Ring Free

I just got a 2005 225hp HPDI do you need to use ring free in the HPDI????

Thanks for the help

It's highly recommended. Some guys will also tell you that Sea-Foam is just as good too. I don't doubt that it is, but your Yamaha manual recommends the Ring-Free by name, and I just decided to go with it. http://xs-s.com/zf/images/smile/emthup.gif http://www.bassboatcentral.com/smileys/popcorn.gif

Oh Yeah...Welcome to the BBC too jhb..... http://www.bassboatcentral.com/boardstuff2/beers.gif

Thanks for the welcome and the info......... http://www.bassboatcentral.com/boardstuff2/beers.gif back at you

Sorry, one more question...do you use it at every gas up?

Yes I do. It's real easy to figure. One ounce of Ring-Free per 10-gallons of gas. My tanks are almost exactly 2-gallons per inch of fuel in each of them. I don't worry about the mixture being perfect, just real close to the recommended amount. I often add a little more Ring-Free than necessary. http://xs-s.com/zf/images/smile/emthup.gif

Thanks again, that just made it real easy for me. http://www.bassboatcentral.com/smileys/smile.gif

I use ring free a little heavy every gallon of fuel since new it should keep carbon from building up. Enrico http://xs-s.com/zf/images/smile/emthup.gif

Sea Foam go by the label. works great for me. I have not any problems with starting or fouling plugs. http://www.bassboatcentral.com/smileys/bows.gif http://www.bassboatcentral.com/smileys/bows.gif http://www.bassboatcentral.com/smileys/USA1.gif http://www.bassboatcentral.com/smileys/USA1.gif http://www.bassboatcentral.com/smileys/USA1.gif http://www.bassboatcentral.com/smileys/popcorn.gif

I switched over to Sea Foam earlier this year, after having used Ring Free from the first day I purchased my boat back in 2002. I'm much more impressed with the Sea Foam than I am with the Ring Free. I've been using 3/4th oz. Sea Foam per gallon of gas.

The important thing is to use one of those products every time you purchase gas!

SeaFoam is cheaper and better IMO.

Just curious as I switched over from Black Recently..... how do you calculate sea foam as cheaper when you have to use up to one ounce a gallon and the ring free is one ounce every 10 gallons ? I just cannot get it to compute http://xs-s.com/zf/images/smile/emthup.gif

Sea Foam is a lot more expensive than Ring Free at the dose I'm using (3/4th oz. Sea Foam per gallon of gas). But my engine idles SO much smoother than it has in years, and I don't have that black carbon buildup inside the prop cavity area like I always had when I used Ring Free, that I don't mind the extra expense at all. http://www.bassboatcentral.com/smileys/smile.gif

Now that makes sense..... I just could not figure out the cost savings associated with sea foam due to the lower initial cost, but more dosage per gallon...... Thanks !

Use them both @ one (1) oz per ten (10) gallons of fuel. The sea foam will clean just as good and cost WAY less. I use the one to one (1:1) ratio just after christmas when I take the boat out for the last time.
