Also, must the oil be Mercruiser brand? Is there a basic difference between
'marine' and other oils?

yer kidding, right?

kriste on a crutch! no wonder powerboaters stop running their boats by
mid-July. Not only are they broke from fill the fuel tank, but their engines
are worn to shreds by listening to each other.

Multigrade oils do not "thicken up" when they get hot, hotter, or really
hot.

I agree Rob it was a bad turn of phrase & I apologise.... again:-)

The main thing is that in multi grade oils the actual oil (before
additives etc) is the lower of the grades, so it will (deliberately)
stay thinner at lower temps.

As for the rest..... hmmm the way the price of oil is going it won't
matter much soon.

Thanks for the whack behind the ear; I deserved it:-)

I just got overly excited about an on topic post:-)

hey, whoring, it was you who asked to really stupid question, not hoary.

next, you are going to ask if the gas used to cook pancakes at the local IHOP
is different from the gas used to cook pancakes at the house down the street.
(you, of course, being from a lesser class have a electric stove to cook
pancakes to with your Tang.)

If you would re-read the post, you might realize that the comparison was
between marine engines which run about 140-165 degrees and automotive
engines which run 180 degrees and above.

that is also true of single weight oils, but you knew that didn't you (you
being a service manager and all)?




The discussion that you interupted concerns mult-grade oils.

"Marine Oil is boutique oil and can have an additive package tailored
to the marine environment and usage characteristics of the engine.

Given the narrow temperature range that most people's boat engine will
see, any *quality* oil will suffice, if the proper weight is employed
and the oil and filter are changed frequently.

Though not about stern drives or inboard engines, the latest issue of
Trailer Boats Magazine (October) has an article with tests of various
4-stroke outboard oils which are mainly mult-grade oils and compares them to
popular automotive oils.

My thanks to everyone for their thoughts and also thanks for not talking
about Edwards or Bush oil.

Now that I'm thoroughly confused, I'll sift through your suggestions a
few more times.

Wally - don't be confused, just use the recommended oil for the weather you
generally use the boat in and don't put another thought into it! Frankly,
either 30 wt. or 40 wt or a Merc-recommended multi weight, for anything
between 50 and 100 degrees F - I really dont' think it matters
significantly! The lake or ocean water's essentially the same, and the
thermostat you use is essentially the same. Just latch on to a bona-fide
authoritative (e.g. Merc) recommendation, and go with it.

By far, the most important "oil" thing to do is change the oil regularly
and frequently. All the other advantages and disadvantages of mulit vs
straight weight, dino vs. synthetic are so insignificant compared to that.
Yes, they *might* exist, but if so, are very, very (very, very, very) small
compared to just using fresh oil and filters and being good about changing
the oil. You use any of the recommended oil, change it frequently, you
can't do anything better, in a practical sense. Just mho of course, but I'm
right!

why on Earth would anyone believe that? The world

I read the post correctly the first time, and it states (tho *you* may be too
stupid to realize it states such) that marine engines have 140* thermostats
installed.

only if they have no heat exchangers, dood.
