start your engine from cold (whatever temp you happen to be standing in) 30w
oil. Listen to the sounds you engine makes. notice the difference in sounds
coming from the engine over the next 30 to 60 seconds. shut down your engine
and restart, listening to the sounds.

The sounds you hear first that went away in a minute or so is the sounds made
by engine bearings lacking in pressure oil

Now, do the same with 10w-40 and listen again.

end of report.

Merc doesn't make any oil, it merely repackages it (or more accurately, it
has
it repackaged for them).

Exactly why I wonder if all of the "automobile" advice applies to marine
outboards. This is oil made for the auto industry where the "starting" range
is
0f or below to a normal operating temp of over 210f (what most auto
thermostats
run).
That is an operational range of 200 degrees or so.
Outboards seldom start below 70f and it is closer to 80 most of the time
here.
The thermostat is 120f.

genei, you were told to knock it off and stay out of any discussions with
adults present.

30, 40,and 15W-40.... as you note... 30 will pump at -5F, 40 will pump
at 5F and if you boat at -25F, then 15W-40 is the oil for you.

See, in Jaxworld, water doesn't freeze until some temperature below
-25F and he is still boating. On a moments notice, he needs to start
the engine and pump that oil pressure up quickly so the bearings don't
grind and squeal... or whatever.

I don't know about ya'll, but at 5F, or below, I'm not boating. I'm
pulled up close to the fire, reading a good book, savoring a large
pot of fish stew, and a tall Guiness.....

I still wonder if my Atomic-2 engine would work better, or longer,
if the recommended 10w oil was replaced by 10-30?


10w oil was not the recommended oil, but rather 30w. and yes, it will last
longer if you use 10w-30, unless you start it and run it for hours on end on
end on end on end on end on end on end on end on end on end on end on end on
end on end on end on end on end on end on end on end on end on end on end on
end on end on end on end on end on end on end on end on end on end on end on
end on end...

genie, it is way beyond you. don't even try, unless under the supervision of
some high school kid who knows what a spark plug looks like.

Jax is that your best, most eloquent , and most intelligent response?

My regrets, dood....

Hey Gene -

Is that CW key I see next to the mouse in your computer picture?

And did you ever finish that PA-22?

Later,

Tom

Better known as "Doodles" ..... far more befitting of his maturity and
methodology when responding to most post. It's kinda like he's
"doodling" on the keyboard and not really giving much thought to what
he's saying.

Let's aee now, a guy posts a question about multi-grade oil. From this
we get a couple dozen insulting posts that offer no insight on his
question. Anyone who interacts with jaxasby deserves exactly what they
get. Remember: Do not wrestle with pigs. You both get dirty, but the pig
enjoys it.

And did you ever finish that PA-22?

are you frickin' kidding?

You both get dirty, but the pig
enjoys it.


of course, jood. never let it be said that reality intrudes on you concept of
what is real.

fumb duck.
