Oil: Nothing but 30W Pennzoil conventional for decades now but with a bottle of ZDDPPlus since the zinc was reduced.
Gas: All we can get is 10% corn squeezins at 92 octane. I add some lead substitute since my engine is untouched.
Trans: Dexron X (whatever is the number available now)
PS and Brakes, whatever PS and brake fluids I have on the shelf at the time. Nothing exotic.
Coolant: Prestone at 50/50
