I got a 2011 4.6L Tundra, I'm not worried about loosing HP but id like to know if there is a way to squeeze an extra MPG or two out of my truck without major mods or breaking the bank?

Thanks

 

Be light on the throttle, try to time the traffic lights so you don't have to stop. The biggest improvements will come from the driver

Agree with corax, either that or buy a Prius! lol

 

keep the weight down

install a vacuum gauge and keep it low

 

Lay off the gas pedal and slowly accelerate. Ease off the gas on downhills and don't hit the gas on uphills. I guess the best way would be to put a bio-diesel engine in it. By not accelerating too fast, you should save some gas and keep the rpms down. Or you could put it on a flatbed trailer and pull it. The Tundra would get great gas mileage, your tow vehicle wouldn't.

 

Keep your tires inflated 2 proper psi when driving in the streets or highway

 

. . . or inflate them 5-8 psi over the label on the door jamb (not tire sidewall) to reduce rolling resistance, but expect a slightly bumpier ride

 

I drive mine like a grandma going to Sunday church, and get 13.8mpg.

I do have an O2 sensor that is out, but don't think mpg will go up much when it is replaced.

I do love the towing capacity, and the ease of T-belt replacement.

 

Wouldn't hurt to adjust the valves.

 

You mean high right? Higher vacuum is better mpgs as far is I know.
