Great! appreciate the info! I looked it up online and Amsoil sell a "Marine" engine oil, but, its 10W30 they claim it will replace the Merc oil, which I think is 25W40 or 25W50? The other oil they list that appears to be geared toward Diesel/Marine engines and its 15W40. I didnt see any "Marine" 15W50? Is it Marine or Automotive oil?
I guess what I am asking is what would work best in my 96 454EFI, Its no rocket or anything, but, I would like something that extends longevity and I have had great luck with synthetics in the past, Thanks!

The big reason was that the levels of zinc/phosphours were substantially higher in motorcycle specfic than over the counter engine oil.
Zinc is an anti-wear additive and over the past 5-6years the oil manufactures have been dropping the levels of zinc.
They started in the 1200-1400 parts per million range and are now down to the 1000 ppm tange, soon to be dropped to the 600-800 range. If an oil is going to be licensced by the API, these are the latest anti-wear levels
Google "Spectro Motorguard" good info.
If you can't find Motorguard, I don't think you will, go to a motorcycle shop and purchase Spectro 4 20w50. Tons of anti-wear.
Hell call them, they have a toll free number.
