DIC oil monitoring system is not accurate. It might be for conventional, but definitely not Synthetic. I ran 8k on my 2nd to last batch of Mobile 1 EP and my OIL Analyzers report showed a high silicone content. This was do to my K&N air filter ripped against my PCM. I have since replaced that filter with a new AEM dry flow and Ran Mobile 1 EP around 12k and it was time for an oil change based off my OIL ANALYZERS REPORT.
