I've got threads on here with work saws worked hard not babied with a couple of thousand hrs on em still running run only on Active, the Garden is good oil also but only run it a few years.
He got paid enough to build a buzzsaw to help speed up make it easier cutting his next sleeper order ya have to start somewhere and slowly work ya way up.

Okie from Stigler doesn’t have much of a ring to it
Yeah the 1st generation "Ultra"was introduced for 4mix trimmers & blowers not chainsaws ! It was for air cooled 4mix engines & was a basic FB rated oil . The new "Ultra HP" as some refer to it is a full FD certified oil much more suitable for saw applications . I refer to the new Stihl oil as "HP Super" I do not buy anything "Stihl" however have heard horror story's from some very knowledgible people of the pros & cons of Stihl 4Mix oils brother !
Lots of carbon , though I have seen much worse .
Ran castor in race sleds for yrs when it was the rage & only oil that prevented galling or complete seizure in fully modified race sleds , it was dirty and required between race weekend tear downs , however it did prevent engine failures . Yes it required mixing in heated race trailers & would quickly separate when not in use . It was & is what it is old technology , with proven results both good & bad !
I love Amsoil & Red Armor results when mixed in a properly tuned saw !
Yeah, but recommended for different engine & applications !
In competition hot saws , race saws ok , any other application its counterproductive !
Yeah , you can run it that rich , no reason to , its has a high viscosity index but is an ester based oil with additives . If your saw is tuned for it , you would not see any negative results. Interceptor & Dominator are also fine oils , even without Jaso certification imo .
I’ll grab some garden 2t while I’m on this oil mission. Do you use a stabiliser?
I think there are better choices for OPE, but castor has its place in certain 2 strokes. I just want to burn it in some cheap OPE I have here for the smell. @Trains and @rogue60 who both use saws a lot run castrol 2t and 2t activ. It’s really cheap and neither have a bad word to say. I’ll grab some garden 2t rather than the active as they don’t sell the active in 200mls. Just to try it out. Always nice to save a little $ where possible in equipment I repair and onsell too. I bet, after all of this I’ll return to stihl hp ultra
… I did it with sealants, started with Dirko, tried everything else and returned to it being my favourite . I’d return to ultra mainly because I use motomix for my own quality equipment (doesn’t get used a lot) and having hp ultra oil on hand I can increase the oil ratio of the motomix. Always interesting to try something different and learn from others though. I have a cheap hedge cutter that just gets 50:1 ultra and 91 unleaded. Been sitting in the tank for 6 months so far and still starts.
