Keep your injectors clean %26 engine purring.

Use this religiously on my Suzuki outboard. Use to use Yamaha ring free on my old boats and figured I'd give this a try and would highly recommend for the price from a quality brand you can't beat it. Engine runs like a dream.

I used this ring cleaner in an ild gas golf cart engine that ran well but smoked a lot, but after using Star Brite the smoke subsiyed very well. not completely at first but after driving it around a few days it was down to practically nothing. i recommend Star Brite yo any engine that has stuck rings.

good stuff for peace of mind

a good start to the fishing season adding this to the gas to clear out anything and help the seals in the outboard. filled up the tank and it easily and now will run the boat wall cleaning out the engine at the same time.
