Re: Oil Scare - Universal M25

Same grade of oil (15W-40) different brand (Motorcraft, from WalMart). Electric gauge - but I believe that it is working. I think that the issue is that the oil was mis-labeled.

Also, forgot to mention that the Oil breather was blowing a fair amount of gas (air), and a little bit of oil out of the engine when the oil pressure was low, and RPMs high. This made me think excessive blow by - caused by the wrong grade of oil.

Also, also, I checked the oil pressure relief valve while I had the oil out of the crankcase, on the theory that it may have been stuck open - it wasn't.

Low RPMs is still a puzzle though. Great idea about the air restriction!!... I will definitely check that out on my next trip to the boat.
