Engine oil all gone???

[Super8504T]

Hello guys... wondered if you could help me... when my bike went in for a service a few weeks ago they noted that the engine oil was very low, only 300cc approx drained out. They replaced it with Motul 5100 10w40 4T engine oil. But now I'm very worried.. I've just come to check my oil today to find that when I wipe the dipstick clean and put it back in for checking.. when I take it out.. no oil is shown what so ever. I am really quite concerned about this. Considering that it has had fresh new oil about 3 week ago and I have done about 1100km since the service, is this normal? It's not a two-stroke so doesnt burn oil and therefore shouldnt need replacing all that often? It's weird how it has all gone this quick? There is no leaks either as overnight when I come to it in the morning there is no oil on the garage floor so if its not losing oil.. what can it be?

Something is very strange here.
I would change oil MYSELF and measure everything MYSELF.

..cpl of things could be happening...

...since there are no leaks...

..the shop didnt put enough oil in the crankcase, or your piston rings are shot...

..does the scoot smoke any at all?

..how many miles / kilometers on your scoot?

[Super8504T]

When I picked the scoot up.. it was half way in between the upper and lower level. Now no oil is being displayed on the dipstick. I have had to buy some more oil and just top it up myself. I have used Shell Helix 15w-40 engine oil. I had to fill it up.. I wasnt running it like that. However the chances are that that also will be gone in under a months time.

The scoot doesnt kick out smoke at ANY time, whether its cold in the morning or boiling hot in 28 degrees of weather. It has never smoked. I think you may be right about the piston rings... nearly a litre of oil shouldnt go in that amount of time.

Currently there is about 10500km on the clock.

Please look on the oil container to see how was added.  Keep a record of oil usage and miles driven.  The help you receive here will get this resolved.

..dang....if there are NO leaks, then the only place the oil can go is by the rings....and valves...

..have you ever adjuxted your valves to spec??

No

You don't suppose it's leaking out into the CVT case?  If that was the case I'd think there would be some other symptom, but who knows?  There've been other cases of that happening.  It's easy enough to take off the CVT cover and look.

300 cc (0,3 liters) sounds to low.

When you check the oil dipstick you need to place the scooter on centerstand on a horizontal surface. If the scooter tilts to side a little the reading on the dipstick will be wrong. Dont use the sidestand. If you use the sidestand all the oil will go over the the left side of the engine and you will not se any oil on the dipstick.

Do like this : place on centerstand on horizontal surface and remove dipstick, wipe oil of and insert dipstick in hole but dont turn it. Then read the oil level on dipstick.

Do you know if the people at the shop have been adjusting the valves ?

I would recomend using motorcycle oil instead of the car engine oil, there might not be any difference but just to make sure.

And why would the shop only fill it half way up the dipstick. They should have filled it up to the MAX mark and no more.

If there was a leak you would have seen some oil drips on the floor but you say that issent the case.
So if there are no oil leaks the oil must have come out the exhaust.
Maby you dont see any smoke in the exhaust but it might come out to slow to see any smoke.
Or maby it mostly comes by the pistions rings at high RPM when you are looking ahead.

On my brand new Kymco Super 8 these was engine oil comming out here when the engine was running. From the brown ring.

It wassent much but everthing i made a stop a few drops of oil would come out underneath the variatorcover towards the back there is a hole at the bottom.
I must have seen the oil drops by now if that was the case but you can check by removing the variator cover.



Also when you drain the engineoil its best to run the scooter for a while before because then the oil is hot and you get more of the old oil out.

When you have ridden a long trip shut of the engine and wait for it to cool down and then remove the sparkplug and have a look at it.
If the sparkplug is oily then the pistion rings might be damaged.


If the sparkplug looks fine and there are no oilleaks i would say you are doing it wrong when using the dipstick or the oil comsumption is normal... or the engine i just a bit worn and have a little higher oil consumption then normal.

Thanks for that scootergrisen... I replaced the oil a few last week or sometime and keep checking it regularly.. doesnt seem to be going down all that quick although it is dropping very very very slowly (obvoiusly it would do over time but not that quickly I would have thought.. but it seems ok for now.

Cheers.
