Does my car take regular or full synthetic MB power steering fluid? When did the change over from regular to synthetic happen?

The manual just says 'MB power steering fluid'.

The dealer should be able to answer. Convenient, since you have to go there to get the oil.. It is the MB-number that counts I think. Like 238.4 or 238.5
Not sure if they split them up in synthetic or not.. But I guess mineral works fine, since I belive synthetic PS-fluid not to be availiable in 1999 ! ??

Anyone know for sure? I don't have to go the dealer to buy the fluid. I can get it online at a fraction of the dealer price.

Ok,.. I didn't think the dealer price was to bad.. 260 NOK for 1 liter, or 160 NOK for the normal gas-station hydraulic oil.. (260NOK= 36USD)

The synthetic fluid is the one to use. I bought a liter from my local MB dealer about 2 months ago for 8.50 including sales tax.

I don't think any of our W140's take the synthetic.

I used the REGULAR MB OEM Fluid ($7 bucks at the Dealer).

For some reason I thought it was a synthetic fluid. The label says "Power Steering Oil" and the part number is Q1460001.

Well, I just got off the phone with my Lead MB Tech friend, and he confirms:

The "REGULAR" MB Power Steering Fluid is "Standard Oil",and NOT SYNTHETIC!!..., and is used on ALL MB MODELS FOR POWER STEERING....

The "Synthetic"/Pentosin is for Rear Leveling system.... ONLY!!

Hope this clears things up.

I called the dealer and asked them. They said regular power steering fluid.

Thanks!
