Oil or no oil on the dipstick?

[Mataji]

When I check the oil level on my Yanmar 2YM the dipstick always comes out totally clean when I first take it out. On reinserting the dipstick and then looking again it shows oil up to the correct level. I have so far run this engine for 40 hours (total engine hours only 300) and checked the oil at least 20 times. I have not had to add any oil since the last service. I should add that the oil checks have all been done with a cold engine.
I have never seen this before on any car or boat engine I’ve had. Can anyone explain?

My 1600 hour Volvo TAMD61A's also do exactly the same. I well remember the bolt of terror that gripped me the first time I checked the dipstick...

Apparently a lot of modern cars also do the same, according to a club member I was chatting to about it recently.

Thanks SteveN, missed that one.

Same here, now just need to find a way of getting unscrewing the dipstick on the saildrive gear box

My motorhome also does this - came as a shock when I first checked the oil but relieved when rechecked ok!

My Volvo Penta does the same.

Never seen it, or at least noticed it anywhere before...but funnily enough the old man’s TAMD61’s do this too. How do you find them ? Been great engines in his princess so far at least. Relentless power in them. Would hate to imagine should they go wrong though !
