yamaha ring free mixture ratio

[mrpike1973]

the bottle says 1 oz. to 10 gallons, however, i have a 3-gallon tank. how much do I need? I bought a little cup that has millaliters. how much do I need or use?

I have used this for years.

I always use a bit more than suggested and have never had any issues.

I had a sparkplug almost carboned up so bad it would not come out.

have run ring free ever since and no carbon on the plugs, great stuff.

Approx 10 milliliters should get the job done. That is enough for 1/3 of an ounce, good for approc 3.3 gallons

1 oz equals 30 mls. 1 teaspoon equals 5 mls. Roughly 2 teaspoons / 3.33 gallons. 2 teaspoons / fill would be good for maintenance. I am running twice that ratio now to try to clean up some deposits. Yamaha no longer recommends "shock" treatments-or so i've read. I have heard that those shock treatments liberalized a lot of carbon and had the potential to foul plugs.

Just had 115 mine done. Dealer recommended according to latest tech bulletin. Watched part of procedure and you would be amazed at the junk that came out. Now I am using the Yamahan ring free. Shock treatment helps stop the problem of 4 strokes making oil

I wouldn't worry to much about a few dollar plugs fouling out as the carbon "chunks" scaring up the cylinder walls when they come loose doing the "Shock" treatment. That maybe why Yamaha no longer recommends it?

My guess to why they don't recommend it, is a properly jetted engine does not need it.

A trick to find ratios for mixing, is to divide 128 (ounces in a gallon) by whatever ratio you want. Example: You want to run 50:1. 128/50=2.56. You need 2.56 ounces per gallon for a mix of 50:1. 1 ounce per 10 gallons is 1280:1 just so you know. For a gallon you need 1/10 of an ounce. Its just about 3 ml.

You're probably right Leech....i just remember the yammie mechanic mentioning the plugs. Although its an easy procedure to change the plugs there are probably boat owners who couldnt even find them under the hood, much less change them. Anyone can pour additive into their gas tank. I wonder if the recommendation changed to protect dummies from making things (function) worse?

If you use your boat enough during the summer you should not need to use Stabil. I'm burning a tank about ever other week so no way that getting bad!
