I was reading a mercruiser repair manual I have and it says sae40. My problem is i dont think I have ever seen straight 40 in any stores around here. One of the local boat shops told me they just put that 20-50 in every one they service, but I think they are servicing mostly newer mercruiser stuff.

when i bought the boat, ive got a sheet on just what the motors were dynod at and i wanna say it was 466, not to sure i say that because i could either by the boat with prochargers or without and i no with the pg it dynoed at 647hp and i chose not to put them on the boat because of longer life.

There have been huge discussions on this topic.
Search "best oil"
After thousands of hours of lab and real world testing...
The general consensus is that Mobil 1, V-twin, in 20-50 or Amsoil are the best two oils to use.
