Correct oil

[clint s]

I have a little lifter tap and the guy at the marina told me to try some Mercruiser oil to quiet it down. My manual says to run mecruiser oil or a quality 30 weight oil. It says do not run a multi viscosity oil. I bought some mecruiser oil and noticed it was 25 40. Did I get the right stuff or is all mercruiser oil multi viscocity. It is an 81 120 with a GMC 153.

Might have a look at the Merc FAQ section on Oils.

Never mind, Merc has made it impossible to link to their FAQ.
So just start at the beginning and get to the Merc FAQ on Fuel and Oil recommendations.
