Hey guys, what kind of fuel mileage are you getting out of your 4.2s. Just filled up today and im at 14.7mpg. I wana know if this is low or just about average. Tuned her up bout mid summer so I think im in the clear on that. Tell me what you think.

 

i think you should search and add on to the 13+ threads we already have on gas mileage. and i can tell you 100% of the other people on here are getting about the same

 

Thanks. I would have done that sooner but i was a bit in a hurry, now i can.

 

i usually get between 14.5 to 15.4....but my truck idles alot and i drive pretty hard best ive gotten on my 08 was 17.9 ... my 02 gets 23.8 with my dad driving it...and 18 with me....

 

I get anywhere from 12 to 23.

 

I got an even 17 on my last tank.

That's straight city driving with a 5 speed.

 

i average about 18 in town and 28 on the highway i have a 5-speed with 3.08 gears...

 

THAT I would like to see some proof of.

 

28 on the highway?????? is it for sale?

 

 

Probably @ 55?

I've gotten 23 but that's at 70+.

Either way, better than the 10 I got with my old 70 with the 302.

 

What's your rpm?

 

We got 19 hwy at 70mpg with a tailwind. Coming back it dropped to 16...

 

the highest I've gotten in my 4.2L V6 with 5-sp and 3.55s are 23 mpg highway granny shifting @ ~1,800rpm doing no faster than 55 mph. with me living in the city stretching every gear and driving like a criminal I'm getting roughly 13-14mpg

that is the last time im posting my fuel results. from now on I'm laying down the law of the search button!!

 

The most I ever got out of my V6 F150 was around 22 mpg using the crappy OEM provided Hankook DynaPro AT (RF08).

With my General Grabber AT2 tires, I'm lucky to see 16 mpg... mostly it is 15 or less.

Luckily... I saved my Kooks for the summer to hopefully get some more miles before I send them to the heap.

I know... those dreaded Hankooks keep haunting me... but heck, why throw away tires that can pass state limit during the summer?!

In fact, I wish people would just give me tires that would pass if they fit on my truck instead of throwing them away.
