Set up a spreadsheet and plot out your MPGs and see if the trend is up or down...
Yep, just like this.
I update it once in a while but keep a hard copy in the glove box and pencil in the numbers then take it to the computer to enter in the numbers.
*EDIT* Notice April 16 & 25, pretty accurate to me anyway. I can easily change my MPG by changing my driving habits. But I don't drive to save money, I drive to have fun and if that means full throttle after every stop, that is my choice.

The only way to get accurate numbers tank by tank is by using averages, or by using high quality fuel flow meters before and after the injectors.QUOTE]
Ok, I might be uneducated here, but... how the h#:: do you put a flow meter AFTER the injector? Isn't "after" the injector inside the combustion chamber??
I'm assuming the the EFI has a bypass - I could very well be wrong. I've only ever done work on systems with bypasses.
20,000miles/15mpg=1333gallons
20,000miles/22mpg-909gallons
So you save 424 gallons a year. At current gas prices, that's over $850/year saved. And you help save the environment. A little too extreme?
You are comparing best case with worse case. If you use 17 or 18 for the pre-2005, the savings is closer to $500.
While I am rethinking my decision to buy a 2004, if I can buy a $44000 vehicle, I can afford $500 in gas. Also, how much more expensive with the 2005 with the more fuel efficient engine be? That must be taken into account.
We bought these vehicles for reasons other than gas mileage so we must live with it/
I just found a trick that gave me an extra 5mpg. The dealer who sold me the new truck sold it with a Tundra ECU. I just had that replaced with the correct ECU and gas milage improved dramatically
Best mod for improving fuel economy and increasing horsepower/torque is to buy a Dodge Cummins or Ford Powerstroke. Short of that, yer chasing a snipe. If Toyota doesn't pull their head out and offer some power with a manual tranny, I may be headed down that road myself...

How did you discover you had a tundra ecu and get a new one installed?
When the dealer went to reprogram the ECU as part of the "sulfur smell" TSB, they foud that they couldn't program it. They realized the part number was for a Tundra which was why it wouldn't take the Sequoia program (so I'm told).
Had they not done that TSB, my guess is that I may have never known there was the wrong ECU, and I would have kept just been told that things like power roll-off and rough idling were "normal."
We're just back from a month-long trip thru New York, Vermont, New Hampshire, Maine, New Brunswick, Nova Scotia, Quebec and back home to Ontario. If it helps the mileage debate at all, I have some "results".
For this trip we were toting around about 3800lbs of trailer and stuff. We also drove a lot of mountainous terrain, with and without the trailer, including the White Mountains in NH and the Cabot Trail in Cape Breton. For the 6,000kms of the trip our fuel consumption was 16.6 L/100 km or 14 US mpg.
The Sequoia performed like a champ the whole time, was of course very comfortable. In the end the gas consumption isn't far off what our minivan was so I can't complain giving the higher level of capacity, capability and refinement.

I understand that when people buy, they don't take into account that gas prices won't stay at 1.48/gal. When gas gets over $2.00/gal, then people start to look at ways to reduce that expense. Seems normal to me..
I am not sure I understand all this chasing a mile or two per gallon increase in by spending a hundred dollars or more. Lets just say I can increase my fuel economy by 1 mile per gallon when gasoline is $2.50 per gallon. My assumption is that I get 17 MPG and by investing $100 dollars I can increase my fuel economy to 18 MPG, about a 7 percent increase. Considering that the fuel cost per mile are $0.147 and $0.139, respectively ($2.50 divided by MPG). This results in a decrease in fuel operating cost of just less $0.01 per mile ($0.008/ mile). If I consider an investment of $100 dollars, it would take 12,500 miles of driving to breakeven in the investment ($100/ $0.008/ mile), for me that would be a little less than one year. The more I consider it, I think if you are worried about saving money, go out to eat one night less per week and the return on investment will be greater. Enjoy your Sequoia and its wonderful features the way I will and don't chase pennies with dollars. Invest in things for you Sequoia that will enhance longevity, power or comfort and accept the it is a big vehicle with wonderful features that will not get 22 to 28 miles per gallon.
