16 mpg?

2000 Prerunner2.7,auto,sea level,fresh plugs,filter,i have put shorter tires on, then a topper nothing changes and I drive slow, the very best I have gotten is 16.5,is this pretty average?I had a 95.5 v6,5 sp,4 wd that got 18-20 when I lived in Colorado at 9000 ft elavation,still kick myself for letting that one go

 

'99 Prerunner 2.7 auto at about 12ft above sea level and I get 17ish mpg almost all the time. I've got 3rd gen Tacoma wheels/tires. Also new plugs/wires, filter, no added weight. Lots of other things done to it as well.

You're definitely in the ballpark.

 

Best I ever got was an average of 14mpg between loaded and empty on a 500 mile round trip.

 

define "shorter tires" ?

 

I’ve been averaging 20 for a long time. But mine is single cab and mt with locking hubs, all which help.

16 seems low, but could be normal depending on how it’s driven and what kind of trips are being taken

 

16 is pretty reasonable I'd say. Here are my averages for the last several years, with 33" tires, 4.88 gears, and a truck that generally weighs ~5500lbs. I drive like a grandma though, trying to eek out the best mileage possible.

2016 is when I started building the truck; before that, it was a stock daily driver (that was rarely driven). I've lost the data from 2004-2011 (or rather, it was stolen out of the glove box).

 

I get 16 gallons per mile.

 

I’m 21.5 every tank with heavy 265’s but I have a manual trans, short shift and cruise at 70mph.

 

What's your gearing and what did you use to adjust your ODO to account for the 35s?

 

GPS checked with 4.10 gears. I do a lot of highway driving.

And they are not 35’s, 265’s which are like 32x10.50’s

 

Milage isn't the best.

 

my 2009 5 lug 2wd gets 24 mpg

 

My 3.4 gets about 18 or 19. 4WD auto.

 

2k taco 4wd manual w/3"lift. I think I get like 10 MPG in my truck.. Lots of stop and go city delivery driving . about 21-22 mpg freeway i'd say.

 

I ran my 2001 Prerunner with the ECT button locked on all the time. I don't recall my mileage now but I know it was over 20 mpg. Have you tried that? Seems like mine got better mileage when the RPMs were a little higher. Might be worth a try.

 

2.5" lift, 32" on 4.10 gears. usually 13-14 city driving, 18-19 highway

I'd say you're right in the range

 

I have a '04 single cab auto PreRunner, and used to have 265s with 4.30 gearing, and I got around 17mph.

I recently switched to 235s, and 4.88 gearing, and I'm getting 24mph now. This isn't completely verified, as I am still breaking in the gearing, but that's after 1/2 tank.

 

is that accommodating for the change in gears? assuming you went from 265/75 to 235/85 right?

 

It'll be interesting to see what your average is after several tanks.
You're speedo and odo are probably off after the regear though.
