I don't like K2 due to the excessive smoke when cold. I often need to start up a cold saw in the garage, otherwise I might not care so much. On another note, I just stopped by the local motorcycle shop and picked up a bottle of Yamalube and Super-M. I then ordered a bottle of Motul 710 off eBay.
Excellent. I'm liking the sounds of that Motul 710 too. It has an ester base, but is a synthetic mix with a lower flashpoint. It might be the ultimate OPE oil. Who knows!
Forget flashpoint! It doesn't tell you anything beyond shipping and storage precautions..
The first list may have some advantages in extreme conditions, but also some downsides when used in a saw.
I am running K2 in my stock 562xp with no smoke. It does smell a little funny. I also have a sneaking suspicion based on a few things that it's less clean than 2R at more than double the price.
The advantages out weight the negatives IMHO.
I get little to no smoke from k2.
Not IMHO. It's really the same argument you used against castor. What good is capability if you never use it and if it comes with down sides?
So far I haven't seen a downside in my saws. No rust, excessive buildup or anything else.
Doesn't mean it doesn't happen.
