Standish211

Hi there, my truck gets poor gas mileage it is about 13mpg. I was thinking a V6 should get at least 17mpg. It has new plugs, wires, air filter, new gas filter, standard tires runs well & no codes. It is a F150 Reg. Cab, long bed, V6 4.2L, Auto.

Can anyone help me?

Thank you, Mike

cai, and exhaust i think helps with mpg



or upgrade to the 4.6 ive been told by several people that the best motor mpg wise in a truck is the smaller v8

Ty

your problem is that you have a big truck with a little motor....

I'm in the same boat as you, but mines a supercab. Takes alot of oommpph to move a full size truck. Quit checking your mileage, you'll only be disappointed.

Mike, that does sound a bit low. I get 12-17mpg outta my 2002 5.4l with 147k miles on it. Have you checked the air filter and/or fuel filter?

Also, how do you drive? Heavy on the pedal?

Hi there, New Air Filter & Gas Filter. I drive pretty mellow not heavy on the pedal at all.

Thanks F150Dan.

Dont recommend "upgrading" if you havent performed an engine swap.

I have a 2003 F150 supercrew with the 4.6 and generally get 16.5 to 17 mpg, but since the cold has hit it appears to have dropped to around 13.5, I wouldn't think
it would drop that much even with running a bit richer during the extended warmup.
Thinking of going with a K&N air filter.

I have a 2003 supercrew (4.6 2wd)that generally gets 17 but with the cold weather it has dropped to around 13.5.
I'm looking at a K&N air filter for everyday driving.
Anyone else having poor cold weather mileage?
