There really is no excuse for the shop not using a recommended lubricant. (Maintenance is a planned event, and not having the basics says a lot...) If these are not available locally, they are available from both
IAP and
Centerline. Switch out the lubricant, and find a real Alfa mechanic. (Using a general mechanic is how may Alfas go out of spec, little by little, eventually becoming a basket cases, with years of maintenance that cannot be undone or corrected easily...)
Best regards,
