Oil - Dino vs. Synthetic?
I have a boat with twin 350's, and was speaking with a very seasoned engine mechanic about converting to synthetic oil. I was also considering this change in my Porsche engine, so I asked his advice.
He said the primary advantages of synthetic oils are that they have excellent lubricating properties, and are less prone to breaking down, particularly when comparing multi-weight oils. The drawback however, is that dino oils are far better at suspending particles than synthetic oils. Can anyone shed some light on this? ------------------ Michael '78 911SC Euro |

I don't recall any petro-chemists on this BBS, so take a look at the well-publicized findings of Ed Hackett:
http://www.rconcepts.com/beard/dragnet/drag/oilinfo.html Regarding synthetics, Ed says: "They do not react to combustion and combustion by-products to the extent that the dead dinosaur juice does." Does this mean less contaminants suspended in the oil in the first place? Possibly. Also, a good oil filter should take care of things floating around the oil. ------------------ Doug '81 SC Coupe (aka: "Blue Bomber") Canada West Region PCA members.home.net/zielke/911SC.htm |

I recall the FAA did some research about this subject, the inability of synthetic oils (in this case aircraft version of Mobil 1) to hold contaminates in suspension. Mobil no longer produces a synthetic oil for AC engines for this reason. Remember, AC fuel contains lead and the problem was with lead contamination not being held in suspension and subsequently drained.
