I never said not to use motorbike oil (sigh thread goes off onto oils again)

Don't worry Scooterpuff, no ones having a go... Errr...but it's an oil thread after all. They (we) all go on about oil though. I've got oil in my veins!!! They said that's what could be wrong with me when I went into hospital last year but they'd need to do more drilling and testing to be sure!

Thanks for the silkolene link. That looks good to me. It seems to be the same spec as the Agip stuff Vespa recommend.
