Dad has a 2003 duramax. yeah i know we are talkin dodge. same mileage everyone here is talking about. Now he is at 25mgp highway 75. He only did 3 things. Just a brand of air filter the chevy garage recommended. Plane ol filter. Brought the exhaust size up to what I believe the dodges come with. And amsoils the entire rig.
He has a topper on the back, but he always had that.
If you change that configuration, that mpg is avg. for example, a trailer, or his pickup camper.
I've hear about royal purple oil. It's just such a girly name. Amsoil feels more macho. haha!
So what I'm wondering.....
Anyone change over to amsoil get any increase on the highway?
What am I really getting with a chip? More hp = more gas = more $$ right?
One last thing I'm thinking of, someone told me k&n is hard on turbo's because they aren't the best filter.
Anyhow....I can't wait to check out my new 2006 mega cab tomorrow! yeah baby!

I don't think I will get a chip, treat the 30 grand rig good. too expensive of a machine for me to be hot roddin it around......well......maybe just once to see what it can do....and one more time if my buddy is with me......but then again I want to smoke dad's old chev.....well then winter will come and it's just so much fun to slide around in 4x4.....dirt roads are fun too though....that's it...just 5 times....then grandpa drivin for me.....
ya know the kids think it's funny when the rear wheels lite up.......

![Question](https://dodgeforum.com/forum/images/icons/icon5.gif)
I have a 1997 Ram 2500 12 valve 5.9L engine 4x4, extended cab,410 gear ratio with 402,000 miles riding on stock LT245/75r 16's load range E@ 80 psi. I never seem to get much better than 13mpg towing trailers. I often weigh in at 20,000 + lbs on the landfill scales. Is that about as good as I can expect would an S&B air intake provide much benefit?
