2 Stroke Oil (Cerma)

[jughead500]

Or maybe its a diesel and bobs a little big for it? just kiddin bob. I like how diesels roll coal when they got a load behind them.guess im the only one that rolls my windows down.or maybe all farm boys do that.

This one's even better. 15,700 rpm. Wonder if they touched that high speed screw?

that's "Obama" oil...

says "multi-racial"

I am confused, I put gas into a tank under my moped seat.
I put 4-stroke oil in small plastic tank on the side of my moped.
Where is the oil going ? its injecting some-where ? Gravity fed
or some-thing. I am confused ? Takes for ever to empty the oil tank.
one quart of oil lasts for-ever.

Ummm.......does it sound like a four-stroke or two-stroke when it's running?

Does it go.........Ring, ding, ding, ding, ding?

I'm thinking you have a two-stroke on your hands.

Does it look like these.do you know the year? 4 stroke oil should go directly into the crank case on the motor.the two strokes should have a seperate tank for combustion oil and one for gear oil.the gear box is always seperate from the cumbustion (chamber) like the 4 strokes.

The fuel and oil automatically mix....its a 2 stroke and thats why the 4-stroke oil smokes so bad would be my guess

Yeap.Its a wonder the 4 stroke additives haven't fouled the plug out.

If you can, take a look at the head on the engine. If it's all fins, it's gotta be a two-stroke.

Ok my turn to try and shed some light onto this little scooter. What kind of oil have you been running? Is their a dip stick on the fill plug? Is the oil res plastic or metal? If it is plastic it will not be a four stroke.
I had a yamaha xt500 four stroke that used 10-40 so bad you would think it was a two stroke. The rings were shot. I didn't have time to tear it down. So just for grins I started adding some yamaha ring free to the gas. And after about four tanks of gas. The oil usage was cut in half.
Definitely something to try.

Now that makes sense . Maybe I really don't know what I got ?

stupid. I got to do my home-work ! I had to be mis-lead when I bought it.

Oil injected with a pump.

Maxima k2 race works great at 32:1 lubes very well when pulling the muffler to check . But close quarters it stinks , very smelly stuff. H1r is also fantastic as well at 32:1 , my first choice . Royal purple is also top notch at 32:1 I will run that and never give it a second guess . I won't thinner than 32:1 . Stihl gray bottle seams to leave a crap ton of black crap on the top of my Pistons and in the muffler and I get a headache for 2 days . I don't really give to much thought to spending 10-20 every couple weeks on oil when I'm spending 150 a week in fuel for my truck and an oil change on my truck cost 125$

Not true ........... some 4 strokes have nothing but fins on the head

OK, so now there is no crankcase oil .........

If you are putting oil into a tank on the side, it is a 2 stroke and you should be adding 2 cycle oil.
Regular engine oil will smoke alot, and you should pull the spark plug out and install a new one.
I would drain the oil from the tank and add some Lucas. Its pretty inexpensive for great 2 cycle oil, and it smells ok too.

The oil is getting mixxed with the gas as it enters the motor.

Or maybe you're to stupid to know when that starting method is the best way. Go back to the firewood pile.

Easy now sweetheart, It'll be ok

Yes thats right…I am going to Mikes Cycle World tomorrow to make
100% sure . I guess I will get all the #'s and info I can find on the
Moped so I'll be pre-pared.
