is the classic sip race oil FULLY synthetic or semi synthetic?


the automatic scooter sip race states FULLY synthetic?


if the classic is not can i use the automatic fully synthetic in a lambretta and premix it without problems?




The label says fully synthetic.

The auto stuff is thinner for autolube type systems and can still be used as a premix for Lambrettas.

if the auto is thinner will it tend to remain in the petrol without separating as quickly if the scooter is left for a period of time?
