I am not going to get into an argument on this subject, because of duratothemax and his sacasm about the people who push Amsoil, and not about the oil itself.
I have run the Amsoil Series 3000 5w-30 in both of my duramaxes since 2003 and also the BMK-17 bypass system on both as well. I just upgraded my 06 with the new design bypass as my old one, well, it seen too many rocks and salt and the fittings were beat up and starting to leak, but at almost 8 years old, not to bad considering it had 350,000 miles on that.
I have not had any oil related issues and had at one point went 100,000 miles without removing the oil pan drain plug, just did an oil analysis at 15,000 mile intervals, and when the results came back all good to go and reuse oil, I changed the bypass filters and filled them up with fresh oil, and then repeat. I never had an oil analysis come back that was not great. I just rolled over 175,000 miles on my 06 this weekend in the snowstorm in Buffalo, and it still runs better than the day I bought it.
I did chicken out last summer and did a full oil change because I was sure that the oil was going to be wore out, but when I sent the sample in, it came back all normal and I wasted $150 on new oil and analysis.
so even for all the nay sayers about Amsoil, that is fine, everyone is entitled to their own opinions about anything, I just wish that people would be more respectful of what some people have to say, and to not make things so personal. Amsoil makes a great product and if the recomendations are followed, the stuff will perform better than you expect it to. It will also save BIG bucks on changing oil that could be better spent on other things for the truck, like better shocks, EFI live, exhaust upgrades, new headlights, whatever.
But until someone steps up and proves that I wasted money or that I was hurting my truck for not changing the oil every 5,000 miles and lining Shells's pockets even more just because they say so, or whatever, I will continue to save moey every 5,000 miles and know 100% for sure that the oils I chose to buy from Amsoil are second to none, and they are also helping to fund my new toy purchase from the money I saved.
Thanks and I approve this message.
You said it!:rofl:
