As far as warranty, there are some things to ponder. Firstly, there are specific criteria that apply to Signature long drain interval, such as 25000 miles, 700 hrs or 1 year - whichever comes FIRST. This also stipulates using Amsoil special filter, without which the oil is only good for 12000 miles. So this is not just about the oil but also about the filter! Aha! Lastly, the type of usage conditions can shorten the drain interval as specified in the tech sheet. As far as any warranty claims, one MUST start the process by submitting a min of 9 ounces of recovered oil. Now if anyone has seen a motor grenade on a race track, one will observe that most if not all of it ends up being puked on a track surface. In either case, it is worth to read the Warranty legal page in detail. It is also worth reading GM warranty legal page in detail. Enough said... Amsoil tech sheets provide some specs, but not all. For example SAPS are omitted, but looking at Total Base Numbers i would deduct they might be on a higher side? Just a speculation here. Also, looking at the available 5w30 specs i would much prefer to use Mobil1 ESP Formula 0W40 or Valvoline MST 5W40 (both Dexos2) as their critical HTHS and Flash points are much higher, while SAPS appear much lower. The only aspect where they trail Amsoil 5w30 is NOACK but that's neither here or there, as they are not extended drain interval oils and need to be changed more frequently anyway. Lastly, no 5w30 is warrantied for track duty regarding lt1/lt4 cars. So what Amsoil recommends for LT1/LT4 engines does not apply to track use. Just an FYI here. |

Has anyone tried the Amsoil European Spec 5W40? The website shows it as being GM Dexos 2 certified. Obviously the viscosity is different and one would have to consider the climate and driving style.

Note this oil does not come up as specifically recommended for Camaro on Amsoil website. Only specific 5w30 Amsoil oils come up. Anyone's guess as to why, as 0w40 and 5w40 (Dexos2) grades have been recommended by GM from day one, some 4 yrs now yet for some reason they dont come up as officially recommended on Amsoil website. |

Hello, My first post here and looking forward to learning from you guys. Bought a 2018 1SS M6 with 20,000 on it in May. I'm now at 30% oil life and use the car for street use only. Was getting ready to plan my oil change and really wanted to use Amsoil 5w30 signature series. But reading this post I might just have to dealer change my oil. I plan on keeping my car a long time so was wanting the best oil out there. I thought that was Amsoil. I attached a link and Amsoil is not listed as an approved oil. Sorry, I know this subject has been beat to death. |

I think it's tough to go wrong with Amsoil Signature; if they don't have the factory approval, they're probably working on it. Many oils, depending on application, exceed the various approvals. I've run Amsoil products in the vehicles for which they're highly rated and approved (Blazer, 80 MB Diesel), and will run the 0W40 in my 22 2SS 1LE. The Mobil1 approved oil is also probably every bit as good as the nearest oil in the Mobil1 line, 0W40 FS, which I've run in the past in Porsches (it carries many Euro factory approvals).

Tons of opinions and often times folks swear on a particular brand. But, here is a story fyi: Valvoline MST 5w40 used to be Dexos2 approved and many folks used it, myself included.
Then, Valvoline changed a recipe to cater to Euro engines (if my memory serves me right) and its Dexos2 got dropped. Many thought it was still good for our Camaros, but an owner who happened to work for them chimed in and recommended folks stay AWAY from it. So there you go. Want to take guessing out of the equation: use what the manual recommends. Lots of excellent choices on the list imo. And, don't run it until the system shows 0% life left, as that defies any logic of worrying about a quality of oil whatsoever. Happy motoring and cheers! |

Thanks for your response. I respect your opinion. I was planning on changing it around 15-20% oil life. As far as Amsoil goes I'll continue to do more research but may end up letting the dealer change my oil. Thanks! |

I change not too far beyond 50%, but that's conservative. Fyi Ive been running Motul 5w40 Dexos2 since Valvoline MST lost the certificate. But, also had a few Mobil1 Formula 0W40 fills at a dealer. Anyhow, enjoy your car - they are amazing machines! Cheers!

It looks like Mobil1 0W-40 is kind of hard to find. I use Amsoil Signature in my other vehicles and I order everything straight from Amsoil.
