Thanks. I'll add it to the database. I did not see a TBN on there. Am I overlooking it? I'm not super familiar with Scheaffer's format. Looks like there are TBN and TAN sections that are blank.Scheaffer Webscope did the analysis. Actually slightly lower Zinc And Moly than Chevron Supreme. Not that it matters, just noticed that.
The elements are mostly in the right ranges and proportions (Ca and Zn are the only ones with >10% difference). I'd say the add pack is about the same, but that doesn't mean they are the same oil.@himemsys Does this appear similar to the Chevron Supreme Synthetic Blend you already have listed?

Yes SP rated. Yes that is the correct oil. Scheaffers webscope focuses on the oxidation number as a measure of when to change so no TBN is included unless asked for.Thanks.

Also, is this SP-rated? Is this the oil in question?

Correct. Chevron Lubtek told me that they are close but the Havoline uses a higher percentage of group 3 in its base oil blend than the Chevron Supreme does. They didn’t say whether it’s 80/20 or 70/30 or what, just that it’s higher.The elements are mostly in the right ranges and proportions (Ca and Zn are the only ones with >10% difference).
