Local oldtimer force mercury mechanic recommended no oil be used in my 86 85 hp Force motor but that which had Lubrizol in oil. Mercury oil or Johnson oils only. I said I was using Pennzoil and he did not like that at all. Crap oil he calls it and any other brand. He went on to describe and draw a picture of the rings around a cylinder and the way carbon builds and how it destroys the motor over time if not gotten rid of and rebuild is necessary. He said the lubrizol in the mecury and johnson oils does not produce the carbon buildup as the cheaper no name brands and name brands oils out there. He strongly recommended those two oils only be used in the motor. I am still using the pennzoil and will till i am done with what i bought. But it makes me wonder. The mechanic has been working on mercury motors dating back to the late
50s. He sounded pretty convincing with his arguments. Any comments?
