Oil change

kav · 10-26-2017, 01:22 PM

I did my oil change today using he oil evaluator. I find it odd that only 5L (just a little less) comes out yet I need to put in exactly 5.6L to get it back to the mid mark on the dipstick. Could there be that much oil in the filter and remaining in the engine?

yes and don't forget as your vehicle ages, it starts drinking some of that oil too

I don't drive much. Just about 2000km on that oil change in 7 months, some of them track miles but did not add any top.

Yes thats normal although I always use old fashioned drain plug style change.Believe it or not - the regular 6 in the nonM Z4's hold another litre!

I thought most oil filters hold around 0.5L up to 1L for bigger filters.

At my last oil change, after I used my evacuator and sucked, sucked, sucked as only a good ....evacuator could, I removed the drain plug. Another 1/3 liter drained out of the pan. Would have hoped it was less, but for that amount I'm still going to use the evacuator.

Long time ago I had a gathering where a bunch of guys stopped by so we can use my extractor to do oil changes on like 5 cars at a time. We decided to put one of the cars up on a ramp and gravity drain it after the extractor was done, and we found about 200ml remain in the crank after the extractor did its job.

Our conclusion was, if you warm up the engine before you extract, 90% of the contaminant will be extracted and you'll have mostly fresh oil. The remaining 200ml or so is not enough to worry about, especially after my mechanic confirmed that the BMW dealership he worked at as a master mechanic also uses a vacuum based extractor for most oil changes, as does he.

The filter housing on our car also holds another 400ml or so, especially if the filter is still wet.

That is quite reassuring. Thank you for the replies.

if its an M, the oil cooler holds about a 1L of oil as well... WHen i do my oil changes, i fill up almost 7L to get the oil near the full mark... if you drian the oil cooler, it takes about 8L's to full

That sounds like too much oil. It should be 5.5 L for a normal oil/filter change. 5.5 Liters brings it right to the center mark for me.

Same here. 5.5L brings me back to the middle even using an extractor

yes you're correct Sir.. I went back last night to check how much is left in my 5L oil can. Turns out i used about 6L-6.2L to get mine to the full line. I'm using gravity drain method (I leave it to drain for about 45minutes) without any oil extractor's.
