Hello to all…..
I am repairing a Bosch multi-drill model n0. gbh 4-32 DFR., due to an oil leak .
I have established which oil seal needs replacing and now need to refill with the correct oil.
In the service manual ,the oil quanity/grade is described as >35 ml / SAE 20 <
The genuine Bosch oil ( 1 ltr) is extremely expensive .
Would i be OK using SAE 20 mineral motor oil .
Or should i use for hydraulic /fork or other use oil. ?
All replies appreciated
