Mercury Marine Quickleen Engine and Fuel System Cleaner, 12 Ounces 92-8M0047931

Q: Is this how they call quickleen lubricant

Hi too the best of my knowledge it is fuel system cleaner nothing more however it may have some lubricating qualities. I do know that it works well if you use it on a regular basis.I use quickleen 1 with every fill up along with stabil for marine use it helps keep the moisture out of the fuel system.

Q: will this cleaner free up compression relies valves?

I use this more on the preventative side and not fixing carbon build up or other material build up. I do understand you can use a higher dose of this additive and run the engine at lower rpms to help eliminate some of the build up. All depends on how dirty your valves have gotten. I have been using this additive for the past three years or almost 1800 hours on my engine. I have never had any issues with build up.

Q: Does it also act as a gass stabilizer for winter storage?

It is a fuel system and injector cleaner. I used Marine Stabilizer in my fuel tank for winter storage.
