It is laughable to me that you think the 4-ball test is irrelevant. While it does not match the conditions in a 2-cycle engine, it absolutely shows which oils have the highest film strength. Or are you going to make the ridiculous claim that an oil that performs poorly on the 4-ball test will somehow perform better than another in an actual engine? Balderdash!
By the way, figuring out the ingredients is not that simple. The exact Coca-Cola formulation, for example, has been kept secret for more than 150 years.
Those are good points. And amazingly, you managed to make them in a civil manner. You should try that more often. I am not too concerned about using 50:1 with a full synthetic oil for two reasons: 1) narrow molecular weight distribution. 2) Years of doing it with no problems.
I don't think I need to re-tune with my 500i. In fact, I cannot; the microprocessor and sensors do that automatically. High exhaust temperature can also mean the engine is not running efficiently; energy is being lost as heat. But 2-cycle engines are not very efficient anyway. Their main benefit is high power/weight ratio compared to 4-cycle engines.
The 4 ball test doesn't represent much of anything meaningful in a 2 stroke that were worried about, except the lower end bearings, and just about any oil can keep them happy enough.
Again, you clearly don't understand how engines work. High temp engines run more efficiently. Egts indicate many things and are one of the better ways to moniture what's going on inside of the combustion chamber.
Fill out a hurt feelers report.
Clearly doesn't get it.
I am saying Amsoil doesn't have those test engines.. why would they? The don't make oil or additive packages. All they do is call up Lubrizol and tell them what they want to achieve. Lubrizol then sells them a package to be blended with a certain base oil package that is bought from one of the majors.
Coca cola isn't a petroleum product for starters.
Narrow molecular weight distribution is pretty meaningless in a two stroke.
The 4 ball test is completely meaningless in a two stroke, period. It represents no operating condition a two stroke is going to see. In addition any company saying it does is not reputable and is engaging in dirt ball marketing. It also isn't an industry standard test for two cycle oils.
Why are all these guys having so much trouble with oil
Some people are masters of making the simple hard. Use JASO FD oilnof your choice and stop obsessing.
Thats it!
Yet that test does show which oil has a higher film strength. I think that is important for all lubrication purposes.
yet that test does not mimic any of the conditions found inside a 2 stroke engine. It's useless in this application.
Aren't there tests that have been done with saws in the field?
