I've used this for 10+ years. Offers great protection and does not gum power valves up.

I switched over to Klotz years ago and I have never fouled a plug since. Stuff smells GREAT, almost no smoke, burns clean. I would never switch back! Cant get enough of this!

R-50 works great but is getting expensive. But aren't they all.
