My car is a 1986 XJS with an AJ6 engine. I'm not sure if it's supposed to work on leaded or unleaded fuel. I've heard every engine from 1985 can work on unleaded fuel, but when it comes to my car... Can anybody please answer this question? Thanks.

if you have catalytic converter don't use leaded gasoline

You can use unleaded fuel even in older engines. Engines with aluminium cylinder head and steel alloy valve seats can use unleaded fuel.
