Hey All,

Yep, I'm a noob here. Have a qestion about the new Taco 4-door Prerunners. My cousin wants to get one and has been waiting for the 07's because he says they get 7-8 miles per gallon better mileage than the 2006's.

Can any of you confirm this, and if so, HOW was this increase achieved? New tranny? New engine? (fudged the specs?)

Thanks for any input.

I can't confirm but I would say they would be lucky to get 1 mpg better. I wouldn't count on an increase at all.

Interesting - I thought all the 4x4's and Prerunners listed at 17-21 in 2005 and 2006. I wonder what the difference is?

Troy - Does your manual recommend 5W-20 motor oil?

My '05 DC 4x4 is EPA rated at 17/21 city/hwy. Its '07 equivelant is rated 18/21. Insignificant, and possibly due to 5W-30 oil advised for 2007.

Prerunners have an identical increase, up from 18/22 in 2005 to 19/22 in 2007.

These figures are for V6 Doublecabs. See Toyota's website for other models.

CMOS, your cousin is mistaken.

On my 05'
Dbl Cab Long bed pre-runner
I get 21- 23 hwy on 91 octane, if I keep it under 80mph

Avg. this on a 900 mile trip from GA to TX

5W-30 is what the 05 is specrd for too.

Specrd?

You are correct, sir -- what I meant to say was 5W-20 for 2007. :

19/22 here on my Prerunner

 

[tim.powerbook]

i wouldn't image an increase on the 07 either....

for the 4 cylinders....they went from 20/27 to 23/28 i believe....

The increase is EPA numbers is from the use of 5W-20 oil.

They didn't print out new manuals for 2007 because they released a TSB recommending the use of 5W-20 oil in various 2007 engines. I know the 1GR-FE was one of those engines. The link to the TSB is around here somewhere.

Whether you know it or not, the 2007's came with 5W-20 from the factory. That's where the increase came from. 7 or 8 mpg sounds a little heavy but 1 mpg sounds about right.

^Thanks boone. That's sort of what I figured.

THere were some debates a year or two ago on the Acura forums when Honda/Acura switched all their oil recommendations to 5w-20 as to whether or not it was "safe" long term to run 5W-30 in those engines. Some debated that bearing clearances were altered to account for the thinner oil, and that 5w-30 wouldn't perform as well.

I think it's safe to say that the engines didn't change at all, and that auto makes are just changing their recommendation to achieve better MPG numbers for CAFE.
