Any reason not to use 2 cycle motor oil in the gas for a 4 cycle?

[raaamad]

Upper cylinder, fuel and exhaust systems lubrication/corrosion protection.

Seems to me, a small quantity of 2 cycle motor oil, an ounce or two, in a full (5 Gal) tank of gas would be beneficial for every system part, from the fuel tank to the end of the exhaust.

I understand that ethanol has been shown to be detrimental to older engines (pre-ethanol days) and believe a little designed-for-combustion chamber-oil can't hurt, and only benefit any engine, especially one with its supporting appurtenances not designed for ethanol.

However, I do have doubts about catalytic converters.

I've been doing this mostly on and occasionally off for 3+ years, and 25k miles on my beloved Valkyrie, and only been very pleased so far.
Every once in a while, I sense the smell of an outboard motor, and it reminds me of fishing on the river.....!

Just thought I'd put a stick in the beehive and get some perspective.
Please let me know what you all think.
Thanks

On the advice of others in the motorcycle community, I have tried what they consider the best: Pennzoil Marine Premium Plus TC-W3. I put it in my '70 CB450 and in the Valkyrie. I didn't notice any real improvement in either, after two tanks treated at 1oz per gallon, just some blue smoke and oil smell. I'll probably use up the rest of the bottle in my 450, but doubt I'll buy another.

Is it possible that the extra oil can turn into carbon deposits in the combustion chamber?

I don't believe using oil in the gas will create any noticeable improvement in performance.
Longevity, I believe so...

Excellent question

Because modern 2 cycle oils are designed to run through the combustion chamber, I believe any additional carbon buildup would be minimal. My 25 K spark plugs are a nice toasty brown, and do not show any carbon buildup.

I use it all of the time. brand doesn't matter. dose it correctly and I see a consistent 1-2mpg increase.  main reason I started to use it is to keep the carbs components lubed and reduce their wear, esp, the needle well.
the original testing the ones who came up with it.

[Valker]

I use it, and the recommended dosage is 1oz of the oil to 5 gallons of fuel. It should clean rather than cause carbon buildup.

I run Klotz Techniplate in my lawn mowers and snowblower, only because the smell makes me happy

Wonder how many use Marvel Mystery Oil in their gas?  I've used it in older vehicles and it worked well, but what are the experiences using in our 1500's?

BTW, here's an interesting link on the topic: https://www.youtube.com/watch?v=J3F3jDa2xhg

the old tech additives, such as MMO and sea foam have low temp solvents which solidify on the back of the hot valves and carbon up the piston tops during actual use. This is why top tier additives came about and was started by BMW I tend to remember.

VERY interesting!  Thanks for the link.  I guess the best gas would be Top Tier AND non-ethanol in one.

[WintrSol]

I always use top tier gas, when I can; I've never seen non-ethanol at a top tier station, but then, I have to go almost 50 miles to the nearest station with non-ethanol gasoline.

[CoachDoc]

I've been doing it in my '74 CB550 and my '97 Valk for years. I think it considerably reduced the notorious propensity for rust in the old 550's exhaust. The rest (top end lubrication and preservation of carb components) I presume to be true but cannot verify.

[98valk]

"I get a lot of criticism for calling gasoline "dry" by internet experts...clueless keyboard warriors.....much of the benefits derived from this exercise is directly due the cleaning/lubrication properties (of the TCW3) and its effects on the top end and ring pack.
Makes for a more efficient burn with higher compression. Yes we have documented higher compression already."

After 98Valk's first post about this, went out and got a 1gal bottle of 2 stroke oil, 50 or so 1oz plastic capped bottles and three liquid proof lockable fishing fly holders.  Each one holds 4-5 bottles.

Been running the 2 stroke oil all season in all of my girls.

I have no interest in tracking fuel mileage, so can't report to that.  (I never considered MPG when purchasing a Valk.)

The info and testing reports 98Valk provided was enough for me.

I always hunt out top-tier national brand gas, never use local convenience store brands unless there's no option.

Adding a 1oz bottle to the tank before filling up is habit now.

is it TC-W3 you are using? It is ashless per that spec, so zero deposits will be left. common 2-stroke oil will leave deposits.

Crap, I'll have to check, but I believe I did the research and got what was suggested.

Yeah, affirmative on the TC-W3.

[Gondul]

Would pouring the TC-W3 and Marine Stabil in the tank at the same time be problematic?

I do it that way every tank, a few times in summer without the stabil, didn't notice any difference with or without.

[98valk]

here is the specification for TC-W3

[Gondul]

Thanks for the info...

[CoreyP]

2 strokes are dirt as Hell this all doesn't sound like a good idea to me. Only benefit I could see in doing this is upping the compression on a wore out motor. If your rings are good you won't up the compression.

I've had 2 stroke bikes and can tell you the oil in the fuel will gunk things up over time.


Good luck only time will tell.  Just of interest to you guys who are doing this, how many miles a year do you put on your bike? Winter storage?

[Valker]

The recommended TC3W is NOT the same as two stroke oil used to be.

[Gondul]

Well.. I've run a couple of tanks with both the Marine Stabil and the Walmart T3CW and after the first tank I could tell that start up in the morning was quick with little/no choke needed... and it sounds smoother at idle.

I race two stroke motorcycles and this is crazy don’t put any oil in your gas for a four stroke , if you ride your bike on a regular basis and keep your maintenance updated that’s all you need , this is nuts just treat your gas if it sits for a long time with ethanol treatment that’s all, or just ride it all these little tricks and additives don’t work just ride and keep your oil changed regularly.

[Pappy!]

Well boys and girls.........
Let me shed some light on this discussion from a different perspective.
After over 45 years in the marine industry what I can tell you is that carbureted (2-stroke) engines that run on pre-mix enjoy carburetors that remain cleaner than their 2-stroke counterparts that have straight gasoline going to the carburetors with a separate oil injection system.
Two main reasons for this are that the current TCW3 oils have plenty of detergents and solvents in them that will help keep the carbs clean and enough of a film of lubricant that is left behind to keep oxidation at bay when the fuel in the carbs dries up.
Obviously we are not talking about adding enough oil to make the same gas/oil ratio I am talking about but the TCW3 oils absolutely do add cleaning and preservation capabilities where carburetors are concerned.

[98valk]

from the link I provided. ratio to use.

"Use 1oz of the two stroke oil per 5 gallons of gas ( 1oz-5gallons/ 2ozs - 10 gallons etc. and that is the perfect ratio. Too much and it will make your engine run worse....too little and it wont do anything.....use the proper amount.....get a little bottle and keep it in your car.....We have seen a maximum of 5% better MPG down to a minimum of 2% better MPG. All of our test mules reported much smoother idles and cruising. No smoking or ill effects. No residue on plugs our pistons....actually the opposite....we saw "cleaning".....I am now comfortable recommending this for all. I also now run this mixture in my GTO/Mercedes/Silverado and G6 with all having smoother running motors and all gaining MPG. Give it a try and let me know your experience. Follow the mixture ratio to the letter. 1 oz per 5 gallons of gas."
