I don’t know if I would run that. There are 2 things that are questionable: the 276* flashpoint and the film strength.
The 276* flashpoint means the oil itself will begin to burn at approx 276* (typically +/- 3%) which is well below typical cylinder temperatures of a chainsaw. That means the oil can lose it lubricity and contribute to carbon build up as it burns.
The film strength is respectable but I would expect better especially for high rpm as seen in chainsaws. Higher rpm requires better film strength and heavier film. Since it is only rated for 10,000 rpm I would imagine the film depth is on the thin side. The viscosity and pour point is quite low, which means the oil is very thin, too thin in my opinion.
This coupled with the suspension issues makes me question its viability for use in your saws.
