Hi,

Bought a 1985 L200 a while ago, it has a 2L 4G63 carburated engine.

I'm wondering what oil I should use for it?

The previous owner can't remember what he put in it, the oil looks new but in case it goes below minimum I need to refill something that would fit the engine and hopefully be the same as the previous owner used.

Would mineral 5W-40 be okay? I use synthetic 5W-40 on my 1989 Galant with a 2L 4G63 injection due to the cold weather in Norway and the tiny oil ducts for the valve cover. Any thicker oil will take longer to arrive so it ticks loudly until it gets warm (apparently normal on the newer 4G63s, my other 1991 Galant GTi w/DOHC 4G63 also has it)
