First of all, let me say I am a novice at oil and filter analysis. But upon reviewing these sections in this web, I have noticed that LS1 engines tend to have elevated silicone in both the oil and air filter sections. I have been researching this to try to decide what might be contributing to this. Now my theory: The LS1 engine utilized hypereutectic pistons in the engine. These pistons have a high silicone level. Could this be contributing in any way to silicone levels in oil analysis, or am I way off base and should bo back to the drawing board. I am interested in this because I run and LS1 engine.
