Star Tron Ring Clean Plus Deposit Control - Cleans Injectors, Valves, & Entire Engine to Restore Power & Efficiency - 16 OZ Treats 160 Gallons (095616)

Great price on a great product

Seems to work.

Worked great. Noticed a difference the first day I started using it. Runs smoother and feels like the vehicle has a bit more power.

best quality carbon cleaner for marine motors. 16oz container and 1oz per 10 gallons. best to use on a routine basis to clean your cylinders and fuel system. highly recommended to use ethanol free gas with this too for ultimate engine protection

Was having trouble with my two-stroke outboard and could not get it to quit missing despite some new plugs and cleaning the optical ignition. This did the trick. I think two stroke mix had evaporated in the line and carb and left behind oil gunk. I got a couple of mph and revolutions on the top end and smoother idling on the low rpm. I used this in the first tank of the season to break the sludge and will use the concentrated blue bottle to keep the tank clean during the summer.
