Some cars i.e. 2006+ 530i have no dipstick. No way to suck it out!

So the new synthetic oils have no real purpose (other than improving profitability of lubricant sales) or benefit?

They sure do, if my E60 used a non-syn motor oil, I would have it changed every 3K miles.

You are 100% right. The cars like mine and others still do have the dip stick and you can use the oil extractor to remove the oil. I believe all of the 550 have the dip stick as well.

And we derive the service interval for synthetic oils by applying a personal factor to the number of miles the manufacturer thought of?
