Bonneville America Forums Forums Technical Forums General Tech ADD to GAS

Any of you add anything to your gas such as Marvel Mystery Oil or Lucas Fuel treatment? I been using Marvel 2oz to a full tank.Upper cylinder lubricant its got to help in the long run.I have used the Lucas in the cars on and off a few times at $8 a bottle.... Marvel oil at wallmart under $3 ...I use it in everything that runs on fuel. What do you guys think ???

I periodically add Amsoil Performance Improver gasoline additive to the gas. A 16oz bottle will run you about $8.00. One bottle of the P.I gas additive is designed to treat 160 gallons of gas. So one bottle is good for more than 32 fillups, which comes out to about $0.25 per fillup.

I haven't had any problems with the bike, but then again I have been using the gas additive since the day I got it. Also, I don't use it everytime I fillup. Maybe every 2nd or 3rd fillup, and everytime I leave the bike idol for any extended period of time (I travel for work a lot).

i use mm oil in all my bikes. good stuff.

My Out-Law has been using the lucas stuff forever. He swears by it. He has several old Triumphs (one's a 1939) that all run like new so I figure it might be good stuff.
I have never used it myself though. Probably should I reckon.

And I believe you are right!

""...but, since I had such a great day yesterday with fellow members Grump and Jerry (no, they aren't the cartoon mice), I'm feelin' a tad frisky today – So, here goes… An example of the exceptions may be fuel preservatives if one was to have extended periods of little or no usage.""


Wow, a true believer! I have to agree PipeDr. I just use the stabilizer material you pour into a lawnmower in November and a chainsaw in March. I guess it works, some years I forget and the 18 year old, $120 Sears lawnmower always fires up. No matter how much I abuse it. By January I usually wish I lived somewhere I didn't need stabil for the Triumph.


Ride Safe.

Right on pipedr! Al. I also do not believe that super duper whammy jammy spark plugs are better for your bike. I also do not believe that higher grade gasoline is better,or makes your motorcycle go any faster. Do not believe that high mileage tires have the same traction level. Do not believe that long lasting brake pads are better. We equate longevity with quality. That is not always the case. I do believe that we sometimes believe good advertizing Al

After seeing a couple of pics of these new Triumph vertical twins with carbon buildup on the valves, I've taken the precaution of adding a bottle of carb/injector cleaner to my gas every 5,000 miles. One bottle is good for 20 gallons of gas, so I just pour a little in before filling up. I don't want my valves looking like this:



I might be just paranoid, and I don't know if it's doing any good. Oh, and I also use a good brand of gas(usually Chevron) and stay away from the Circle K type pumps.

Vegas you might not believe in better quality so next time you need tires for you bike buy a set of Cheng Shin then you will believe paying more is better!And as far as adding to the gas look at the picture above I will still add MMO to the gas like I am been doing for years with no problems to gaskets, fuel lines ect. I do believe that adding touches more then just the top of the rings there is a lot more between that.Advertizing as far as that goes when was the last time you seen a MMO one to me its not snake oil nor is the Lucas stuff MMO has been around since 1923 I do believe it helps keep things cleaner but thats just me

Please tell me how the picture above proves that MMO fixes anything? The picture clearly shows a problem, but it does not in anyway put forth a solution. Never said I did not believe in better/higher quality. Quality,high traction tires, do not get high mileage. You cannot have it both ways.High quality,high friction brake pads,do not last a long time,or your rotors don't,take your pick. Nobody here has photographic/technical proof that adding some oil additive into your gas tank or engine oil is gonna help out with a deposit problem/oil problem.If they do let's see it,I will then become a skeptical believer.We get a claim from the manufacture that their product produces some type of results. Geez,what are they gonna say. Ask a barber if you need a hair cut,ask an insurance sales man if you need insurance. Rarly do you get independant testing from a manufacture to support their claims,ever wonder why? A lot of the users of a product just go on repeating what the manufacture told them.How else could they contiune to buy and use that product.That darn sure ain't proof.Or my best buddy Johnny said it sure works for him,so gosh,that must make it good stuff. Or the manufacture puts forth some celebertiy to endorse their product. That darn sure ain't no proof! I remember last season or so ago, seeing John Force promote Fram oil filters.I find John Force intertaining,but just because he promotes Fram oil filters,does nots meens beans about the quality or performance of the product. Ya gatta learn to be a little more skeptial about stuff you hear/read,otherwise every rat out there will have his hand in your pocket. But that choice is yours,Sir!

