best non synthetic two stroke oil??

The idea that synthetics dont protect against corrosion as well as mineral oils is rooted in the fact that many syns are ester based. Esters and castor bases attract water as part of there nature. They are also not very stable in the pressance of water. However,wether or not a lubricant will protect against rust has as much to do with the additive package as the base oil. Formulations with high tbns values will generally protect against corrosion the best. That being said most oil mfgs in the US dont even list the tbn of there oils . I have only seen this done only in europe.

I don't believe MX2T is an Ester based oil, so I think you will be fine.

I think you will find that Mx2t is indeed a ester based oil if you check the msds file for it on mobils site it

I'm not an advocate of making sweeping generalizations like people seem to be looking for in these types of discussions.

Additive packages added to the base oil will ultimately determine the anti-corrosion protection capabilities of an oil. That holds true for mineral and synthetic oils. Pure racing oils are less likely to need or contain large amounts of anti-corrosion additives, while sled and ski specific oils will tend to need more, and snow blowers even more. In short if you are going to use an application specific oil it should match YOUR application.

FWIW - I ran MX2T in an RM150 for a whole season. More often than not when we were finished riding the RM, we'd lean it against a tree at the practice track and go home. So it sat out in the rain and morning dampness most of the time. I never experienced any corrosion related issues with the "Survivor" bike running MX2T (@ 18:1) . Hardly scientific, but an interesting and realistic torture test.

All I can say is CHEVRON 2 cycle is great and @ around $3US a quart!
