We Need an Oil Additive Thread

[SCWSpyder]

Thank you all! I believe I shall refrain from additives. But isn’t the Petron engine-running-less-oilpan is kind of impressive?

Not sure where you are headed with your comment. I purposely refrained from technical info in my post you quoted. Since you brought up the terms Lubrication and Slipperyness, which you may find is technically lubricity, but I may be wrong on that, and you are an a dealer for Amsoil products, i yield the floor and ask that you explain the subject matter you brought up.

I have done a lot with oil. But I do not consider myself to be an expert! As with any advise you get here, including mine. You apply it at your own risk!

Getting technical with all of this just puts people to sleep! But you have 2 actions going on with any lubricant.

1- The ability to keep moving parts separated. For example; ideally, the gear teeth, spinning bearing parts (whether they be solid, ball, needle, etc.), will never actually touch. One gear tooth transfers energy to the lubricant in between the 2 teeth, which, in turn, transfers that energy to the driven gear, without any metal to metal contact. When you consider the pressures involved, it is a bit mind boggling!

2- The amount of 'Friction' or drag produced in accomplishing task #1.

It is my understanding that 'Lubricity' encompasses both.

But I think the real take-a-way in this thread (which I consider to be a very valid subject). Is that though some oil additives might be a good idea in some situations for a single service application (like an engine only car, truck, lawnmower, etc.). In a multiple service application where you have an engine, transmission and clutch sharing the same lubricant. Additives are usually, if not always, a very bad idea.

If this tread saves just 1 owner the grief of finding this out the hard way. I say that it was well worth the discussion! :thumbup:

I step away. After reading his post, it seems every oil containing moly is acceptable, he can explain more.

Myself, I will continue using Mobil 1 10w40 Racing motorcycle oil with no additional additives.

And frankly, you have made a good choice.
For the record I did not say every oil containing moly is OK.
But, there are a couple dozen MC oils that contain moly, they do not cause a problem. The majority of clutch slip problems are worn out plates, glazed and overheated, and sacked out clutch springs. Changing to a different oil puts them over the edge, and suddenly the lubricant is to blame.
You want zero moly? Valvoline synthetic MC. Honda HP4, several diesel oils.
Lots of folks here use AmSoil. You can check your self, but it has just about 40ppm of moly.
Your Mobil Racing 4T? About 75ppm of moly.
Very hard to say moly is the cause of clutch slip problems when majors add it to their premium offerings.
In conservative amounts, moly benefits cams and gearsets, while not upsetting the clutch.
Pick an MA rated oil, in the right viscosity and ride. Change it every once in a while. Ride some more.
You'll get more problems long run by having an oil past it's prime, sheared to a 20 weight, than with a splash of moly.
Your next post says you follow 540 RAT blog. Dive deep into that, he has many comments on moly and wet clutch.
