So I was in the neighborhood and dropped by the dealer today. While there, I asked if the still had Ringfree. Instead they offered me a small 3.2 oz bottle of Yamalube Engine Med RX. I asked if it was as strong as the original Ringfree and was insured "...this will do the job." The guy sounded a little unsure when I mentioned SVS so I suspected he may not have understood... "Is this the same as Seafoam?" I asked... "Yah, pretty much, just add one bottle to each tankful." ???? "But what about the shock treatment?" I asked.... "Oh, you don't need to do that." ????

So of course I looked it up on line and found this video below from Yamalube USA. It's a little long so to save you the time of watching it, it essentially says that "Engine Med RX is a diluted version of the same formulation as Ringfree". ???? Sounds more like Seafoam/Marvel Mystery Oil than the original stuff.

It would appear that once again the dealer is clueless...

So... the question is, has anyone used it and is it any better than Seafoam or Marvel Mystery Oil? At $2.50 for a single 3.2 oz bottle, it's a lot cheaper than Ringfree but about the same as Seafoam or Marvel when you consider it only treats 5 gallons or one tank.

My gut tells me this is not going to do the trick for shock treatment... What say you all?

========================

You correct,that not going to do well as a shock treatment because it was never designed for that app and states on label can use constantly ,ring free is a much stronger cleaning solvent to use constantly at each fillup because it contaminates the oil & crankcase while doing its job which is why we here in RSC always rec an oil change post ringfree treatment for SVS.

Thats because it's not a replacement for ringfree,was on yami's website the other day and saw they have what looks to be new/updated packaging on their fuel stabilizer/e10 control fuel stabilizer product along with seeing they still had ringfree for sale there too.

Thats yami's version of a fuel stabilizer that controls issues with e10 and cleans carbon just like sta-bils marine grade sta-bil has always done too because that what they are designed to do.

Ring free is a very strong solvent thats designed to clean really bad carbon buildup from the comb chambers-valves-pistons & free stuck rings too along with cleaning carbs & injectors in the process too.

BTW,newest version of sta-bils maring grade sta-bil now has their latest " 360 coverage " technology too that coats all metal parts in fuel system with a special corrosion/ethenol resistant coating .

That coating protects for example a fuel tank thats not full with x-amount of the tanks bare metal exposed to moisture/air/ethenol all at the same time which after not too long of a period creates a very corrosive environment that can really tear up fuel tanks,mech f-pumps and diaphrams in them and same goes for the carb too if not properly protected by the prodcut you posted or Sta-bils Marine Grade Sta-Bil that i have used for many yrs with great results on bikes/classic cars/mowers/sno-blowers ,et .

Happy Happy motoring.

I'm too lazy to read the whole thing but, nothing's as good as ring free!

IMO if you tune the bike correctly there is "NO" reason to use an de-carbonizing additive of any kind. Especially every tank full of gas. I might use it in the last tank of the year along with fuel stabilizer if it is on sale. Then I use whatever is on sale for a couple bucks. I had my engine apart to do the Big Bore and there was absolutely "NO" carbon out of the ordinary anywhere. I'm not saying that it is harmful to use I'm saying tune the bike and there is no need to waste your money. JMO

My words exactly many years ago. Glad I am not the only one that feels that way. Mine was in great shape when I pulled it down too. A good tune no matter what carb and good HIGH quality oil and do a oil and filter change regular and you won't have a problem. (Just don't stip threads)

YUP,good carb tuning is key for clean combustion but there is more that affects additional carbon buildup in a motor.

That would be other issues like for example worn valve seals & guides or worn rings causing oil use, or oil being sucked in from cankcase breather which in stock form is a known issue with the r* to maybe even someone running a dirty partially clogged air filter causing richer mixture all of which cause dirty combustion resulting in more carbon buildup in combustion chambers too.

Just say'n!/LOL!!

Good state of carb tune and 4 ounces of MMO at LEAST once every 500 miles, and you NEVER NEED ring free to begin with.

In reply to this post about that product. The Engine Med RX bottle that I have says its concentrated version of ringfree plus other additives good for engines. You follow directions and add so much (1/2oz?) per 5 gallons gas and I had excellent outcomes using this product. I had SVS so bad that my bike shuttered and vibrated so bad you couldn't sit on it. I treated one full tank, let idle to warm up and rode off and before the first couple miles my bike never ran as smooth as it did. Now I had used sea foam and berrymans and nothing helped. Changed gas each time I used a new product. So I went after the ringfree and ended up using this product.

Curious about the product aside from its details on the back of the bottle I contacted my "contact" with Yamaha and got better details. Yamaha deliberately had this product made to be run with your fuel and not to be concerned with oil changes. I also used the product on a motor that hadn't run in 40 years and freed that sucker up in no time flat.

i work at a dealer and they do still sell ring free but its called ring free-plus its 24$ a bottle and lasts me like 6 months. they also sell that engine med , and an additive called fuel med . thay all are for different " purposes " yamaha says in their sales catalog . so that parts person is not fully educated . however the effectiveness of any of them i cant speak for . and the shock treatment is 2 ounces to a gallon .yamaha made these changes 5 years ago and just make it to different markets at different times the rep told me but who knows.
