I used to use Still Ultra 50:1 and I was a little surprised how much carbon buildup that was on top of the piston on my MS290, it wasn't really bad, but it was more than I thought there should be. A few months ago I got a Gal of the Amsoil Sabor, So far I like it, haven't used much of it. It was cheaper than buying a gal of Sthil Ultra. It must be good stuff if people run it with such low ratios, I won't run anything of mine with those ratios, so far I've been running it at 40:1 with 100LL fuel, everything starts great, runs great, and have had no problems. I don't think there's anything wrong with the Sthil Ultra, but for a better price per gal for a premium oil, I think the Sabor is better.
Ya whatcha usinSo whatcha usin’?
What was bouncing around in that cylinder? Chunks of oil?Yep. Ultra is great.
I might use it for drill bit lube

Looks like the pistonWhat was bouncing around in that cylinder? Chunks of oil?
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" thickWhat was bouncing around in that cylinder? Chunks of oil?

dittoI love oil threads! I use saber at 45:1. I like the smell better than ultra AND most importantly it turns the gas BLUE!
