As the title say I'm looking to make the switch to Amsoil.

My truck doesn't have an owners manual. :(

I would like to know how much oil I need to buy for the 6.6 diesel?
I already plan on buying their filter also.

Plan on doing everything else also, trans and diff., but that will be done once I install a Trango jr kit.

What else should I be looking to get for my 2500HD?

Thnx!

Here ya go!

Amsoil recommends their Premium API CJ4 5W-40 synthetic; if you sign up through their web site as a "preferred customer" you can buy their products at 'wholesale'. On another thread somebody said they were paying $100 per oil change; I paid $67.20 for a case. You shouldn't need more than 10 quarts. You can also buy it in 1-gallon bottles.

There are a few Amsoil sponsor here, click the vendors link on the top portion above post reply button if you don't have a distributor yet.

I GET THE 2 1/2 JUGS (10 QUARTS) a tad cheaper

Thanks guys. I have bought the oil and the change is next week.

While the jugs are cheaper I went with the case as I'm going to be swapping the filter a couple of times during this run to get all the old oil out so I'll need the extra.

Didn't want to do the flush thing, messy. :)

i just went and had mine done today ii cost me a 100 dollars even, bout 67 for the 2.5 gallon jug and 18 for the filter and 13 dollars for oil disposal, if those dont add up im thinkin off the top of my head

13.00 dollars for oil disposal ,I take mine to autozone 0.00 dollars . I thought if they sell oil they must take back old oil ...... well any how they allways let me dump my 5 gal contaner ,no questions and no charge...

i went and had it done at our line x dealer, there the only place that sells amsoil around here and they changed it. when i changed it using rotella they owuld take it back at no charge.

Mine was free at Orielly
