This guide will show you how to change the oil in large-frame Vespa scooters.

Refilling the oil in the large-frame Vespa requires a narrow nozzle that will allow pouring oil horizontally. A condiment bottle works very well. Put the nozzle of the oil bottle into the oil fill hole and pour or squirt oil into the engine until it is filled level with the fill hole. It is important that the bike remains level while filling, if it is tilted one way or the other, you will over or under fill the engine. Oil will drip down the side of the engine. This is fine, just wipe it up when you are done.

    • There is no necessary torque specification for the oil fill plug. However, make sure that it is tight enough that it doesn't rattle out. It also should not be so tight that the threads strip.

What about the oil to flush the engine before filling up ?

It's been recommend by VESPA drivers...

What do you think about that and what *type* of oil a VESPA will take?

10-50? 20-50? Or a standard thickness?

I have a 1986 LML 150 model.

Please reply.

Thank you.
