Synthetic Oil?
Jeff,
I haven't specifically talked with him about synthetics, but there was a post a while back from a guy who had used synthetic oil in his 5.7L Merc and had some kind of premature failure. The subject was " Mercruiser Motor Failures" from Feb 2003. You might want to search for it on Google and read his post. Also, if Mercury specifically doesn't recommend something I'd think it is likely because they've seen some problems, and not because they just haven't tested it. YMMV, Don W. Messing In Boats wrote: That's why I stuck out my timetable so far; I figure I will have this and a lot of other things figured out by then and will know what I should have done. I am hoping for 2000 hours though. I change every 100 hours and run the boat at hull speed, about 1800 rpm, which I believe to be a lot kinder to it than up on plane at 36-3900 as it was designed for. What does your buddy say about synthetics? Jeff |

Synthetic Oil?
I think your chain has been stretched.

Back in the mid 90's, my brother bought a new Jeep Grand Cherokee and used syn oil in it at first. He claimed that the engine wouldn't heat up enough with syn oil to give him much heat from the heater. He switched to dino oil and everything was just fine. Was he tugging my chain, or has anyone ever heard of this phenomenon? cheers oz |
