Notice my edit. IE additives don't really change thebfact ester oils are not great for corrosion protection. For starters you can't get the treat rate high enough with them before you are over sulfated ash limits.

I think it would be very hard to find someone willing to ship it.
I read that study years ago. Basicly it recognized the benefits of PIB. IE very high film strength and resistance to liquid gasoline wiping it off. It also set limits for concentration. Above which the increased bearing temps noted may appear. Is this surprising given ita a high viscosity fluid? Not in my opinion. High viscosity lubes always do this.
Regardless, 30 years latter all the latest two cycle formulations contain PIB and for good reason.
Yep , i hear you brother . Reverse engineering is never absolutely effective !
Absolutely right , very little capilliary action involved within the higher viscocity oils . More film strength but very little creep to protect those rollers .
Blue oil is good oil
The heat comes from the churning of the roller against the thick fluid.
I agree , high viscocity oils often do not maintain minimal boundry viscosity for the class of bearing fit utilized . Optimium Kinematic viscocity is often not met also , which will certainly involve creation of friction & potential bearing wear & lose of critical tolerances that under load can often attribute to catostrophic failure . I worked with a few bearing / lubrication specialists during my tenure in the Steel Industry . Ultransonic & Infrared Thermal preventative testing would indicate abnormal noise frequencies & higher than normal temps that would identify bearing wear prior to actual bearing failures . So that proper pm scheduling changes could be developed on critical equipment to reduce future unscheduled downtimes . I realize that many of my industrial applications involved low rpm & high load applications rather than the high rpm & low load that are routine within a saw usage , however much of the basic working knowledge of bearing design & maintenance is transferable .

Test or no tests, advertising or no advertising, Amsoil has amazed me as a mechanic of over 25 years. I wouldn't trust my life to anything else in my paramotor. I run nothing but Saber. ZERO carbon buildup, and it keeps the fuel good for far longer than you would think. There's plenty of good synthetic off-road oils out there by a few different brands, but when temperatures get stupid high, you can't beat this stuff. Hardly a company with a bad reputation.
The stuff has also kept my truck alive towing stuff I shouldn't have towed with a half ton pickup.

I agree Smitty . I have used Amsoil Products since 2013 . I agree with Ben also , that they put out a lot of hype though . Although , I can't find better sourcing of product for the $ . I currently have 5 gallons of Red Armor I got for a very good batch price . I use Sabre in all my recreational saws , very good results for over 10 yrs . My Commercial grade have always ran Interceptor & more recently Dominator . I like the Red Armor , I just finished a trial with it in one of my old 650 race sleds , nice product for a vintage factory modified free air triple . 
I have been using Amsoil Saber in my Stihl backpack blower for years and years.
Not at 100:1 Wolfy ?
HELL NO 40:1 seems to be working good.Not at 100:1 Wolfy ?
Sorry lol , just yanking you chain bud
. How's life treating you ?
I know you well enough to realize that. Happy New Year.Sorry lol , just yanking you chain bud
Happy New Year to you & yours brother !
Interesting way you have your Hoe bucket secured?
Much of the carbon buildup in a two cycle motor comes from the gasoline and not the oil. After all a four stroke motors piston will be covered with carbon. If your motor truly has zero carbon than you are pig rich. A properly tuned motor should have a piston that is covered in carbon save a small amount of wash if the transfer ports discharge flat.
Saber isn't even Amsoils highest quality product.

Just had to keep it from swinging side to side for the 8 mile journey home. I'll NEVER haul it with that truck again, nor will I load it that way. I couldn't go over 20 mph because it was so friggin tail heavy.
I was talking about the exhaust port. Of course every engine has carbon on the piston! That's like saying, "Water is WET".
When you have a trail of black spooge pouring out the exhaust, you need a better oil. That spooge will eventually choke off exhaust flow, turning as hard as a brick. Seen it a million times in everything from chainsaws to open-class 500cc motocross bikes.1st pic, you can see the point where the prop passes the exhaust - this was 50:1 on Maxima. I had just switched to Saber, and hadn't cleaned the prop. On Maxima, black spooge oozed from EVERY part of that pipe! Made a friggin mess. 2nd pic is Saber at 66:1. Both with the same high / low mixture screw setting. After the Maxima burnt off, the pipe has remained super clean.
