Hi All,

I have a 2006 E90 330d and I checked the engine oil today using the dipstick.

Checked on a cold engine and it was on min.

Warmed the engine to optimum temp, left it for 10 mins checked again and its on max.

Is this normal?

I belive its most accurate when at running temperature also any inclines or declines effect it so try a flat surface aswell

I find my 330d oil level on the dipstick to be annoying to read. it's never the same, I just check it every now and again to make sure it has oil and leave it at that.

Yeah I find the oil level changes when cold and hot too, never really know which is right :/

Oil should be checked at operating temp. Once you know it's at the right level, check it again cold and then you have the choice of which level to use. I would not recommend adding oil to the full mark when cold.

For my 320d e90, half full cold is perfect.

Thanks for the replies. I checked it again today at operating temp and its on the full mark.

I believe the book says check when hot but 5 minutes after engine shutdown.
