But as far as lubrication to the crank, bearings and piston/cylinder wall, there will be no issue?
The Shop
FWIW, I ran Maxima Super M and K2, Lucas, and Yamalube in my '04 KX 125. In two years, I never fouled a plug. I switched to Klotz and had my first fouled plug (on start up) shortly after.
In your expert opinion, if the OP continues using 10/40 premix, what will be the mode of engine failure?
And, where in the actual fuck, would 'sludge' accumulate in a 2 stroke?
I don't think you have any good answers but are offended because someone is operating outside your orthodoxy
This is a non-issue.
Where will the sludge accumulate?
In the power valves.
In the entire exhaust tract, from the spark plug all the way to the tip of the silencer.
Backward from there, to the engine-side of the reed valves.
On the top of the piston.
Also, and more importantly, the film strength of a 10W-40 will be inferior when mixed with gasoline. Anyone using it as premix runs the risk of metal-to-metal contact anywhere that the oil lubricates. Piston seizure is the most likely mode of engine failure in this scenario, although it could be wrist pin seizure or bottom-end bearing failure as well. Should I continue?
I don't think Moto Tribology is offended and neither am I. However. two-stroke oils are far better as premix than four-stroke oils; they have been engineered and blended to do that specific job. You would be equally remiss to use chain lube as engine oil in your 4-stroke for all the same reasons; it isn't designed to do that job, even though "oil is oil."
The mode of failure? Probably excessive wear, but it's not like one thing happens and it is all done. It is a cascade of failure brought on by the route cause of the oil not burning off as it should.
4-Stroke oil is not designed to burn like 2-stroke oils are. The aha moment in the development of 2-stroke specific oils was the realization that it didn't need to stick around; it could be designed to get in, do the job, and get out leaving minimal material behind in the process.
And friend, I'm not offended and didn't really mean to offend. I'm just trying to help and make a little light of the subject along the way; my apologies if it tickled you the wrong way.
Big risk of engine seizure? Lol
I’m done for the day here. For some reason people got hundreds of hours on their motors when they ran Motor oils before there was “2 stroke oil”. without all this metal-metal, seizing of motors...
LOL I love how both “experts” above me chimed in with completely different answers.
The point is, the 10W-40 will NOT run cleaner than a good, synthetic 2-stroke premix oil.

But hey, I'm not a mechanic. Hell I'm not even an oil formulator anymore, so feel free to take my comments for whatever you think they're worth.
P.S. I've seen some chain lubes in my day that would probably have made some pretty decent 2T oils
The residues left behind will be the biggest problem over time and all that comes with that (which then makes it a lubrication issue).
How much time you say? Hahaha good luck trying to predict that. Best answer I could give....it depends.
Cooking oil worked great on air filters also.
Oil companies do certainly advertise to maximize their profits, but they are also making oils which truly are different for different applications. It's why you rarely ever hear of "Oil-related engine failure" anymore.
