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 4-20-2009
Posted 04-20-2009 at 06:21 PM by Highwaylizard
Filled up today:
What makes this set of numbers even more interesting is that they were the return trip with a 500 pound mower in the trailer and without cruise control. For most of the trip I maintained a pace a little over 70 miles per hour. I am a little confused as to why the freeway mileage with a trailer is better than the in town as I would have thought the added wind resistance would have canned the numbers. I think the in MPG town is less than the freeway MPG due to the constant stop and go from stop light to stoplight as well as the multiple start-ups and shut-downs of the truck from one property to the next.
It may be possible that the truck is lacking low end which I think can be cured with headers. The next set of modifications will include the reworked intake paired with a set of headers. It would be nice to install a set of long tube headers but they come as a kit with catalytic convertors for a little over $1,000 which, absent a funder or sponsorship, are completely out of reach of my budget. I will try and find time to draft some proposals for a few manufacturers to see if they would consider sponsoring some testing. The economy has dealt a horrific blow to my business and the out of pocket expense of continued testing simply cannot continue.
