Basically you go to your local bike store, and ask them what to get for a chinese engine....Anything will do, i myself run Shell oil (15 - 40)
They aren't a ferrari engine so even the cheaper oils will do.
 
75% Shell Rimula-X 15w40 diesel oil. AUD61 for 10L.
25% Shell VSX synthetic. About AUD50 for 4L.

That's the mix I run in my KX450F. Which after 65hrs runs perfect in every way.

You could run a lot less VSX in your mini. That's in there just for cold starts, and the mini heads get oil to them pretty quickly.

Then get yourself a magnetic oil drain plug (ebay part 180206143946) change your oil after every 5 to 10 run hrs (depending on how hard you work it), and relax big time. If you do happen to do 50hrs on one batch of rimula-X take note of how good the oil is (viscosity) when you drain it.

The Rimula-X is friggin good oil. Is it wasn't then shell would get their arse sued off more times than we could count in one work day. Most bike specific oils are good but most are also just a ripoff. And no one can successfully sue an oil company for making a crap bike oil. I use Rimula-X at 100% to 75% in every engine I own. Both cars, mower, pressure washer, generator, and 4 dirt bikes. Try some in your china engine and be amazed at your gear shifting action, and try to measure some significant engine wear too.
 
Are you near a honda dealership? Get Honda GN4. It's $10 for a litre so its not too pricey and it lasts ages.
