This blog is about my search for better fuel economy for my truck. I have a 2004 Toyota Tundra Double cab with a V8 engine, four wheel drive, and a four speed automatic transmission. Of all the years the Tundra has been available it appears that the 2004 DC truck, because of its size and engine/transmission configuration, gets the worst mileage of all the Tundras. The Gross Vehicle Weight of the truck is 6600 pounds and the EPA fuel economy rating for the truck is 14 mpg in the city and 17 mpg on the freeway. In all honesty these fuel economy figures are both generous and unrealistic.
I have a personal Blog with more detailed information about my testing and my findings. Detailed spreadsheets of my fuel economy and test conditions can be emailed from my email account at highwaylizard@gmail.com

MPG Numbers 6-12-2009
Filled up today:
These numbers are excellent considering that at least half of the miles were generated pulling the trailer. Even so, since I am behind in writing these posts I noticed that in the next set of mileage numbers my passenger side oxygen sensor on the passenger exhaust manifold failed. I am wondering if there is a correlation between a spike in the fuel economy and the failure of the O2 sensor. Not to say that the increase in mileage caused the failure but rather that the failure was predicted by the momentary rise in fuel economy. I need to go back through my records and find if there was a mileage spike prior to the failure of the driver’s side primary O2 sensor.
As always, if you have any questions please do not hesitate to email us. For more information about my testing take a look at my personal blog at Tundra Fuel Economy. Feel free to drop in, look around, and drop some comments or ask questions.
