Wow! 16.5 on my first tank, mostly city and medium speed rural. I'm surprised it did that well on a green engine with alot of time spent parked at idle playing with the gadgets. Never could do better than 12 with my old F250 diesel.
#28 of 65 Toyota Truck History

I have had 6 Toyota trucks dating back to 1981, still have four of them, latest is a 2006 Tundra Double-Cab Limited. All of them continued to improve on mileage up to 60,000 miles. IMPORTANT: After 10,000 miles, I switched to synthetic oil (Castrol Syntec, or Mobil-1 extended mileage) and achieved an average of 1.5 mpg increase on every one. That adds up to a substantial savings in gasoline cost.
Regarding the new 5.7 liter Tundra in towing:
Because the intelligent variable valve timing achieves >90% of peak torque over >60% of the RPM range, and the peak torque of 401 ft-lbs exceeds that of Ford, Chevy and Dodge (including the Ford F-250 and Chevy 2500 diesels, see the latest Consumer Reports write-up), the achievable mileage while towing any given load up to the vehicle's limit should be superior for the Tundra relative to its competition.
Towing 2200 lbs with either my 2000 Tundra SR-5 or my 2006 Limited, I tend to forget the trailer is even there.

Hi: I have a 2007 double cab with the 4.7 motor. In a effort to get better MPG I'm thinking od adding a 5" rear and 2" front lowering kit. I bellieve that this will increase MPG and experience with lowering kits or real world experience?

Don't think you will save enough to offset cost.

Trailerboats towing mpg 8.1 mpg at 65mph towing a Sea Ray 220 sundeck empty.
In our “Double Nickels” scenario, we towed a Sea Ray 220 Sundeck completely empty, and covered its bow and cockpit to reduce drag. We made sure the boat and trailer were level with the truck, and checked that all the tires were filled to their recommended psi. We also never drove faster than 55 mph on our test route.
In our “Speedy” scenario, we kept the same setup, but drove 65 mph instead of 55. This change in speed will answer whether it’s worth resisting the temptation to travel at the rate you are accustomed to when not towing.
In our “Does It Matter?” scenario, we really messed with our rig. First we dropped the air in the Tundra’s tires to 25 psi, down from their original 35 psi. Then we took off the Sea Ray’s covers, and even latched the door separating the bow area from the cockpit for some extra wind resistance. Finally, we added 500 pounds of weight to the boat, in the form of a dozen 5-gallon buckets filled with water. The 220 Sundeck has a 50-gallon fuel tank, so this weight is the equivalent of driving with a full tank of gas and 200 extra pounds of gear.
The Tundra’s computer confirmed what we experienced on our test route. In our “Does It Matter?” scenario, we achieved only 8.0 mpg, compared to 9.3 and 11.1 mpg for our “Speedy” and “Double Nickels” circuits, respectively. The actual numbers showed the trip computer was being a little generous, however. Our data, based on gallons burned and the miles we traveled, showed only 7.3 mpg for the “Does It Matter?” loop, 8.1 mpg for the “Speedy” scenario (an 0.8 mpg or 11 percent improvement), and 9.9 mpg for the “Drive 55” setup (a 2.6 mpg or 36 percent improvement).

Hi: Does any one have real world experience with putting a 2" front, 5" rear lowering kit on a 2007/8 2wd Tundra? I beleive that with a less large profile to the air the truck should get better gas mileage.
