My 2002 Chev Cavalier with 2.4L has an OEM Oil Drain Plug with a magnet at the tip. When I changed my oil yesterday, there was a considerable amount of metal particle residue on the magnet. The car has 20K Km and has run only M1 5-30 after a 1K interval on the factory fill. I'm new to these forums but have learned a lot. I'm now trying the GC and have changed my Orange Can to NAPA Gold. I have the following questions on this magnet thing. Q1. Will the magnet affect my results if I do a UOA, since it holds some metal particles that would otherwise be suspended in the oil. Q2. If there are particles on the magnet, should I be worried about the filtration of my oil filter or the quality of my oil, or is this a normal condition. Your thoughts would be appreciated.
