anyone using a Manetic oil plug? They sell them for 2 bucks and if it works sounds like a solid investment. Not sure if it has any effects on a rotary.

I bought one a while ago. It just helps gather particles of metals. Its not a bad investment for 2 bux.

 

Rotary engines are made of metal, too.

 

They definitely aren't harmful, but if you change your oil and filter regularly there shouldn't BE any metal for the magnet to catch. Also, you don't want to get a cheap bolt that will easily round and be a PITA to remove. I change the oil every 2000 miles and just threw in a brand new mazda drain plug/oil pan when I got my TII swap done.

 

My co-worker used to be a motorcycle mechanic. High performance motorcycles like KTM that rev over 10,000 rpm come with magnetic oil plugs from the factory. Im sold
