2nd fill up <17mpg??

Hmmm, how is this possible? 16.7mpg? from a 4cyl and I drive it easy. All city driving bat geeez, last tank I got nearly 19mpg mixed driving?

Does the AC suck that much gas? I've had to run defrost a lot lately.

 

How many total miles are you at??

 

very possible my friend... drive all highway like there is a Fabregé egg under the gas pedal and see how you do.

 

cold temps hurt my milage baaadddd!! i can usually get almost 19 mpg mix ( by mixed i mean 80% city, 20% free way) with a 6 cyl 4x4. Not sure wehre u are but the when i hit the moutains that really screws with the milage too. But yeah that doesnt sound right for a 4 cyl

 

i'm only sitting at about 13.7 to 14 mpg. It sucks but thats how it goes sometimes.

 

I have a 4 cylinder also and get about the same. Not sure how a 2.7L 4cyl only gets those kinds of numbers, but it's not going to change, so I try not to think about it lol.

 

44,500 miles. New airfilter, oil etc.

Wow, that's crazy!

Well, it's still almost double what I get in my GMC so I'm not complaining too loudly

Just a note, on my recent trip to Lake Tahoe, our '99 Camry LE V6 got 29mpg cruising at 70mph!! Wow, I was surprised.

 

The cold hurts, but man, I'm getting that in my six in cold weather.

 

That sounds horrible. In my v6 mostly city driving and warming the truck up every morning I am still getting 18mgp, during the warmer months I can get around 19 and have seen 20 a few times. I thought the 4 cylinders were getting just over 25mpg

 

I don't think my truck could get 17 MPG even if I was running WOT everywhere...something can't be right.

 

Yeah 16.6 actually...I topped it off and am recording milage again...I'll see how tank 3 does in 2 weeks.

Stock tire size, stock airbox, stock everything. Maybe a nice MAF sensor cleaning will help?

 

I'm always surprised at how bad gas mileage is for stockish Tacomas. I have 35's, front and rear plate bumpers, winch, skids, sliders, dual batteries, 35" spare and more extra weight and I still average 16mpg mixed and 18ish on the highway. I get a little better mileage in the summer.

 

Suggestions to improve? Next oil change will use synthetic but I wouldn't expect a big bump with that alone.

 

Have you checked your tires? They lose pressure in the cold and can cause a drop in MPGs if it is too low.

 

Check the air filter and check tire pressure. Maybe try running some seafoam or something similar before your next oil change?

 

How many miles on the truck? I'd check the spark plugs. I'd also check to see if the cat is clogged or the o2 sensors.

 

Not sure, I think there must be something wrong in the calcs you are doing, I keep a daily record including the gps approximate elevation of fill-up when doing hwy travel. Because I travel from Yuma which about 150 feet elevation to Greer which is about 8500 feet. Even going Interstate 40 from Flagstaff to Albuquerque I get the same. I have almost constant 17mpg, one time I hid 20mpg but that was hot flat desert highway between Yuma and Tucson.

V6, manual 6 speed, small camper shell about 450 lbs with extra gear, which includes a couple of extra batteries for the HAM radio, 265/75-R16, at a high a pressure as allowed - 35 to 38 lbs

 

thanks, I haven't done more than a visual ... I'll get a gauge on those tires this weekend. Air-filter was replaced recently. I don't believe in Seafoam although I know many people use and swear by it...I'm chicken I guess.

Calculation is simple math but I'll double check it next tank.

 

did my first fillup today and got 20.5 mpg with 80k on a used 06 4cyl 5spd 4x4

 

I put 102k on my 05 4 cyl 4x4 and tracked the mileage regularly. I never saw less than 20mpg but my driving is mostly highway. Now with my V6 4x4/auto I seem to be getting 19.2-19.5 no matter how I drive it. I know it's got a new air filter but I have no idea on the plugs. I would love to see 20-21 out of it.
