Hi,
I own a four stroke 2007/2008 Mercury EFI outboard. I know FC-W oils have been discussed extensively here, but in owning my motor I have only used supertech conventional 5w30 or 10w30 oil. I use the motor in Canadian freshwater only. But here is the interesting part: I only use the motor 15-25 hours per season (across all engine speeds, general use) and change the oil and gear lube annually. Would using PCMO really be all that detrimental to the motor with such a short oil change interval?
I have had no problems with this motor (actually a Tohatsu) and it purrs like a kitten on start up. It is my belief that the oil I have used, probably at an HTHS of 3.0 cannot be all that worse at 25 hours of use than an FC-W approved oil at 100 hours. Thoughts/ideas are welcomed! Thank you.
