Its coming up to NCT ( MOT ) time, next wednesday to be exact, so as its also time for the annual oil change and filter, I did the oil / filter change yesterday, and as they say, every time you do something even if it's a repeat, you learn something new, and so it was yesterday too for me.
Ordinarily, when using the suction pump to extract the oil, I would be working on the principle that if the dipstick was at the front of the engine, then I'd face the car downhill, and if it was at the rear, facet the car uphill. But yesterday changed all that for me with the Merc.
I parked on the patio at home, with the car at right angles to the slope, then put the jack under the front passenger side to level it ( checked with a spirit level ) All fine, inserted the extraction tube, connected the draper to the compressor, started it up, and off we go. It drained about 5.5 litres, and began to slow down a bit. So I jiggled the pipe around and tried again.....no luck. More jiggling the pipe ... then I had the bright idea to jack it up a bit higher...worked a treat !!! pumped the full 6.5 ltes out and perhaps 1/2 ltr more.
Moral of the story is, if you want a 100% engine oil drain from your Merc, face the car downhill...and raise it on the front passenger side. Attached is a pic of the oil sump, so you can see where I'm coming from. The moral of the story is, unless the car is placed right, only some of the oil is drained...and if it is then filled the 6.5 ltrs, it will be over filled. The same would apply even if putting the car on axle stands and removing the sump stud....if it was tilted the wrong way, then all the oil will not flow out.
