I am not a big fan of 100 to 1 mixes and a lot will want to argue this.But the fact is no oil mixed at a 100 to 1 will provide a solid ring seal at higher RPM's.Tell you what i will attach a webpage link where a guy did some testing with diff oils and mixtures check it out it's good reading

Here is a direct quote from the gentleman who did the testing i see we feel the same way about 100to1 mixes

I would never use Amsoil 100:1 mixed at 100:1. There is no decrease of carbon formation and I noticed an increase of piston scuffing on the test engine. Even though I have over $20,000 of engines in my shop which I did not purchase on my own money, I still think it is "nuts" to shorten the life of an expensive engine from limited lubrication for the benefit of airplane cleanup.
