Got my used oil analysis from Oil Analyzers Inc. I figured itd be easy to get the prepaid thing when I got my Amsoil. Next time though Ill send it to Blackstone Labs, their reports look much better. Things are looking good. Ill have to include a copy of this one with my next sample to Blackstone so they can have a reference. Wonder how it will be after running Amsoil for 7.5K? I changed my intake and drove cross country so Im thinking that may why I have some Silicon? Not much though. Ran this oil (Syntec 5w-30) for 7680 miles and I have 42012 total mi. at time of test. No complaints, not burning a drop of oil
