MPG Issue

[SR5longbed]

Has anyone had issues with their MPG? When I finally ran the damn thing to E and filled up it only took 20 gal. I was told it had a 26gal fuel tank which would average to 11 something gal. if it only has 20 that would at least be like 15mpg. Why would the make such a great truck with a 20gal tank?

thats been my question from the beginning - everywhere says a 26 gallon tank but mine only takes up 20 gallons when i run it until the "light" comes on .. maybe it has some sort of reserve or the light comes on when you have 100 miles to go? haha idk

I noticed the same thing. 5 to 6 gallons in reserve is quite alot.

yea exactly .. but ive never ran to empty so i have no idea

Ya but the pump doesn't lie. 20 gallons is 20 gallons! But I guess that doesn't account for what's left after the light comes on. Hmmmm.

Ive been tempted to run it out and carry a full 5 gallon can with me to test it out. Do you guys know if running it out of gas would create any problems with getting it started again right away.

I was just gonna suggest that! I honestly don't see how it could hurt.

Not sure why it is an issue... Refill at 320miles town use or 400miles highway. I have put up to 21.8 gallons in mine as i continued to drive for a bit on "E"...

I think I'm gonna try it. It will be near the end of next week before I have a result to report.

If you search for this issue, you'll find that this experiment has been done quite a few times by members here and on the other Tundra forums. If you run it out of gas, it takes ~25 gallons to fill it up. About 1.5 gallons cannot be scavenged by the pump.

But I agree the light comes on a little early at ~20gal. This question comes up about once a week.

Yep. You'll also get a "warning beep" at ~24gal mark.

interesting

I dont know bout yall but i did the math and the trip i just took i filled up two times more than I would have had too with a tru 26 gallon tank. That pisses me off. who in their right mind would buy a truck with a "350" with a 6 cylinder gas tank in it when gas is at $4 a gallon. Me and toyota gonna have a talk about that tomorrow.....
