To add further to this issue...the service bulletin that stated the need to wait before checking, (which I can't find at the moment)also stated that the marks on the dipstick were indicators of too low and max. and that the actual correct level was in the middle of these two marks. This was in reference to modern benzes and the apparent issue of overfilling, due to the level being checked before allowing the engine to rest long enough. I'm not sure if the same applies to our vintage cars and I think this has been thrashed about before, but perhaps anyone who knows the right answer could chime in....
Fill to the max. line or half way between the two?
I think if you fill to the max. line on newer cars , they tend to "use" more oil or at least they drop to the half way mark rather quickly. I also understand that it raises crankcase pressure if you overfill them and this can lead to leaking seals....