PipeDr: Don't hold back Man! Tell us what you REALLY think

I didn't believe in gas additives either until 1989, when I bought a VW Golf. I had the car for about 4 months when I had to take it in for some warranty work and the dealer informed me they were going to take a look at the intake and exhaust valves. The reason being was that the Bosch Fuel Injection system and US unleaded regular gas weren't exactly working the best. The Octane was correct, but the US fuels weren't clean enough. The basic problem was that the exhaust valves would get coated with carbon and plug within 5,000 to 10,000 miles.

The dealer suggested I use a gas additive or come back in a year for a valve job. The stuff they sold was over $5.00 a bottle and only treated 10 gallons. So instead I started using the Amsoil Gas Additive. After 125,000 miles I never had a problem with the engine. Well not until my Son crashed the car beyond repair. Then the engine had a major problem.

The biggest problem I have with most gas additives is that they are 95% alcohol and 5% gas additive. The alcohol does all the damage to components. The stuff I use has no alcohol just the gas the additives.

I don't believe how these simple posts have lately begun to degenerate into arguments... If you like MMO, fine. If you don't, that's fine too. Express your opinion, but let's try to keep it civil. geeeez....
Oh, and just for general info, the manual says not to add anything with methanol, i.e. gas, additives, etc. It can damage the seals in the carbs.

Btw, I agree with pipedr. If that makes me a cartoon mouse, then so be it.... but we did have a good ride on Sunday....!

If you think adding something to you gas will fix something then I said enough!Cause there is nothing that will from any can its prevention I dont want to fix anything I want to keep my SPEEDMASTER running as good as it does for many many miles I have a lot of 20 year old gas powered toys MMO keep the fuel part clean and running good for $3 a bottle I will keep using it oh good luck with your Chin Shin tires.

i have 2 old kaws and they're famous for gummed up carbs, 4 of them. before i used mmo, it was ar least 2 tankfulls of gas before my ltd 1000 stopped sputtering every spring. last year i added mmo instead of stabil and had no sputtering.

i don't think they have much influence on carbon build up though. it's hard to get that stuff off w/ the head off.

i was not paid by the marvel comic mystery oil cartoon figure.

I used STP Complete fuel treatment a while back. It is about 7 or 8 dollars compared to the regular STP treatment which is around 3 or 4 dollars. I'm still having problems with my bike sputtering and acting like it is starving for fuel. It seemed to help a little but the problem came back in a short time. I'm tool challenged (that means I ain't got any) and haven't been able to clean my t-filter. I think I tend to agree with the manual. If it says don't use it, I probably won't.

Some of those additives can make a sick engine last a little longer. thats about the extent of it. with a good engine, at best, they won't do much of anything.

I've used MMO in the past on older engines (specifically, BMW Airhead Twins) to free up rings that were varnished in their lands, due to inactivity.

It worked EVERY time!!

O K now. There is one fuel additive that really works.
"Liquid Schwartz"

Hmm, slap me with a soggy squirell if i'm wrong but don't our modern feuls have additives in them already

????? LMAO!

I'll go with what pipedr says with one exception. I do believe in premium fuel, especially Amoco. Here in the States, most gas companies share the same fuel refineries, that is, they get their fuel from the same place.

Chevron may add Techron to the fuel they get, or Techron maybe some fancy name for a cleaning agent already in the fuel from the refinery, I'm not sure.

Amoco does not share fuel with anyone, and Amoco Premium is totally clear, not the color of light beer. I figure it's gotta be burning cleaner, therefore better for the fuel pump, valves, etc.

I drove an MG for 5 years, and over timre, replaced ****** near everything on it, except the fuel pump. It had the original fuel pump on it the day I sold it, again, I always used Amoco Premium. Come to think of it, I've never had a fuel related repair (except worn carbs and a bad hose once) on any vehicle I've ever owned.

It cost a few pennies more a gallon, but in a bike, you'll never miss the extra money, and if you run cleaner, it will more than pay for itself in the end with lower maintenance and repair costs.

A long time ago, MMO had a kit you could mount on your car that fed the oil in a controlled dosage. If I remember correctly, upper cylinder lubrication was the intended goal. Valve guides used to wear rapidly and MMO did slow that down on old tech engines(loose tolerances and antiquated metalurgy). I figure at worst it does no harm, so putting it in a modern engine could be a benifit. Besides, I just like the name "Marvel Mystery Oil."
