Thinking of using Royal Purple

 

This all depends on the weight of the oil. Most MB vehicles take a 75w90 standard weight gear oil. You can definitely change the oil on the car yourself. These do take some special tools to do. the fill and drain plugs are either a 17mm allen or a 14mm allen.

 

MBZ 001 989 17 03 10 is the part number for the MBZ diff fluid, factory weight is 85w90

 

thanks... turns out dealer has it in Liter bottles. How many do I need ?

 

You'll need about 1.5 quarts, so buy 2 bottles. I just changed mine last Tuesday and used M1 75W-90. The drain and fill plugs are 14mm hex I believe, which is a pretty large size that you won't find as part of a common hex assortment. I didn't have the proper tool, so I welded a 14mm(i think) nut to a bolt and made my own tool. If the plugs have never been out they will be TIGHT! You'll also want to spend $3.99 and buy one of those filler dealies that has a 2 foot hose and screws onto the bottle.

 

how often do you service yourself per week?

 

Depends upon whether it's the wife's 'that time of the month' or not. If it is, then daily.

 

lol

tomorrow I will be diy'ing (with the help of a mercedes tech) sparkplugs, supercharger belt, oil change, diff fluid change.

Also putting on my carbon fiber eurotek valence and maybe trying some exhaust mods
