Which V8 engine oil?

Hi guys,

I'm ready to change oil on a 56 Caribbean I look after.

The previous mechanic used 10W-40.

The car gives off black smoke, whether the engine is cold or warm, and I want to rule out the wrong oil weight before I start looking at other causes of smoking.

What type of oil works for you guys? I couldn't find the info anywhere on this site.

Thanks,


Stephen
