| Less trouble: LiquiVac
I do all my own oil/filter changes on both Benzes and haven't been under the
car in years. I use an oil evacuation/suction device called a LiquiVac which
suctions it out the dipstick tube. Similar devices are also available through
Griot's Garage and under other labels (Mityvac I think). Not only is it far
less hassle but it actually gets out more oil than draining through the
oil pan plug due to the lip at the plug in the bottom of the pan. |
