Quite few fellows are running one of the three Amsoil 2-stroke oils. See the for sale thread at the bottom for my special and oil description.

Mix ratio depends on the oil, your conditions,your fuel/air mix.

Saber is the most common and protects the best. 30:1 is even pretty oil rich with Saber. 40:1 is fine for a well broken in engine. The oil is designed to work up to 100:1.

I have been using Dominator at about 30:1.

Synthetic 2 stroke oil only lubricates as a liquid. Once it is "flashed"at 237 deg F it no longer works.

Maxima 927 doesnt'flash until 427 degF and when it does flash, it firms dry polymers that provide even better lubrication as a dry lubricant. Its high flash point means you 'll see unburnt oil in the exhaust. Contrary to what Amsoil dealers will tell you, this is GOOD and not bad. The longer it is a liquid, the better lubrication it can provide. Specs and facts can't be argued.

Oh, I did have a lot of training as a tribologist as a test pilot in the military. For what it is worth,we never changed oil in turbine engines based on a schedule. All oil was sampled regularly and sent to an oil analysis lab. Lab would let us know what action we had to take and what wear we were seeing in the engine.

I'll convert the specsfrom SUSto Cst when I have time for comparison.

Actually you can't tell a whole lot about a 2 stroke oil from a flash point. Because an oil flashes in an open or closed cup, does not mean combustion will be complete in an IC engine. There are different ways to make a very well protecting 2 stroke lubricant as you should well know.

Pablo, I respect your desire to promote your product which you believe in but Amsoil only surpasses a castor blended synthetic in ash content, smoke output, and low pour point.

Once an oil flashes it isn't there anymore to do its job. Its that simple. Synthetic oils have their place and AMSOIL has very good 4 stroke products. Its 2 stroke products do not have the same superiority over other synthetics and products as their 4 stroke products do.

In the rare event that a castor blended 2 stroke oil is overheated and flashes, it actually flashes to a dry residual filmlike varnish that is it by itself a lubricant. No synthetic can claim this. Is a castor blended oil perfect? Nope, it has its own drawbacks but I feel that it is the best option for a bushing engine or a roller bearing engine that is aircooled.

Would I ever consider using Amsoil 2 stroke oil? Sure, in a non chinese POS product that has some quality and engineering thought behind it. Using Amsoil in a chinese 2 stroke engine is like putting a pretty dress on an ugly girl...what's the point?

PS I hope I didn't offend anyone who is dating or married to an ugly girl.
