Changing oil on e90
Hi,
This is probably a really dumb question but its going to be my first time changing the oil of my car by myself. I've read on several guides that i should let my engine run for at least 2-3 min. before i change the oil. Why is that so? I know its so i can warm the oil a little bit, but why do i need to warm the oil why can i change it while the engines and oil is cold or room temperature? Thanks!!!! |

Not something to stress over but.

Oil flows better when its warm also the contaminants will be stirred up and more likely to drain . Either way the fact that it's getting changed does good things for your cars long term health. You should do this search on google and you will get a lot more answers. |

That's not a dumb question. Not only will you be able to drain more oil out of your car if it's warm (less clings to internal surfaces), it will help remove anything that may have settled in the bottom of the pan. But in truth, it doesn't make a big difference as long as you're willing to wait a lot longer for the oil to completely drain. Cold oil will trickle out for a long time - up to 15 to 20 minutes -- and if you put the plug back in too soon, you can leave up to a half a quart of old oil in the pan.
But if this is your first time changing the oil yourself, I'd do it when the oil is cold or lukewarm so that you don't have to deal with hot, gushing oil if you misjudge things.

I just finished changing it and i put in the oil and checked the oil sensor and its right at the line that says max. How do i know if i put too much oil? it still has the O.K. sign on it but if there is too much oil with there be a warning light or something?

The disadvantage of the valve is it can easily break off when the pan is about to approach the ground

Are you guys sure that valve can be trusted? Anyone using it for a long time now?
I think it's a good idea, but am unsure it can be trusted... Oil leaks from it would be a pain. |

I have one on my 535i. Works great. Open the access panel, lower the hose, and open the valve. The only downside is that it drains slowly. It usually takes at least 20 minutes to drain out all of the oil, but it's definitely worth it. No mess and no chance of stripping the drain plug. At least on the N54 engine, the drain plug is horizontal so there's really little if any chance of hitting and breaking off the valve. You do need a short extension / adapter though.

It's costing you more than $79, there's the opportunity cost of driving there and getting the work done while you wait. TNSTAAFL
