New owner - Oil question

[Felipe]

Hello from Oak Island, NC
I always wanted a Jeep and golf carts are lame so I bought a pretty original 45 MB. Mechanically anyway... it was painted a pretty blue by a previous owner.
I have the War Department Operating Manual but no where that I can find does it say how many quarts of oil it takes. Anyone?
So, my cylinder compression 1-4 is ; 90, 80, 60, 88#. What weight oil should I run and does anyone have experience with a cylinder showing 60#? There is a lot I need to do to get 'Ike' running good... Should pulling the motor be priority #1?
Thanks,
pd

Welcome Felipe! The MB looks great. Here is a link for your oil question.

Checking compression does require an understanding of what you are trying to accomplish with it. Checking compression on a cold engine for instance will always yield much lower numbers than a warm engine. 60 psi is low warm or cold. What does that spark plug look like? Is it oil fouled or carbon fouled? How does it run? Does it smoke or start hard? Here is a link with some info on compression checking an engine.

Thanks Friend.

Like the color, it almost looks like a Navy Jeep color.
