DRC Oil

[Atikakas]

Hello everybody!
I'm new ower, save'd one. After 1/2 year the car is 75% done, the car is above expectations, but at the first drive I realized that DRC is equal to zero, loud, unstable ect.
Yesterday I solved the Vacuum/charging points. But...next week I have to goo to technical exam'', and I'm realized that I do not have Oil to refill...1-2 week to arrive .
At moment for a drive, what tipe of general hydraulic oil can exchange the original one G 052 731 A2...? Thanks in advance!
