Why are Kendall oils with liquid titanium not dexos approved
I still have two cases of the GT-1 Fulll Synthetic wating to be used. I contacted Kendall to see if it, even though it didn't have the Dexos approval on the bottle, would it meet the Dexos requirements. They sent me a clip from a Kendall executive covering this very topic. He said that the GT-1 5W30 full synthetic would meet the Dexos requirements. I'm going to use it up in the Sierra.
The Kendall exec was guessing of course. I'd say it probably would indeed meet dexos1, but not sure unless all the dexos1 tests were actually performed.
What I think happened is that they originally froze the current Kendall GT-1 Full Synthetic formula back in 2010 right before the dexos1 spec came out, and they never wanted to spend the money for the extra tests-----A business strategy to just market a separate dexos1 oil was then put in place, as they thought consumers would view "dexos1" as "GM-only" anyway, so why not have a separate product just for those people? This was easy to do since Kendall simply bought a pre-certified dexos1-specific additive package from Afton or Lubrizol, or maybe Oronite and blended with their standard class base oils to get the final product, already dexos1 approved and ready-to-go, but without the titanium Kendall had in their own custom brand product.
If you don't use a dexos1 officially approved oil in a post-2010 GM vehicle, then your warranty coverage for engine damage might be in trouble. Some risk.
Thanks for your response. I do understand the risks. He might have been guessing but since he put it writing for all to see along with the liability to go along with, I'm going for it. I only do 5k OCI's anyway so I'm not overly concerned about any damage. I would also refer you to TiredTrucker who has a Dexos1 required vehicle that only uses 10W30 (none are Dexos1 approved that I know of) in it with no problems and he's been doing this since it was new. TiredTrucker, please correct me if I'm wrong. Again, not arguing with you and I understand what your saying. If anything does go wrong because of my decision, It will be a lesson learned and a study in what not to do.
