Need Help!!
IIRC you have to unhook your airbox and remove it to get to the filter. The "cartridge style" filter is on the top passenger side of the engine and a long bolt holds the cover. Remove the bolt and cover, pull out the old filter, drop in a new cartridge, replace the o-ring on the cover and re-secure. The o-ring comes with the filter.
I think the E420 holds quite a bit of oil. IIRC is was around 10-11 quarts. I checked a couple oil change places and the normal charge around here was $55-$65 with non-synthetic oil. You can do it yourself for much less.
