Trust me, V10 owners don't need reminding about how bad our gas mileage is. 8-11 here.

 

But hey, on the plus side, it's a FREAKIN' V10! I get about 12-13 in my 1500 with a 5.2. Sometimes I wish I had purchased a 2500 with a V10, and had similar mileage with gobs more power.

 

Yeah, easy tire-smokin' burnouts tend to wash away the bad gas mileage taste.

 

That's weird, my truck tends to be gutless and slow, and it can only break traction when going around a turn or when it's wet.

 

Something wrong there. I can break my tires loose at will. I have to be careful not to give it too much gas in the turns or I'll spin them.

 

i get 6 gallons to the mile, but i also have an umbilical cord attached to my truck from the gas station

 

Your truck also has 4.10's. If he has 3.55's that's a big difference, and maybe his truck has a ton of miles or hasn't been maintained properly? I think you're right though, he may have a problem, a V10 should be able to break the tires loose regardless of gearing.

 

I also have 4.10's, but I bought the truck used and clearly, it has some miles on it. Right now, it's at 122,xxx. It seems like it could have been taken care of much better, too. Any idea what my problem might be? It's really sluggish, I can mash the gas and it just crawls. I have a lot of trouble even getting it to break traction.

 

You could need a serious tune up. You may need to check fuel pressure as your pump may be getting weak. You may just have an engine that was beat on for those 122k miles and it is tired and in need of a rebuild. Basically thee are so many possibilities that it would be hard for someone to diagnose over the internet.

 

I would suggest a leak down test, or, at a minimum, a cylinder compression test. If any cylinders are beyond 10% difference, that's your answer.
