I'm just plain confused. Your Si levels were 16 ppm and 15 ppm in your latest UOA's. After how many miles? With what oil? What engine? How many miles on the engine? Any recent work?
I would not call those levels of Si elevated, in general. Most oils contain 6-8-10-12+ ppm Si native. Then most engines have Si materials. Plus no engine is hermetically sealed. Si can enter from other than the AF.
Is there any other evidence to say the Amsoil AF is not performing for you?
Pablo,
This is a 2006 Mitsubishi Eclipse 3.8l GT. It has an Injen cold air intake on it and a EaAU filter installed. Oil fill was Amsoil ASO.
Blackstone has the SI noted as something to watch, mentioned check air filter. One UOA was done at about 25k on the engine and 3,750 on the oil. Had SI 15, Insolubles .6. Second was with about 30k on the eninge and 5k on the oil. SI 16,Insolubles 1.1.
I'm not sure if my filter is give me problems or not. Once I started reading a little more on these air filters, the Amsoil filters seem to be sub-par in filtering effeciency and capacity. That is why I was thikning about chaning filters to another option.
