It works extremely well. My equipment idles better on Lubegard than Mobil 1 racing, and I get zero exhaust spooge with Lubegard as opposed to M1R at the same ratio. RPM's and throttle response is at least as good with Lubegard vs M1 racing 2t. Go buy a bottle and try it for yourself. I'm considering sending one or more people here a quart for free if they agree to do extensive testing and report their results, just to prove a JASO FC/FD, premix only oil is irrelevant with respect to this product and could quite possibly perform worse than it. They don't care about getting it certified because as far as they are concerned, they manufactured a product in what they consider a niche market anyways, because they, like Mobil 1 back in 2007, know that 2 stroke is a dying market because of environmental bs. EPA would really like to
ban 2 strokes nationwide if they could get away with it.
Lubegard has nowhere near the hype like Amsoil and many other lubricant manufacturers, they're not making outrageous claims like Amsoil like saying you can use a 100:1 or 80:1 ratio. In fact right on my bottles of LG it says the highest ratio it should be mixed at is 40:1. You'll find a lot of posts on numerous sites of people reporting engine seizures from using Amsoil Saber Pro.
