2.7 gas mileage?
Hi everyone. I've had my '99 Tacoma 4x4, 2.7, with 31" and about 90K miles for a few months now. I'm getting much worse gas mileage than I was expecting. I'm lucky to get 17 mpg, but 15 is pretty common. I'm not using the AC, the hubs are unlocked, and I'm shifting pretty short. Is this reasonable? If not, any ideas what I should check?
Thanks,
Tom

Older ones have 15-16 gallon tanks depending on how much of the filler neck you use and how much sediment is in your tank. You'd be suprised to see what came out of a '94 Jeep fuel tank I recently bought. At least 1/3 of a gallon of mudlike crap, almost 1/2 inch deep away from the pump and strainer.
I'd be pissed if I was only getting 15 MPG. I still get 19 on 32" tires, 4.30 gears, 202000 miles. When I first got my truck and it had no bed cap, tailgate down to reduce drag, and 28" tires I got 26 MPG on mostly level highway at 60 MPH.
I'd expect the fancy new junk to get at least 22 MPG at 65 MPH on a standard cab truck. I'd want 0-60 times under 12 seconds on a stock one also.
22RE swap anyone??
Edit: Short shifting dosen't necessairly mean less fuel used. It usually means more unburned fuel getting to the catalytic converter where it's wasted. This type of motor likes to rev kinda high where it makes its best torque. At least I have found this to be true on my old carbureated junk. I can't speak from experience on the 2.7 liter.

I get a steady 21mpg with freeway/city driving. I have a heavy foot with the 2.7 
It's an auto tranny, AC is never off. I was hoping to do better as I heard so V6ers get higher numbers...maybe a SC would help.

I get around 15 mpg. But I mainly do stop and go street driving with my car. Maybe I should turn the o/d off...nahh. Any suggestions, or modifications I could do to get better mpg. I just put a Magnaflow in recently and am going to compare it. Also, those getting more, what was your mpg before you did any modifications to your cars?

To address my mileage problem and also a problem with the heat, I just had the cooling system flushed and a new t-stat installed. Hopefully it will make a difference, but I doubt it since the temp always indicated normal. Keeping my fingers crossed, though.
Thanks for all the input, guys. This board rocks.

just a thought - did yours come stock with 31's? maybe you got bigger tires and that is eating at your gas mileage.
i dont know if it would take it down that much though. well good luck.
