What is the viscosity of 2 stroke oil?

i have an old rototiller that calls for a mixture of 6-8 % 50wt oil to gas . can i use two stroke oil,and if so how much ?What is the viscosity of 2 stroke oil?
viscosity is simply the ''thickness'' of oil at a certain temperature...


and 2 stroke oil will do.What is the viscosity of 2 stroke oil?
That is indeed a museum piece. The reason they mention 50wt oil is because at that time there wasn't what we know as 2-stroke oil around, so they used something like a precautionary 16/18 to 1 oil ratio. Yes, 2-stroke will do fine, in fact probably a better job, so I'd use a thinner ratio, try 25 to 1 and see how it goes. That's about 1/3 pint per gallon.





If it goes well and is smoky, you might try a bit less oil.
Sounds like approximately a 1:15 oil to gas ratio. Regular 2 stroke oil is fine, put about 10 oz of oil in 1 gallon of gas. I've never heard of the mixture refferred to in percentages, so make sure its correct before trying anything so you don't damage it.
Wow! that is an old one. it originally used 50w motor oil mixed with gas.


I don't know if 50w oil is even still sold. ask at your local auto parts store.


modern 2stroke oil would probably be fine,it lubricates better than the older oils. oil technology has moved ahead leaps and bounds since that engine was built.
two strokes get there oil from the oil/gas mix. yes you should use 2 stroke oil just put in a couple of caps full into the fuel tank. should be just fine.
yes 40:1 ,and don't ask any more stupid questions you tight-wad
two stroke oil would be fine.
