I didn't know this about newer engine oils.
 

Though the oils have improved over the years, the newer oils can
actually damage your engine.

They pulled the zinc out of oils when engines went to roller
camshafts. Makes me wonder about my 140 Mercruiser (1983) an my 350 GM
(1977)

I suppose I should ahve said they can damage an older engine.

I usually run Havaline 15-40 in just about everything.

Why would you run different oil than called for by the engine
manufacturer?

that's true, John. for the past several years, I've owned Ford
products, and the manual in the Lincoln Mrk VII LSC was the 5.0 (302)
"high output" (H.O.) and the owners manual stated to use Motorcraft
Part #xxxyyzzx int he winter, and part # xxyyzzhhh in the summer, OR
use Havaline 15-40 in the winter, and 20-50 in the summer.

i figured the reason that they recommended the heaver weight oil in
the summer was because they knew people would rod the heck out of 'em,
and the viscosity would hold better in the more extreme internal
engine heat. So, I figure seeing the boats run between 3600 and 4100
RPM, that would be the way to go, so i split the difference seeing the
raw water mercruiser engine thermostat is set at about F.130 degrees.

otherwise, I couldn't tell you, it's just a little quirk of mine I
guess.

BTW, picked my wife up about an hour ago. She's out for the weekend
anyway. Monday she gets some more information on courses of action.

At least she can help with this damn dog!
