Why? There is a guy on here that has milled with it plenty in his ported saws? 0 issues
Di-ester... not disaster... it should work decent in a milling application..
Another dirty little secret of mine.. I'll run Klotz Super Techniplate at times in my mx bike just because I like the way it smells..
 
Here is a thought for all to ponder..
Regardless of which oil used carb tuning is crucial to the performance and longevity of the motor. It's foolish to worry about oil till you have that nailed down as any JASO-FD or ISO- EGD oil will do.

lol!! Ok sorry
 
Looks to me like that saw was WAY over heated, more than a function of the oil. I would have to see more evidence, more examples, before I'd say that was the oil.
That's pretty indicative of castor oil not ran at high enough temps. Seen it many times. When it's heated up castor polymerization instead of.combusting cleanly.
 
800 is a double ester too....is that why they have the highest flashpoint?
Typically the synthetic components of two cycle oils are PIB or various different sorts of esters. Di esters are certainly no better that polyol-ester or carboxylic esters. Probably the finest ester based oil I have seen was mx2t which was a carboxylic ester. Mobil always had a leg up on the small guys because they actually design and make the esters then market them to the smaller guys. Of course they keep the best proprietary for themselves.

Gack...!!
I can still taste that stuff...
I'm thinking 32:1 might have been too much for that application...
But we didn't know that...

Stuff just smells fast.. and if I jet to the edge the and keep the load up it burns clean enough that the piston doesn't too bad. The exhaust valves however get filthy very fast.
