Just got my truck so cant put a legit number yet but after my first couple fill ups Ive recorded 14 and 15 mpg.

Not sure what gears...havent checked yet

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!

 

After reading this and with what the old guy gets I will definately put in amsoil front to back. Good air filter to protect the turbo, and an easy flow out the rear.

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.......

 

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?
