well stop pouring me so damn many drinks! i'm gonna drink it if it's right in front of me, duhhhh

 

This was my understanding as well.

M1 0W40 is still a very good oil for the LS1. Might not have the longevity of the GC 0W30, but it's a great second choice.

M1 5W40 is out of the question for me, just like GC 0W30. Can't get either locally, and I'm not about to order oil on-line.

 

There is no such thing as "regular Mobil 1." It's either "Mobil", which is either conventional/blend, or it is "Mobil 1", which is synthetic. I think alot of people get confused on this.

 

yea man, this is correct.

15,000 mile mobil 1. it's synthetic. looks like i might me right after all. i owe my memory an apology

 

u owe it more then that

 

you're right. a beer isn't helping my memory is it

 

My bad, you are correct. I was also confusing the 5000 mile Mobil with the 15,000 mile Mobil 1 synthetic.


I'm curious what the rating is for the 15,000 mile and if the 0-40 actually is a changed formula. I'll be using Amsoil on my next change anyhow though.
