Why don't you google how they settled their lawsuits. Then ask that question. They are all a SCAM! Well, Lucas, not so much, but their products aren't that great. Additives as stated earlier, if were supposed to be in the oil, they would already be from the beginning.

They all claim to work...

In the case of PTFE (not seen around as much anymore) the teflon particles were actually showm to cause cylinder damage.

Solution? Compnaies filed for chapter 13..

Im changing the oil on my 525 to start the season, I am currently running the M1-302 filter. I purchased a few WIX 51060R filters over the winter to try. I run my boat pretty hard so I thought the "racing" filters might be a better option. The more I read this thread, the more Im am confused on the designation of a "race" filter. Some post read as if I would need to chage filters ever time Im out. I usually do oil changes every 15-20 hours, is this to long an interval with a "racing" filter?

The M-1 302 on a HP 525 is a good match.

If it were an 1500 HP Sterling then I would say to sacrifice flow for filtration.

I have run a Wix R filter for 2 seasons, about 50 hours each, without any trouble using Mobil 1 synthetic oil but I am on a stock 502 Mag, nothing hard core. Held good pressure all season.

Though I would like to hear from an expert if these filters are good for that long.

A Wix R we found out a whle back is essentially a Merc racing Filter. It too is a real good choice and a great price.
