My 1st two OC's we're casrol semi syn, next two with PP, last 2 and currently Amsoil ASL 5w30.Has anyone tried the amsoil XL 10w30. And is it on GM's approved list? I have a '06 Chevy Silverado with the 4.8 v8, It's a butter smooth running engine. the PP was the only one that used a 1/2 qt. on 5k oci's.I'm asking because i have a 100k ext warr. and i want to switch and stick with one product and not have any warr. issues.

I used to use the Amsoil 10w-30 in my 2001 Tahoe with the 5.3L. The book calls for 5w-30 but I thought since I was in Atlanta the thicker oil would help with heat. The truck would burn a half quart over the 7,500 mile OCI. When I changed to 5w-30 it does not use any oil now. The truck has 102,200 on the odometer and runs like a champ. I am currently running RedLine 5w-30. I have never used the Amsoil XL oil, just the regular ASL. In my opinion, stick with the 5w-30 and a good fully synthetic oil. I use RedLine or Amsoil. Oil is cheap, engines are not.
I also use a FilterMag on the oil filter. Every little bit helps. www.filtermag.com

That's because Amsoil does not partake in the program -- not because their oil is inferior.
Keep using the ASL
Never used their XL oil before but I do use their 100% synthetic oil. It's pretty good stuff.
Is the XL a synthetic blend?
I think that the premium synthetics can easily achieve 7,500 miles if you have a healthy engine with a good air/oil filter.

Then please explain yourself a little better when leaving such "incomplete" info in your reply. First impressions by most that read such a reply is failure to pass the GM specs.

CoJam,
You won't have any warranty issues, as all of the Amsoil 0/5/10w-30 oils (XL, TSO, ASL, & ATM) are recommended for applications requiring the GM 4718M & 6094M specification.
Approval list doesn't prove that the oil is better, it just proves that the company paid for GM's certification.

As someone who had a 4800 engine in my 2000 Silverado and did quite a few UOAs, the best UOA was with Chevron 5w-30 and Pennzoil 5w-30.
My Moms 2002 truck with the same engine is doing great using mostly QS 5w-30.
Go over to the UOA section and do a search on 5.3l (same engine shorter stroke) and 4.8l and see what oils people have posted UOAs on.
Then get one done and see how you compare. What runs great in one persons engine may be different in yours.
What does your warranty state for a OCI? Thats what I would follow to see what oil I used.
Take care, bill
PS: I agree with having to pay to get on someones list. BUT, if you have a warranty you will have to make sure you are following the rules.

I think it is as well. Could you imagine how many millions of dollars that Mobil has made since they've made Mobil 1 synthetic the factory fill in the Corvette since the mid-90's?
Because of that, some guys think it's the one and only oil in the world to use.
ExxonMobil has made a bundle of money over the past 12 years, but not much of it because Mobil 1 was made the factory fill (because it solved an engineering problem). Lubricating oil is a relatively tiny part of the company, and the synthetic is a relatively small part of the lubricants portion.
Mobil spent a bundle of cash on advertising for about 20 years, trying to build a market and demand for synthetic oil. It seems to have worked reasonably well.
