A virgin oil analysis shows a rate of 66 for OXI and 57 for SUL. Anybody can tell me why this numbers are so high for a virgin oil. I asked Amsoil and they gave me that answer but my english is not dood enough (I'm french) to really understand their answer. ''The FTIR scan reads oxidation and nitration at the same wavelength as certain esters give a false high reading. This phenomenum only occurs with synthetic oils and not petroleum. We suggest using a lab that is experienced with testing synthetic oil.'' Thanks

What they are saying is basically doing a generic low cost oxidation and nitration test on many synthetic oils - especially in the virgin state is pointless and makes little sense.
