that's beyond ridiculous, if we are referring to major brands and not "sleazy convenience store oil" - Pennzoil, Mobil, Castrol, Quaker State, Valvoline, etc. are filtered to a crazy degree, my bottled spring water I am drinking right now likely has more particulate than these high line oils, and used motor oil does by many times over. In fact, it is particulate that is responsible for most of the opacity and dark color of used oil. Black carbon is a particulate!
So the sae papers dnewton derives his data from is rediculous.
I'll explain it to you so you can understand.
Oil puts its own anti-wear layer on over time. When you change your oil the new oil strips the previous anti-wear layer off and puts on its own,so during that period wear metals increase. It's not "rediculous",its proven,to automotive engineers anyways.
So if you consider yourself to know more then by all means educate me. Until such time I'll consider your posts rediculous,and posted by a blowhard bitog know it all,who has no data.
Not trying to sound sarcastic but if this is true, which I will not dare Q?, then why don't we just keep using dirty (used) oil?
And, while on the subject, if a filters media is "supposed" to filter better as it gets used, why "even" change our oil filters?
The oil layer theory makes sense to me, in a way. But, if a filter gets better as it's used, how used will it get before it goes into bypass? Why not just avoid the bypass guessing game and just change it at every OCI?
I am going to change it no matter what, but others might be curious and want to know.
