Fuel Treatments

[drjnap]

I recently purchased a used 1765-DLX with a Yamaha 75-4stroke. EVERYONE! I speak to suggests 1. Change the fuel/water filter regularly. 2. Make sure you use a fuel additive.

I called YAMAHA and they strongly suggested to use "YAMALUBE" which supposedly "improves power and efficiency in 2 & 4 stokes", by removing deposits.

I will use it and in ADDITION, I'm considering either "STABIL" or "STARTRON enzyme fuel treatment" which I believe do essentially the same thing which includes addressing the ethanol issue.

Any thoughts?

You call Yamaha...and they suggest Yamalube.....hmmmm.....lol. Goto walmart and save yourself 20 bucks. 30 bucks yamalube...10 bucks walmart brand.

Sta-bil has a marine formula instead of the standard product.

See http://www.goldeagle.com/STA-BIL/stabil_marine.htm

And Star Tron, according to their product info seems to do more for you with respect to E-10.

See http://mystarbrite.com/startron/

I use it (Star Tron) as well as a few other members that hopefully will chime in. It can usually be picked up at any Walmart in the boating area of the sporting goods section

i use sta-bil ethanol treatment.
search around on the internet some and you can find reports that show that yamalube is a better product than many other oils out there.

I've heard alot of guys use yamaha's "RING FREE" as a great fuel addidtive for removing those carbon deposits. Plan to use some this season.

I use th same Valvoline oil in my 2008 Honda BF115 just like all my cars for the last 30 years !!! :secret:

I have used Stabil red for 10 years in pops 1999 sea horse as well as my old Evinrude... I will be switching to the blue stabil marine as soon as my current supply runs out. It has much more additives in it and you use less per gallon !

I started using Startron with my new Suzy after reading so many posts regarding the problems created by ethanol (particularly when the fuel sits). I don't know if it does all it says, but it is only a few bucks for a bottle, and the bottle will treat quite a few gallons of gas. I have a fuel-water separator, so this is just a little more "insurance" against getting water. I know there are a few guys on this site who also use this product.

I also have always used Marvel Mystery oil in my gas at the rate recommended on the label (about 4 oz per 10 gals). It is a "top cylinder" lubricant and I believe it does add life to an engine by keeping a lot of areas that do not receive oil slightly lubricated. I used it in my old Suzuki outboard and have used it in all my power equipment at home (lawn tractors, etc.). It, too, is only a few bucks for a quart.

I just got a friendly suggestion from Yamaha and a well trusted friend who is Yamaha certified and has been in the boating business for 30 years. I have twin F-115's on our offsihre boat and have never used ring free. We have 260 hrs on the engines and the starboard engine (made Oil) the last trip out. After a full data down load and other test, it was determined that the engine hasn't broken in yet. 260 hrs and just over 160 hrs were at or below 2500 RPM's. Only 10 hrs were at 4000 or better. I was clearly told to run ring free to prevent and clean up carbon deposits to prevent the gas and oil mixture. I have seen an engine that ring free was used in, 2 stroke, and after 1100 hrs of use, the engine was as clean as if it were new. I now have a shock treatment in the tank and an extra bottle ready to pour in.

Plus Yamalube is what I use. I want to use the best I can and all these have excellent write-ups and reputations. Sure it costs more, but I am retired and don't spend a lot of money on other things. I just like reliability since I am disabled and don't need problems.

I've been running SeaFoam for a "fuel treatment" the last few years. One pint for 50-gallons has been keeping my Yamaha running good. Been doubling the amount for long term storage.

Recently I've heard allot about a product called Pri-G, supposedly it is ethanol friendly and treats more gallons of fuel for the expense- I plan on giving it a try soon.

For those of us with Evinrude power...here is what they recommend (I also suggest the use of XD-100 oil):

Sea Foam all the way. Especially for 2 strokes with some age. It is a fuel stabilizer plus a carbon deposit remover. I have never heard of anyone having fuel related problems of any kind when using Sea Foam.

I have purchased quite a few autos with high miles and I'll tell you that I used Marvel Mystery Oil in all of them. Everyone of my mowers,snowblowers and anything else that uses gas. Works for me. I had a Lincoln once and joined a website. All those Lincoln owners swore by it.

[Fayetteguy]

Maybe im not up with it but i have always run the Johnson Evinrude 2stroke oil, and a boat that i rode in for 20yrs ran that stuff so i am biased. I have also added some seafoam every now and then and it has really helped my oldy but goody mariner/mercury/yamaha......sheesh i hope companies never do that again.

nice DO DO on your avatar Fayetteguy

1765 DLX - Yamaha 75 4 stroke.
Thanks for the responses. Since it was the first time out and I did not know how old the fuel was, I drained the tank and added recommended amounts of Startron AND Yamalube, as they serve different puposes. I also changed the fuel/water separator.
(took 2 minutes). I also poured the fuel from the separator into a glass jar. There was NO water in the fuel.
The different purposes: Startron (ethanol issues) AND Yamalube (keep it running clean and free of deposits).
In essence, it purrrred. I was very pleased and zipped in around Charlotte Harbor. I will continue to use both whenever I add fuel.

From what I am able to discern, Stabil (marine) serves essetially the same purpose as Startron. Startron for me is more versatile because I can use it in a motor vehicle that sits (during the summer) or in the lawnmower fuel when that also sits for a while.

Thanks again.

I've used Sta-bil for a few years around the home - mower, edger, weed-eater, chain saw, etc. I had about a half bottle of unused sta-bil sitting around about a year and it started to flake on me, causing me to toss it out and from then I've been a little leery about using it for long term fuel storage. I recently got to thinking about fuel stabilizers and researched for a good while, to find one that I could settle on for all my vehicle, lawn, and marine use. I settled on StarTron for the reasons I went into on an earlier thread, where there was a pretty good discussion on stabilizers and fuel/water separators: http://carolinaskiffowner.com/showthread.php?t=4148&highlight=star-tron

FWIW, I don't recall coming across anyone that uses any brand of stabilizer that has actually said they had a problem with fuel after using their product choice.
