Sudnley boom only 15 mpg

...the title says it all...i only have bout' 5,900 mi and i drove into a ditch and had to get towed out...after that i seem to be getting worse mpg and i have even started driving like an old lady and no help

 

Get your alignment verified, check your tires for any wear/impact damage, and stop redlining the truck

 

i dont ever redline it...i get close, but this tank its been driving slow and nice. and its been about 600 mi since i got stuck and no noticiable wear. i cant think what it is

 

I'd still get the alignment checked. Even if you don't notice it's out, the tire that took the impact might be shifted slightly, having 3 tires going perfectly straight and the one fighting the rest... causing resistance and bringing your mpg down. It's only about $80 at most shops, if that. Some won't even charge if they don't have to align it.

 

Do you have a skid plate on it? I'm pretty sure, but hate to tell you, but I think something on the underside or something with the tires could be messed up. When they pull vehicles out of ditches, they don't go easy on it. It'll tear the underside of your truck up if they didn't be careful. Best of luck on finding your solution!

 

Also, I doubt there's much if any damage... just saying it'd be worth a try. It could just be rising temp and changes in the fuel. Also, have you been going to the same fuel station, and are you using 91 and good gas (Shell, Cheveron, QT, ect)? I've used costco gas before in my 3000gt and i dropped about 3-4mpg using that crap...

 

well it was AAA that towed me out...im going to measure it agian i just filled up today

 

What where you doing driving into ditches anyway?

 

Good Question-

If it was at any sort of speed or if they were rough at all with the truck pulling it out-It's possible you had a vacuum line or air duct/line fall off etc etc, hurting your MPGs.
The alignment could also be the culprit...Check under the truck to make sure nothing is stuck up there and that everything looks right (Take photos if you aren't sure...)

 

i will when i get done with lacrosse today if its still light out...i think it might be the allingment although i cant feel any pulling to left or right

 

Silverback's Idea is good.


Aliginment could be a problem but so could low tire pressure and bent components. Just had a dodge 1ton in the shop to replace a lower pitman arm slight bend 0 pull but crappy fuel mileage. Owner thought it was an alignment issue.

 

i know its not the exhaust b/c every day i look at it and shake my head how discolored it is from all the rain/mud and i noticed a little bit of rust ont it????

 

well i seem to be getting better today

 

lol... i want exhaust system everyday...but it is something i can live with but hey it will geve me better mpg
