Please, Please be sure that what ever oil you use meets at least one of the following specs: MB 228.51, MB 229.31 or MB 229.51
The Mobil 1 ESP mentioned above does meet this requirement. However over $12 a quart is too much to pay for it. Your local NAPA should stock this Mobil 1 ESP 5w40 for around $8-$9 a quart. I believe most PepBoys store also stock this for around $10 a quart too.
I use Liqui Moly Longtime High Ten. It comes in 5 liter containers (our '10 chassis sprinter takes right under 13 liters to fill with filter) made in Germany. My local NAPA stocks it for $36 a container. Which is around $7 a quart or so. I feel its is superior to the MB 1 ESP. Your opinio
n may vary!
Also the OIl filter is a NAPA 7062. Should be around 10 bucks...
As for the oil change process. The oil pan drain bolt is a 12mm head that is located to the left of center below the front bumper. Its actually very easy to get to, with no jacking required. Be carefully not to lose the coppper gasket for the drain bolt, as the lenght of the bolt is a little longer then I expected.
Be sure your drain pan will hold at least 15 quarts of oil otherwise your gonna end up with a big mess....
The Oil filter housing is accessed from under the hood. Its located between the radiator and the engine on the drivers side. The correct size oil filter socket will save you some stress but I was able to get the cap off without one. There is a air inlet elbow tube running above the oil filter housing that once removed will make your job easier. Just grab the elbow and squeeze it on the engine side. There are two tabs that will pop out and you will be able to remove the elbow.
Once you remove the oil filter housing cap be sure to replace the two o-rings that came with your new filter.
Its actually a very easy oil change to do, easier then most cars. Hope this helps...
