We have a smaller compartment under the seat than many because I changed the riser out for a shorter one. (See this post.)

We carry 2 quarts of Mobil 1 ESP Formula M 5w-40. We had to use both of them once when a dealer did not put enough oil in the bus during the 10k service.

We also carry 3 chem lights for emergencies. I used to carry flares but I think these are safer.

An extra oil and fuel filter with clamps for the fuel filter and an extra plug for the oil pan plus a serpentine belt make up the rest of the parts.

Tools we carry are wrenches and sockets and tork tools plus a oil filter wrench and a box of fuses and electrical wire and a simple circuit tester. Also a couple of screwdrivers, crescent wrench and pliers. The 3/8″ socket with a 19mm socket is for use on the tire lugs nuts. There is also a small tire plug kit we added for the Alaska adventure.

The first is the oil filter wrench like the one shown here from europarts.com.

Next you need a set of tork screw driver bits, some tork sockets and some small wrenches in mm size. I seem to use a T-25 screw bit most of the time. Whether of not you need a torque wrench is still being debated. Apparently most of the torque requirements on the Sprinter are beyound what a human can achieve. I just happent to have a torque wrench but have yet to use it on the Sprinter.

Last you need a set of automotive molding tools like these which are invaluable in taking of dash, door side panels, logos and badging (like 2500) etc.
