Following on from previous UOA & VOA done, here is another & most likely the last as it is getting quite boring - like nothing has really changed.
UOA for TGMO 0W20 SN/GF5 - 5175kms on oil, E85 use only.
The elevated Copper count I would say is because of the newly installed OEM oil cooler which got completed 3 weeks earlier before this sample was taken.

bluesubie - the elevated Silicon levels are starting to annoy me as new air filters are have no resolve. Would you say this is an acceptable count for Silicone or should I look to dumping the OEM filter & use something else like K&N ? Would appreciate your thoughts.
Cheers
