Default Yamaha ring free or sta bil?

I have a 2005 f150 with less than three hundred hours are there any benefits of using ring free in each tank? Does sta-bil perform the same function?

I was actually going to ask a similar question. I currently us Ring Free but that is all. Should I be using something else as well? Non-ethanol gas always. How many additives are too many additives?

No. I'm not an expert but stabil primarily stabilizes fuel for storage. I haven't been impressed with anything else it claims to do but a lot of folks claim that it does keep your fuel system clean. If you're using ethanol fuel, that part of stabil is really unnecessary IMO.

Ringfree reduces carbon buildup similar to what stabil does, but it also claims to protect the metals in the fuel system from the corrosive ethanol in some fuels. I don't have any evidence one way or another about that but I use it even though I only burn non-ethanol gas.

I only use ethanol free fuel also, I was just wondering if there was any benefits to using ring free with non ethanol fuel. The stuff is not cheap

My guy who is reputed to be the best Yamaha guy around recommends only RingFree--says everything else is a waste. One exception--if you not going to run for 30 days he recommends Startron Enzyme treatment. And non-E gas of course.

I believe in it (as an added lubricant for the internals) and to me it's a matter of math and just the way that I do things. One ounce per 10 gallons adds about $.15 or so to the cost of a gallon of fuel. That's $15 for every 100 gallons of gas and I only burn 500-600 gallons a year.

I consider the cost to purchase an outboard at about $1500 per year. If ringfree extends the life of my motor by just one year, it will have more than paid for itself. I buy the best that I can and keep it for a long time so this works for me.

IMO, sta bil or star tron for storage. Ring free at every tank.

Ring Free and Startron, every fill up, for me. Startron is cheap.

There are many posts on this topic...and in several of them is the "formula" to brew your own Ring Free equivalent, which is mainly, I think, naptha (?).

Ring Free does not contain a fuel stabilizer. It reduces carbon build up and also cleans the fuel system. Ring Free Plus, which is all you can get anymore, also contains an additive that protects soft metals in the fuel tank and engine fuel system from ethanol fuel related corrosion. Yamaha sells it's own Fuel Stabilizer Plus, which is similar to Stabil but also includes the anti-corrosion additive.

I use both at every fill up. But if I could use Top Tier gas instead of unbranded Rec 90, I wouldn't bother with the Ring Free except on an occasional basis.

I run Ethanol free 87 in my 2007 F150 and have just started using the Lucas stuff....it's about $10 to treat 100 gallons or so (if you just buy the quart bottle).

I use only Valvetect treated gas from our marina and add RF+ at every other fill up. I add some stabilizer as an added precaution when the boat goes into storage. So far no issues.

Two different products for two different applications.
Ring Free is developed to primarily eliminate/cut down on carbon deposits and as others have said treat internal fuel components within the engine. This is a great and proven product for many many years, it was originally designed to keep 2 stroke piston rings free of carbon deposits that could freeze the ring in the ring land eventually resulting in high temperature blow by and piston seizure.
Startron and all of the other stabilizers on the market are designed to stabilize fuel, the best thing they do is keep the octane of the gas stable. if you fill up with 93 in the fall come spring that fuel will no longer be 93 if you did not add stabilizers. I do not know how much octane it will loose buy many say that after only 60 days fuel has started to drop in octane.
Do not get caught up in stabilizers claims to "protect form the effects of todays ethanol fuels"
What are those major "effects" ? eating old rubber hoses, eating old fiberglass gas tanks, absorbing water, phase separation. There is no miracle in a bottle that can fix any of these "effects' from ethanol fuel.
Use ring free to keep down the carbon, use stabilizers if you do not run through your gas every 30-60 days to keep the octane up.

I'm fortunate to have REC90 fuel available in this area but I still like to add stabilizer to my fuel if it's going to be in the tank over a couple of weeks. I like Star-tron Enzyme.

I use ring free and only Valve-Tect gasoline. I will not use seafoam. I once put seafoam into the gas of my Zero turn. Apparently it increased the cylinder pressure and the head lifted (stretched the TTY bolts). Wound up having to replace the engine after swapping out the head, head gasket and TTY bolts. Wasn't cheap either.

After that, I took a whiff of Seafoam and maybe its just me but it sure smells like alcohol. Whatever else is in the stuff is anybody's guess.

I have been using Ring Free along with Stabil Marine. I would use non-ethanol if available near me at a station that had room for fueling when towing boat with motor home. There is one station that has non-E fuel but almost too tight just for towing with truck. Their primary customer is filling cans for lawn equipment, etc.

Should I use ring free in a new motor only 10 hours?
