Example: my car has a full hydraulic suspension system which uses special hydraulic oil the mercedes stealer wants $18 a liter in AZ. I bought Bilstein oil from a parts place in San Diego for $5 a liter- same stuff as dealer.
What exactly is that Bilstein oil that you used in place of the MB hydraulic oil?
How many miles/how long have you used that Bilstein oil?
Do you have the name and phone no. of this place in S. Diego?
