- You should always compare VOA to VOA. For the best UOA interpretation, a VOA should be submitted at the same time.
- Slight variations between oil batches
- Lab error
- Different residual oil from previous fill skewing results
- The Amsoil bypass filter is too effective and is removing additives
Although they differ, you can still assume Rotocraft230 is using the newer CK4 product with lower calcium and higher magnesium. By the way this product is not rated as SN, and is bad news for catalytic convertors (as if he still has cats).
If I’m interpreting Dave1027’s question correctly, he’s actually wondering why the additive levels in the CJ-4 uoa in the OP are different than the additive levels in the CJ-4 version in the VOA. Or did you know that?
