First Oil Change - Basic Questions

[darkonion]

Performing my first oil change on my Duramax this weekend.
Going with AMSOIL 15-40 AMETP-EA and Oil Filter. Getting it locally for a good price.

Do people generally go 10k or 15k between oil changes with this product? Most I've ever gone on any vehicle has been 5k, so this is new to me.

I've also seen it mentioned about the Allison Spin-On (Tranny Filter). How often does this need to be changed and is it a simple change? I'm hoping if its a simple change that I don't need to change the tranny fluid as well.

Any other regular changes I need to be aware of? The fuel filter was changed about 4k miles ago so I should be good on that. I'm planning on doing an upgrade to that as well in the near future.

I'll be going 10k between changes when I switch to Amsoil next weekend, but idk what everyone else does. And for the Allison Spin-On external filter, change it every 10,000 and you do not need to change the tranny fluid every time. It's really simple, just unscrew the little red filter underneath your truck by the trans pan, clean off the magnet, put it back and screw in the new filter

It depends on how my driving style is for that time period but I change no sooner than 10k no later than 15k.

Amsoil in gas engines can go 10k. In any diesel no way 10-15k. Way too much fuel contamination that breaks down the oil. 3-5k on conventional. 5k-7k max on Amsoil even.

Awesome, sounds simple. Does it leak a lot when you take the filter off? I imagine it will need to be topped off.

you would prolly be fine with 10,000 at the most but if your like me i like to keep my oil clean so i usually change mine 2 to 3 thounsand miles sooner than recommended also when change oil wouldnt hurt to check the other fluids and air intake filter while hood is up.. oh i highly recommend the fumoto valve from merchant automotive

it leaks some, but not a lot. Depending on how your ATF level is you may or may not need to top it off.. Probably only lose about 8 ounces give or take. My current level is toward the high end of the normal range so I expect a top-off will not be needed on my next filter change.

Yup, already ordered the valve a while ago. Will make things so much easier.
I have a K&N Air filter that I just cleaned 2 weekends ago. Will check other fluids this weekend.

I do 15K mile changes with the same oil you are going to use. I change my fuel filter and Allison spin-on filter all at the same time. It makes maint really easy. Do not forget the magnet on the Allison Spin-on filter. The Allison spin-on filter is the same as the oil filter just unscrew and replace with a new filter. I would use that fuel filter until the next oil change then change it and get on the same program like I do. Do not forget to grease the zerks in the front end.

With the right setup you can go more then 15k on amsoil(i believe up to 25k) as long as your getting it tested , do some research on it. Changing oil at 3k miles for any DD car/truck is a waste of money. Its an a old truth... Oil is way better then it used to be to require 3k changes

Edit: I belive its if you have the DPF and EGR gone helps to improve that extened drain period
