of times you come to a stop and accelerate back up to speed), is the traffic between stop lights driving at consistent speeds or are they brake happy, the altitude your driving in, etc.
I don't know anyone that buys a truck for its gas mileage. Yes it would be nice to get better gas mileage out of these trucks, but I bought my truck to haul a 24' enclosed trailer full of tools. My '05 with the 4.7 hauls the trailer pretty good but the '07 with the 5.7 would haul it better, so you better beleive that torque matters.

I own a 2007 Tundra Double cab 5.7 4x4. I have put 1500 miles on it so far. Driving has been 75% highway, 25% state roads with no or few traffic hangups. I live on the Maine coast. My experience has been as follows. My best mileage is 20.8, worst is 16.6 and average around 18.2. I formerly owned a 4.7 2003 Tundra Access Cab 4 x 4. My new Tundra Double Cab with much increased horsepower. definitely appears to get better mileage than my older Tundra. By the way I added a Retrax bedcover on my 2003 Tundra and it did increase the mileage on trips. I intend to put one on my 2007 Tundra as well. I have been advised by my Toyota dealer to purchase Toyota's TRD Air Filter which lasts "forever". Supposedly it will increase gas mileage 1 to 2 miles per gallon. Has anyone had experience doing this and, if so, what are the results?

Keep in mind that as every new generation engine comes out, the quality improves. The 5.7 in the heavier truck probably gets better mileage due to newer technology.

I'll assume when you said quality, you meant technology also.

There, there, Snowflake...Daddy loves you....

I meant both.

[markw76]

I haven't researched it much, but I'll take your word for it on quality. Toyota beats almost anyone else for reliability and I haven't had any serious events power train wise. I'm currently about a 10K/yr driver though. So far, quality gets very high marks.

You can spend a lot of money, but if fuel consumption is an issue, then the cost of modifications is also an issue, and the only thing you can do to save fuel that pays for itself is to avoid carrying unneccesary weight in the truck, air up the tires, and drive slower.

Say what..! Isn't much to improve fuel mileage\consumption..??? Sure there is. Custom air filter (K&N, AFE, ect..), custom muffler (Magna Flow, Flowmaster, ect..) both of these for about $100.00 I recorded (at 70 to 75 going north on I-5 to Oregon) a high 22.8 mpg with just the muffler. I recently added the air filter and haven't re-recorded the fuel mileage again. I know it's increased. By letting more air flow through the engine, it gains more HP and less fuel use. There's also the use of headers.. more power=less fuel useage. Now we're talking much bigger dollars, but will pay for themselves in the long run.

Like you said.. tire pressure is a HUGE factor.

I useed the trd filter for about a year but recently removed it. I didn't see much improvement in mileage or performance at all. It just made the engine louder which makes it seem faster. Evidently, when i cleaned and re-oiled it once I got too much oil because my mileage suddenly deteriorated dramatically. I replaced the filter with and oem and had to clean the mass air flow sensor and reset the ecu. my mileage immediately improved by a couple of mph. I'll never waste money on another TRD filter.
Anyone want to buy my used one?

[Lockjaw]

You can laugh at me if you want, but I put a tornado in my truck, and it gets better mileage. I have gotten as high as 20.xx on long trips at 75 mph or so with the cruise on, and the cruise is very agressive if you ask me.

My only mod's to the truck now are synthetic fluids everywhere, a K&N filter and a dynomax cat back exhaust.

Headers are coming eventually.

I agree do not goose it and keep under 60 mpg. I met an elderly man who claimed to get 30mpg on a 4.7L tundra same as mine claimed if you kept truck under 55mpg could get this milage. Did not believe. Decided to try traveling 55 on a trip got 19.5 on return trip drove 60mph got 18.5. The man had miscalculated the gas purchase.

Must have cause 30mpg is pushing it literally.

Mine wouldn't get 30mpg being towed.

I put an AFE cold air kit ($420) and a Airraid throttle body spacer ($80) on my 5.7L 07 Tundra. There is a noticeable increase in throttle response and midrange power. Also according to the built-in mileage tracker I have slightly increased my fuel economy.
