Chris I’m not sure if we have a changeable fuel filter. Like the Ford and Chevy I had, all 3 were on the driver’s side underneath the driver’s seat to the rear seat area. I haven’t seen where Toyota hides their’s. I do alot of highway driving. 28 miles to work. 1mile of 4 lane 65/55mph to interstate then 19 miles of interstate for at least 15miles of the 19miles at 70/55mph then the last 4 miles at 55/55mph. Then it’s on a 4 lane at 55/55mph for the last 8miles and on the last mile it becomes 40/40mph and 2 red lights. The second mph is what I do to get the max mph. I’m avg from 20-22mpg.

Yes , mpg increased with boost in psi. I also disconected the
battery for oprx. 1 hour. I drive country roads 30 miles to work, top
speed 65, 8 stop signs 2 slow zones at 45 and 6 miles through a town
with 5 stop lights. Not city driving but a fair share of stop and go
18.3 mpg on 2 fillups. Much better! Tomorrow 0-20 oil and filter
change and 600 mile trip this weekend . I think it will do quite well.
thanks again. Oh I did not change my fuel filter yet.

Chris – A clogged fuel filter could definitely hurt mileage. Older tires have higher rolling resistance because they have less tread…more of the tire is in contact with the road. Did the boost in PSI help the tire?

I use 40psi to be exact. The more you put in the more I feel the road. The truck will ride harder. I’m due for the same thing in changing the fuel filter. Maybe mine will increase and I can try for 25mpg’s.

Well boys , I have been reading blogs so much my eyes have crossed. However I ran across somthing interesting, seems a guy had the same simtums I had with milage and very slight loss of power . His truck has 28000 miles, mine has 23000. He claimes he changed his fuel filter and the truck picked up 4 mpgs. I wonder? It sounds possible! Now I have a theory on tires . Can tires break in and get softer, as in more rolling resistance? Air pressures in my tires from factory 35 psi I checked them yesterday 35 front 32 rear . I put maxair in at 44psi I can feel a big improvment as the truck rolls. Like it used to.

Chris – The battery reset can’t hurt, but the cold weather might explain the drop. Did you see the post about that last week?

Jason; I installed a TRD cold air box after my mpg’s dropped hoping to regain them. No accessories have been added , tire pres. has been checked now and then. I will make sure pressures are all up, filter is cleaned and oil is changed for my trip next month. The only drawback is Wisconsin temp in november could cost me some milage . Would the idea of diconecting the battery for 10 minutes reset anything? thanks for the help

Chris – The recommended oil is definitely going to improve gas mileage, but I can’t imagine it will make that big of a difference. 0-20 is less viscous than 5-20, but not so much so that it would reduce efficiency by 10%. Could be a combination of things – a clogged air filter, low tire pressure, and more viscous oil might combine to drop your economy. Did you add any accessories that would increase drag? That might explain it as well.

Chris from what I found out higher octane won’t change it. Synthetic oil is suppose to be better which is what I use. I do my maintenance at the dealer so I don’t know the weight but I do know it’s Castrol. I’m thinking maybe reset the computer by diconnecting the battery for 10 minutes so as to trick the maf sensor to think it’s new again just to see if it gets back your mpg’s. I’m sure Jason will chime in with a suggestion.

MICKEY; Thanks for the comment, my 4×4 might have gone 7000lbs with all my gear plus my atv and small trailer. I took three trips with this combo in the first 5000 miles with it locked in at 72 mph never saw under 17 mpg with a high of 19 ! thats including mountains in CO. and Iowa – Nebraska corn fuel , but thats a topic for another blog. And yes stock Michelin tires. You bet I was very pleased with this, my point is once I changed my oil I lost mpg’s 2 to 3. Now I ‘m lucky to get 15 with perfect conditions and a tail wind. I never check milage in the city so my figures are strickly long hyw. runs. What P.O.s me is why was my truck capable of this milage for a short period of time and now its not? I have also tried 87-93 octain fuel with and without 10% ethanol , not much change. I will try the 0-20 oil that toyota recomends . I have a 600 mile trip in november so I will try again. I’m not quite ready to give up!
