coolant type/ differential type

5232 3
does coolant type realy matter? as long as its aluminum compatible and low sulfar isnt coolant just collant. i read alot in this forum to buy mercedes only oils. but thats just so thay can charge you for the same product.
and how can you tell if you have a lsd differential or not? and what oil do you recomend for my 300sd synthetic?

Hi ladybee,

I don't know if your car has limited slip or not, but I just posted the codes a day or so ago. Look at the body tag on your car, area 6 for Optional Equipment. Limited slip is code 211 as you will see in the post below.

Cheers, MBL

Depends on the day!

Mb coolant or the Zerex G5 (same stuff..). Don't use ethylene glycol (ie green stuff) and change your coolant every 2's worth it.

I use Redline Haploid gear oil 75-90W synthetic in all my MB's. Works great thus far and they All get a regular work out[:D]
