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.

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.
