no its not. it still has ethanol, and now your engine is not firing where it should because the octane is too high.
What do you mean “not firing where it should”? Yeah, it still has ethanol, but the engines rotate at the same RPMs and burn a little hotter and cleaner. I can’t testify that it’s actually “burning” more of the water content, but, like I said, it’s worked for me for over eight years and it was a racing mechanic who recommended it, so I’m sticking with it. My tractor-drive snow blower is 20 years old and runs better now than it ever has - and it never fails to start.
