Sounds like I might be best served by sticking with the R50 I'm already using. It's readily available here and has higher viscosity than many others.

7.7 cSt is what I typed 8 posts above
80:1?!!!!!!!!! Maybe 50:1, lol. My BIL tied up a blower running an oil at 100:1. I heard of a Lawn Boy doing the same. Oil's not so expensive that I need to run so little, especially when most of mine are ported.
Well I am offering up a Stihl weedeater that my father in law gave me to experiment at 100:1 with the Saber. I will be running it at 100:1 and really don't expect any problems.
I am not convinced that difference in Kinematic Viscosity difference between oils is a big indicator of the oils ability to to protect an engine from scoring or seizing......I just emailed Amsoil to see what they have to say and with it being Friday afternoon I would expect that I won't hear from them until Monday. If Kinematic Viscosity was important.....why would their racing specific oil be thinner than the oil they recommend for yard tools? I think that the kinematic viscositiy of 2.6 oz of oil diluted by 128 oz of gasoline is going to be pretty insignificant. What I believe matters is the shear strength and ability of the oil to remain between the moving parts.
i bought a bottle of dominator at lunch and will mix up a batch tonite to try in the 372. couldn't get the saber in town the dealer for amsoil never heard of it here.
let us know what ya think about it.
As far as the b/c oil it seams to be thinner then the stihl but it is alot stickyer not sure if that is a good thing or not but to me it seems like a good thing.
So are you asking me to sacrifice one of my ported saws to the saw gods by running it on Sabre at 100:1? Think a 260 turning 17,400 would hold up? I can get a new top end for $85 from Bcorradi anyway, LOL.

One thing to remember about Interceptor (and I assume Dominator) is that it's made for injection systems and has no dye. I hate undyed premix. I want to see blue or green fuel go into my 2 stroke OPE.
I've used Interceptor at 40 and 50 to one.
Works fine, but it annoys me not having dye in my mix. The Dominator should be slightly better according to Amsoil, but I bet you'd never detect a difference.
Brad, here's a good test for you. Next time you have a saw torn down, make sure the inside of the case is good and clean. When it's all back together... Mix some Amsoil Saber at 80:1, and run a few tanks through it.
Pull it back down, and see how much oil is covering everything. I was Running Saber at 100:1 in my 038 Super... When I pulled it apart, the crank and jug had blue oil droplets on it. Plenty of oil was in there.
dominator has a red dye in it. It will turn your gas red once mixed and dominator is for either premix or injection
