Anyone use this stuff, or have insight for use in a M8 engine?

Pros/cons?

Only because it comes free in the Redline oil change kits. Not needed in my opinion for a bike that see's regular use.

I have not used the Red Line. Lucas and Amsoil I have, though.

I do use Sea Foam once per year in every vehicle I operate, gas and diesel.

I do try to stick to Top Tier gas on the bike, and we are fortunate to have a lot of Non Ethanol premium available in the NW.

The only time I have found the need to use any fuel additive is when I get a bad tank of gas. When that happens I use Sea Foam with good results.

I only use Seafoam, and only when I put it up for winter storage.
