TCW III oil test results

[Team_Dougherty]

The much anticipated TCW III test results are back.

Follow this link to see.

From my interpretation of the results, they are all pretty much the same stuff, 20W oil and dye. The only minor difference is the Mercury and Yamaha sample had molybdenum in them.

Take these results and do what you like. I will stick to supertech.

Now, what is that text suppose to prove?  That's nothing but an oil viscosity and contamintion test.  Same test I used every three months for some 500 gallon hydraulic tanks for some giant presses at a plant I was at.

At least I'm glad to know the brand new oils we buy are not full of all kinds of harmful contaminats.

Look, I'm very glad you're happy with you Supetech oil.  If you manage to get several hundred hours on your motor, I'm sure you're mechanic is going to be very happy you used your Supertech also.  

Nothing test oils like operating conditions.  That's why New York City taxi cabs have always been a great testing lab for most major brands of motor oil.  For me, I'm just going to keep paying my $22 a gallon, soon to be $32 a gallon if things keep going up like they are.  I've seen bunches of motors with cheap oil, I've seen bunches of motors with good oil, I'll keep right on using the good oil.

However, you could look at it like this, figure a big V6 burns about 1 gallon of oil every four hours.  Figure you pay $17 less for oil than I do.  If you can get 500 hours out of you motor, you saved about $2000 to pay your mechanic.  Since it only cost about $4,000 to have a big V6 rebuilt, you get your rebuild at half price.  Of course now if you go with factory remaned power heads, they are about $6000+  so the saving aren't so great.

When they said there is "no insolubles found".  doesn't that mean there was nothing else there other than oil and the stuff they found?

I think "additives were scant" means anything else added was very little and of no help to anything.

ya im sticking with supertech i used that all last weekend and did not have a problem with it.

When I read about people talking about carbon build up I wonder if it is the molybdenum in some of the oils. I am not a chemist but that is pretty tough stuff. Read The link I posted about it in the results. Perhaps it does not burn completely during combustion and that is the gunk that builds up in the motor. The stuff melts at 4753 °F and Boils at 8382 °F I do not think the motors get that hot in the combustion chamber or hot enough to keep it vaporized until it leaves the exhaust. The combustion process may be hot enough to burn the gas and oil off and leave the molybdenum behind. Perhaps that is why Mercury sell there quick clean stuff.

We'll never know.

Calcium and Magnesium are detergents

Zinc compounds are anti wear agents

This is pure speculation on my part, but here goes.

At 1069 ppm (molybdenum) it's barely enough residue in the carbon build up to prove that you were, or were not using TCW-3 oil in your outboard when it failed...  maybe it's there because it will survive combustion... and they can use it to determine warranty.  ?

[Al Wolbach]

My outboard cost approximately $18,000. Amsoil is about $23 a gallon. I just don't see the need to gamble for the few dollars savings......................Al      Even a 9.9 HP cost more than I care to gamble.

here is a easier list to read what is in the oil and what it does
