Toyota Tacoma "Real World" Gas Mileage

I feel this. I had an s10 w/ a 5spd manual and thought having the 6th speed in the Tacoma would be awesome. I'm kinda disappointed with the gearing. Also, Hello fellow NHer!

 

Either use GPS, or if you don't have one, use mile markers, zero one of your trip odometers, drive 20 miles, compare trip miles to the difference in mile markers. If 1 mile off, that's a 5% error, .5 mile off is 2.5%.

 

06 4X4 access-cab with 265X75X16 E tires, 16 in town, 19 highway

 

where can i get speedo adjusted?

 

not exactly strange... They seem to gear the manual trans loooooow as fk. Maybe to compensate assuming we will lift them and put huge tires?

 

I just installed 265/75/R16 Duratracs this weekend. Here is the info I have. With my stock 245/75/16 Dunlops (31 Inch Tire) my speedometer was reading to fast. Drive 100km/h (GPS) and speedometer read 104 ish. This is a known issue with Tacomas and 31" tires. But Odometer was pretty close maybe read slightly higher then actual GPS mileage but very minimal. With my new 265/75/16 (32 Inch tire) My speedometer is bang on to GPS. My odometer is reading low. 53.48 km driven (GPS) shows as 52.0km on odometer. So my truck will look like it has less miles on it then actually driven.

 

One other thing, do NOT assume speedometer and odometer are "off" the same amount. My experience with P245-75-16 was odometer way off less than 1%, or less than a mile per 100 miles while speedometer read about 63 at a true 60mph. So just because your speedometer is NOW in agreement with a GPS, your odometer probably has more error than with original tires. Also, my P245's lost a full inch in diameter at 37k miles when replaced. So, as tires wear, your speedo/odo accuracy changes also.

 

I get exactly what the site said...16-16.5 in the city, and 19.5-20 on highway, 4" lift w 285-70's. I bought my truck new in 08, and have calculated this with probably 80% of the life of this truck.

 

I'm at 15.8 mpg 90% city 10% highway. Its been the same for the last year regardless of winter gas.

My only gripe is the size of the tank, I wish it was at least 25 gallons.

20-23 city depending on time of year.

 

This is true, I can confirm with with brand new 265/75/16 my speedometer is dead on and my odometer is only showing 97.18% of actual.

 

I get about 14-16mpg 75/2 street/highway. I feel like I should be getting more, also has a noticeably louder ticking sound, and a slight loss of power. I have k&n cold air intake, also no codes ever come back.

 

After my 30k maintenance I'm actually getting close to 20 mpg. Before I was only getting 17/18ish so I'm pretty happy. My truck is stock.

 

My truck is stock with an ARE shell but I got the same kind of mileage before the shell. 98% of my driving is city and I usually get around 13.8 with a little highway thrown in I'll get 14 something. On trips I'll get 18. I try to keep it below 1500 rpms with gradual starts. I have never driven this conservatively. I know these trucks weren't real fuel efficient but I was hoping for a little more fuel economy. I'm coming up on 10,000 miles and will probably ask the dealer to check it over.

 

Something seems off.

My truck is modified and heavy and my driving is 90-95% city. Im at 15.8 mpg with a heavy foot.

Loco, my truck has 180k, louder ticking sound compared to other tacomas, I'm getting about 15 combined, driving almost half highway fairly easy, stock tires no lift. No codes as well as I stated earlier, do you think it could be intake valves need adjustment?

 

I would start by ditching that K&N cold air intake. Ive seen those systems contaminate the Mass Air Flow sensor and impact performance and mileage. There is no better setup for reliability than the stock intake and paper filter.

As for the valve noise at 180K you could benefit from a valve adjustment too. But Im not sure it will greatly improve your fuel mileage. If you have problems with hard starts or a rough idle then for sure go after the valves.
