I have two different questions.
First off, I changed my oil today and cut the oil filter open. I had never done this and was just alittle curious at what they looked like inside. I cut it open and found some red specs in the filter media. What could these be?
Also, I filled my little bottle up for the polaris labs testing. Is this completely free or do I need to send some money in? It says pre-paid on the bottle but I didnt pay anything?
Pics of the specs.
