Yamaha Outboard Ring Free Plus Fuel Additive Quart (32 ounce) ACC-RNGFR-PL-32

I received a 32 oz bottle of Ring Free additive from PWC via UPS and the top was taped up and it had leaked in the box. I immediately emailed PWC assuming someone had knowingly shipped a bottle that was known to be damaged. I got a response apologizing for the leak and apparently PWC tapes all bottles to ensure safe delivery, and they did not know it was leaking. I subsequently got another bottle in the mail as an apology. They certainly did not have to do this, and i admire this prompt, customer friendly service. Nice job PWC.....earning customer loyalty one bottle at a time !!`

I always use the best products I can buy for my bass boats. I run a very fast boat that needs only the best products that do the job right and right on the first time. Due to poor gasoline, my engine had some carbon build-up on the pistons. After using Yamaha Ring Free, the carbon on top of my pistons was gone and they looked new again. I now use it with every fill up to keep the carbon from coming back. There is nothing better you can buy!
