Various taco questions...

Hey guys need some help on a few things. I have had my 02 quad cab taco for a month now and I am only averaging about 14mpg. This is mostly highway driving! I have done the usual things, changed air filter, checked tire pressure, and changed oil. After I changed the oil to RP 5w 30 my average went up to 15mpg. Any ideas what is causing the bad gas mileage? Second, checked the oil tonight and I am already down one quart from my oil change two weeks ago. No leaks. This was the first time that I have run synthetic, so could that be the cause of this? Last, I have noticed that when in 4 wheel drive, if I reverse or drive forward slowly with my steering wheel at lock right or left, there seems to be some binding (truck doesnt want to move). Is this normal, I dont have a lift on my taco, or bigger wheels or tires. Any help appreciated, thanks guys....

 

try changing ur diff fluid ,it might help on both ends

 

yep....try changing the diff fluids....maybe all to synthetic, as well as the transfer case. for a little better mileage.....clean the throttle body and change the fuel filter. also....seafoam the motor.........shou.d get some mileage back. how many miles you got on the tacoma?

 

93000 miles on her

 

yep.....i'd say time to do what i mentioned.....you'll get some mileage back definitely. did you do the deck plate mod yet?? if not......do that too man......it'll really help.

 

I have an 09 Tacoma, I only get 18 mpg on highway. What do you guys get? Anything better?

 

Havent done the deck plate mod yet, whats the mpg increase

 

if you have the v6.....thats about right. switch over to synthetic oil, and switch the transfer case and diffs over to synthetic oil too.....and give the truck some break in time.....the mileage will definitely get better.

 

well......i cant tell you a definite, but im getting around 20 mpg now....on crappy winter blend gas..............and i have had up to 23 in the summer..................and i run full synthetic everything, have the deckplate and an exhaust....on my 04 double cab.

 

my mpgs dropped a ton with the cold+ winter gas. I used to get around 15 in winter with the 4 runner that had the same engine. then it would shoot to 18 and 19 in summer.

 

yeah.....winter blend gas will kill fuel mileage for sure.

 

X2 on seafoam... that stuff works wonders!!!

 

Seafoam is awesome... did it to my DD...

 

I seafoamed my engine a few weeks ago, and I was planning on seeing what mileage im getting now, but I got injured at work and havn't drove my baby in 3 weeks. I was getting about 15mpg. So if I hope the seafoam helped me out. If not I guess i'll try changing diffs, and Trans. case to synthetic.
