Whether they claim they meet the specs or not, neither Amsoil OR Royal Purple are on the list.
Next- If you follow Amsoil's 25k service interval, you WILL void your warranty. Like I said if the repair is costly enough, GM will request oil change receipts, and an interval that extends beyond the parameters of the OLM will void your warranty.
Before anyone says Magnuson-Moss, that only applies to replacement parts that meet OEM specifications, which Amsoil and RP apparently do not.
This post isn't to bash Amsoil or RP, I just want to play devil's advocate so people know the whole story of what they're getting into, and what the Amsoil sales guys on the board aren't going to tell them. |
...and I will continue to run Amsoil in all my cars without hesitation.
There are some quality oils on the list such as:
Coastal
Pep Boys
Supra Tech
...
If you wish to run those just because they are "on the list" then more power to you.
