I just got a 79 Zagato here in the US. I'm sure these questions have been answered somewhere on the site, I'm just having a hard time finding it. This is my first Classic car so I'm still finding my way round. I have dropping oil pressure when warm and oil is low. The sump is a bit wet so I'm not sure if I have a leak or if I'm burning oil. I'm planning an oil change and clean up and then start to work out what I have.
What oil filter? Hayes manual just says Full flow disposable cartridge. What oil to use? Dino or synthetic? What brands and viscocity?
Do you add a zinc additive?
All help appreciated
