Got a new zx 225 with a 225 sho. Do you guys run ring free only? Does it help with fuel break down or only keeps everything clean. Also best place to get it? Thanks.

I run marine stabil plus ring free.

Nope

I think it helps with carbon build up on the rings. All of my Yamahas I've used ring free 10:1 mix. I know several guys on here say they use other products that is cheaper, but I've always done what the manufacturer recommends. I always buy my ring free at Plano Marine because they treat me like a paying customer.

I�m gonna run ring free cause it�s under warranty till 2022. Just wanting to know if marine stabil was needed also.

If you use a lot of ethanol I would use an additive. Startron or something similar. The 10 micron filter helps but if the boat sets up for awhile the filter won't help.

Ring free to keep carbon from building up

Then a fuel treatment if your area uses ethanol

This, its cheap insurance.

I'd run seafoam not stabil...

When you say � sitting for a while� how long is that? 1 week,1month??

to me its about a month. Maybe a week or two less in the winter, when more condensation could occur. With that said, I believe it is best to let a boat sit with a full tank a fuel.

Got this off an ethanol website.



Gas Expiration - Ethanol Blend Fuels Have a Short Shelf Life

Ethanol alcohol fuel blends have a shelf life of only 90-100 days, under ideal environmental conditions.

When exposed to water, E10 gas will contaminate and should be discarded.

Only 1 tablespoon of water/per gallon will cause fuel to contaminate/separate!

Replace gas in your fuel tank every 2-3 weeks to avoid alcohol and water related engine problems.

Monitor and Test gas for alcohol and water content frequently.

I wish there were more non-ethanol gas stations in Texas. When you go fish in Arkansas you can find it anywhere

Small airports that have a fuel co-op. I hear that AvGas is Ethenol free, small planes taxi up to the pump and swipe their CC, you can usually drive your truck to them and fill up your cans.

Very bad advice. Avgas such as LL100 has lead in it. Your modern 4 stroke will not like it at all, especially the O2 sensor.

This,^^^^^ not to mention earlier this week 100LL was $3.89/gal at KXBP, and they are normally the cheapest on av fuels at any airport we land. The airports in the bigger towns will be $1.60-$4.00 higher than that on average.

I have a SHO on my boat that is going on 5 years old at this point. I have used Stabil 360 and ring free since break in. I buy gas where and when I need it, always 89 octane. No issues this far.

Thanks for clearing that up. I just figured out the no Ethenol thing. Never considered lead.

My motor is 17yrs old. Never put one ounce of any kind of fuel additive in it. Not one problem out of it.

You lucky dawg you. Is it electric ?

Nope, i just don't believe in all the snake oil additives.

Ring free and ethanol free is all I run n my boat

Word of advice, if you run nothing but ethanol free for a few years and switch to regular pump gas with ethanol you will have problems. This goes back to before ethanol was common place and where all the myths started. Non ethanol will leave a varnish in the tank over time. When ethanol is introduced with will wash it off and that's when the problem starts.
Modern outboards are designed to run with ethanol and it wont hurt it at all. Only solid advice is to use marine stabil if your going to let the boat sit for more then a month or two at a time.

Had the exact same thing happen that tmd11111 describes in a Honda Accord. Varnish built up on tank. I thought it would be smart to use a higher grade of octane once in a while to clean fuel system. The higher grade had ethanol in it. The particles came off the tank and would clog the filter. This happen in the late 1980's.

Why would you think a higher octane would clean stuff?

25 and 30 years ago that is exactly how they were advertised right on the face of the gas pump. Magic in your tank. If it sounds to good to be true it is; but, I fell for it anyway. That is how I got smarter, the school of hard knocks.

Has nothing to do with Octane. Its the ethanol that cleans out the varnish left behind from years of running ethanol free fuel. E10 has been common place for close to 20 years now. All modern outboards are designed to run on it and it wont hurt your motor. Like I said earlier if you're not using it often the keep marine stabil in it and you wont have any problems. Some people just won't let old myths die.

RIng free and 92 octane.... is all I used..
