Interesting. The Outboard Shop, the local evinrude/johnson dealer, gave me
the exact opposite recommendation.......

Fact: people forget 50% of what they hear immediatly.
In other words SKip you probablly heard, "bla bla bla recomend bla bla
evenrude bla..."

Further, my manuals for both engines show ........

Gaaaaa you have to comprehend also my selective reader.

I grant you that quadrupling the oil may have some deletorious effects,
but
my common sense tells me........ should not be a problem.

Hey sikp have you been using your BrontoThesaurus again ? Please dont
use such big words as deletorius. They sont have a Salubrious effects
on my comprehension.

Also, I've never seen oil being more subject to explosion/flash than
gasoline.

How does adding oil to fuel make it more volatile?

I think Mr. Grundlach may be correct for once. Adding more oil to a given
amount of gasoline actually acts as an anti-knock ingredient. It lowers the
rate of speed at which the flame front propagates from source of ignition
(spark plug) to cylinder/piston surfaces.

It increases the duration of the burn and thus lowers the temperature of the
burn. Add too much oil and the motor will run as if the choke were on. I
don't know of any cases where piston damage from heat will result. The worst
that will happen is the works (piston rings piston crown) might become
gummed up, the exhaust port will become carboned up and exhaust gass passage
restricted and exhaust port opening retarded because the piston will have to
travel down several millimeters more before it reaches the exhaust port
opening. I have seen exhaust ports so carboned shut that one could barely
poke a finger through it. The engine would not rev up and it performed like
the choke was on all the time.

Too much oil is, indeed, a bad idea but not for the reasons you listed.
