special break in oil?

[phatboy]

hey

when i bought my scoot a month ago i did some work to get it running, scoot had 300 miles .

when i changed oil it still had factory oil in it, I think. it was really thin, i mean thin like kerosene. manual says use 15W40 motor oil it was definitely not that (I used 10W40, i am guessing that's close enough)

is there a special thin break in oil or did a lot of gas get by the rings or something.

I don't trust any factory oil... I changed my oil the minute I got my new scoot... 10w/40 is ok..

Although gas can go inside the crank case oil but not that much... all piston rings are not seated perfectly 100%... as long as your scoot runs fine,, that's ok....  Lots of gas can only come in when you have problems with your ignition system, when you have a flooded engine or when rings are really loose... 

Small engines break down oil very fast compared to big engines.. especially poor quality oils... the reason is that there is only about one liter or less of oil in there that circulates rapidly with a high temperature.   This is one reason why the factory recommends 15w/40 oils...  15w/40 is usually Diesel engine oil and this oil is formulated for trucks and heavy equipment... go figure...

10/40 is ok. It does depent on the weater a little which you live if it stays hot a dry I would go whit the 15/40 colder weather under under 50 or so I would go with the thiner oils.

  Those Lifan motors come with some weird thin oil that smells like kero a bit.
Most people swap it out before starting it. They call it pickling juice, not sure
what it is.

   My Yager came with some red oil that was a bit thin. Motor builders
will tell you to use 30W straight weight oil to break in the top end better so
maybe that's what it was? I swapped mine at 150 miles but used straight 30W
and I will probably stay with 30W until at least 1000 miles.

x2 it just packing oil something cheap to put in so the motor has oil in it. most scoot shops around here will give you free oil to put in your scoot for brake in.

Thanks guys

since the factory fill motor oil was crap, now i wonder how bad the factory fill of gear oil is. anyone change it and find thick oil or something really thin?

I see you just need 0.1 L of gear oil, it calls for 90W and i've never seen straight 90w. I have about half a bottle of some royal purple synthetic 75W140 left over from a fluid change in my car, would that be OK?

A 75W/140 is great for towing like for Jeeps, Pick-ups, etc.... for a scooter, it would be just fine...

Some might say that it will affect fuel economy because it's thicker... that I can't say....

The problem is not really the volume of oil, but the lack of a proper PCV system and that the mixture with a carburator is almost always rich, so the gases inside the crankcase have a very high concentration of fuel and water vapour compared to an engine with PCV where fuel mixture is sucked back into the intake and fresh air is let into the crankcase.

The fuel and vapour is absorbed by the oil and as a result, the oil should be changed much more frequently.
