The Stihl one shots that you mention (the red HP oil) is not a weaker oil it is the same mix ratio as the green ultra and super. Trust me on this I worked at a Stihl flagship dealership that shipped more Stihl machinery than any other dealership. http://www.frjonesandson.co.uk/
There's loads that can go wrong with these cut off saws. As mentioned above and especially with the TS's and other cut off/block saws. Lack of filter cleaning and run time maintenance plays a major part in these breakdowns, especially when used dry without plumbed water. Concrete and brick dust get through the pre filter and main filter, into the engine and wears internal parts - bearings, seals, piston rings etc. As the machine reaches optimum running temp air leaks past crackcase seals and other problems develop.
Remember as well with higher tools that the people that use them may not be as mechanically sympathetic with regards to warming the engine before use. And as we know it is at during this stage when most wear occurs. When I've gone to demonstrate machines in the past I've seen arbourists, contractors and the like on site start a M/C's and just rev the granny out of them. They use stale fuel with sawdust and concrete dust in the combi cans. I've even had machines come back to the workshop with chain oil mixed with fuel and 2 stroke in the chain oil tank. They walk in chuck the saw or whatever on the counter and rant on about the fact that it was only serviced last week blar blar. I've worked out that some people that cut trees anen't the brightest bulbs in the box.
Anyway I think this should be in another thread because it's sort of gone off topic a bit. By all means start a new topic and I'll go there.

Some say that he eats habanero chilli peppers dipped in oil of capsaicin for extra bite and that his pyjamas are made from Nomex. All we know is, he's called Ad the Bad
