Amsoil isn't approved in the 5th generation camaros or corvettes, and I wouldn't use Pennzoil in my Briggs and Stratton engines. Every V8 Camaro and Vette comes with mobil1 from the factory.
I don't think censoring a thread ( or closing it ) because you don't like Mobil1 is the American Way!
I use AMSoil in my '11 V6. If you read the owner's manual where it talks about the oil and warranty you'll notice it says that an equivalent may be used and still be under warranty. AMSoil meets or exceeds that standard so it meets warranty requirements. Silver's comment about Mobil1 tells you his experience with it and uncovers any research or evidence he's found.
Your comment about closing your Mobil1 thread runs just a leeeeetle bit towards inciting. He commented on how many threads there must be about oil and then closed it. He also said in his comment he was closing it.
Sorry about that - but he beat me to it. It is our duty to help keep this forum organized. Occasionally that means merging like threads together, or in the case of yours that had no real comments yet, closing it. So, if that doesn't meet with your approval we apologize all over ourselves, but that's what we have to do.
You'll be able to help save us a little effort along those lines if you'll do a little research by using the Search function instead of starting new threads that have been discussed thoroughly. If you start more don't be surprised if every once in a while they might get merged. That won't mean that you didn't look; it'll just mean that when you looked you weren't able to find it. We don't get paid for our efforts so it's obvious that we do it because we care about this site. Please join us in showing appreciation and respect for all the other members.
One of your posts says you're retired military, and your Eagle avatar suggests that you're a red-blooded, flag-waving Patriot. What was done wasn't anti-American at all. It was simply common sense. If common sense is no longer considered a part of the American Way then that's not a problem. We'll continue using common sense on this site.
Please take a look at your comment and see just how grating it was and why it got a response like this. We have a zero-tolerance policy about calling people names. In the past it was tolerated a little, very little, but as the membership has grown it has also encompassed many more personalities. On the internet some folks (personalities) feel like they're safer because their real identity isn't known so they pop off and stir things up. We're an active site and that just ain't gonna go on no mo'.
It's more than just American to keep things decent - it's elevated to the level of being truly Godly!
