If you don’t like carbon build up you are going to hate the lead bromine that builds up on everything from the high lead content. You can run 100ll, but most us pilots are trying to get away from it, due to it causing issues with all the lead residue deposited throughout the engine.

Castro have a full syn 2t oil called 'GO' or something, it has similar specs to Ultra FB rated, high flash point of 193° etc. But how important is flash point when brought right down diluted with gas. My concern would be the ash content. Problem is we want a mix thats suitable for high rpm saws and then use that same mix in our low rpm blowers. This thread prompted me to clean my blower exhaust port, I usually do it every 6ish months. And always there is a build up of carbon, but not near as bad as the posted pics in this thread, but its there & more than i like to see. I wonder how an ashless boat oil would do made for water cooled 2T's. I run Shell VSX semi FC @40:1. The FD rated Stihl oil called HP-super? was a decent oil (not sure if it was sold in the US), it was semi-synth and burned well. Blowers like BG56/86 will build carbon if not tuned well and run at full throttle. Oil makes a huge difference, were talking under 7500rpm under load so temps are low. I am not sure why Stihl think its a good idea to arm near every customer with a 6-pack of Ultra when buying new equipment for a warranty extension. Its totally not suitable for their blowers to say the least.
Interesting stuff, thank you.

Interesting
on a serious note i believe , use your favorite oil , mix it correctly , use fresh non-ethanol fuel , ethanol free may not apply to all if the fuel is used quickly , most all users will have little to no problems , part of the experience for ME anyway running two stroke products, (soon no doubt to be expired enjoy while you can) is sound , and smell , which for me mean's no matter how excellent the oil is for lubrication , i will not use it if i don't like the smell ....to each there own ...
So whatcha usin’?

What was bouncing around in that cylinder? Chunks of oil?

Looks like the piston
Yup pretty much. The piston and cylinder are spotless underneath all of that flaking off carbon. If it was really thin I wouldn't have thought anything about it, but it was pushing .010 to .015" thick

Hm... I used HP Ultra as a cutting oil yesterday. It worked pretty well.
I use Ultra in FS 130 4-Mixes without problem, and they run 8,500 RPM WFO. Same with BR600s and a BG85. Same mix as my saws at 50:1. I just run them hard.
I don’t know why that much buildup occurred.

Why again do so few people run Husky XP oil? Seems to work great for me.
