I changed the oil in my 1988 300e for the first time this weekend...not a drip or drop anywhere...

I let the car warm up to operating temperature... brought it into the garage.

I opened up and assembled my oil extractor. Took the air cleaner off, and turned the filter about a half turn.

I guess 15 minutes had elapsed. I then put the tube down the dipstick and pumped the extractor. It took about 25 minutes to completely suck out the old oil. I then got some rags and put them around the oil filter. However, I was shocked when it didn't leak any oil. Put oil around the new Bosch filter and screwed it on.

Put the cleaner housing back on.

Put the 6 1/3 quarts in...and I was done..

I used Valvoline High Mileage 10w 30 (for the winter) There was a rebate offer. In the spring I will most likely use 20w 50. Service records indicate that was the oil of choice during hot months. Bought a case of Shell on sale at Pep Boys.
