you know, this is interesting.

m-b dealers now use a suction device to remove oil.

and use a pressure device to force new oil into the engine.

i don't cotton to these procedures.

the way i have experienced it is that all the old stuff isn't evacuated, and then the refill overfills. and you know what that means. more problems down the road.

let's have a round of applause for the old-fashioned way. run the car so as to get the lube nice and warm. put it on a lift. pull the plug and let it run into a bucket.
resecure the plug. change the filter.

fill the engine with a known quantity of the proper lube using quart containers.

after refilling, run the engine for 5 minutes. hell take the car for a quick run. then let it sit for 5 minutes. check the dipstick.

make sure that it is not overfilled.

if it is, put it back up and drain a bit more.

nothing worse than damage from an overfilled sump. simply because it can be prevented.
