I have a SL500, R230, 2003 mod. I`m trying to find a replacement oil for the MB hydraulic fluid in the ABC system. I know that some are using Pentosin CHF-11S for this service. However, as far as I can see based on MBZ approval 345.0, the Pentosin CHF-11S is only MBZ approved as hydraulic oil for the power steering in relation to the R230. Will appreciate any comment regarding use of the Pentosin CHF-11S versus the MBZ`s supplied ABC hydraulic fluid.

 

use the pentosin for the abc. use 20 to 25k miles.

 

Thanks for the reply. I have left a quart of the MB oil. Do you know if it will be ok to mix this with the Pentosin?

 

is it blueish in color? it may be the same but usually more expensive. when in doubt, don't

 

The color is green, same as for the Petosin. I see that MB have different part no. for the power steering oil (Petosin CHf 11S) and the ABC oil, i.e. A0019892403 and A001989240309 respectively. I have not been able to establish the specification for the latter so the possible difference is unknown. Your "when in doubt, don`t" seems like a reasonable solution. Thanks.
