Ok, I will probably sound ignorant/uneducated... But just a couple of things that I have thought/understood along the way...

In researching what oil to use in my 23rd series, one of the factory manuals/info cited 50 weight. ...not taking the multi/winter weight into account, I would have thought that sticking to that 50 weight would be the best move as that heavier weight had the engine's larger tollerances in mind, compared to more modern-day tighter tolerances. Also, the camshaft as it's lobes receive their lubrication from leakdown of the lifters, don't they? I would think that the heavier weight oil wouldn't "flow off" as easily.

I know that O-D stated using a detergent oil, I have always seen that stated as long as that has been used in the engine most of it's life. ...because switching to a detergent oil after years of non-detergent may loosen up and circulate sludge that would otherwise remain in place in the engine.

Like I said, I was going to stick to a 10w or 20w/50 weight detergent in my newly rebuilt 327cu. I won't even get into the zinc discussion.

I'm just asking, not questioning anyone's knowledge.

Thanks,

Mark
