Power Steering Oil, what type?
When changing the power steering oil in a W123, what is the correct type to use? I believe the owner's manual says automatic transmission fluid, but ATF has changed since the early '80's. Should I use Dexron, Type A, Type F, or something else? Dexron looks too thin to me.

Regular old PepBoysAutoZoneMcParts power steering fluid will work fine in your 123.

This was discussed quite a bit. You probably have dextron transmission fluid in the car now. This is approved by Mercedes and 90% of the people use it. However the discussion was posted as to the changes in tranny fluid over the last 20 years and it might be better to use power steering fluid. My concern would be changing the fluid might produce leaking seals in these 20 year old cars. Dave

KCM,
There have been a couple of reports here that after the power steering fluid was replaced with auto trans fluid (ATF) in the power steering system, the pump seals started to leak. Therefore I would not recommend putting ATF in the powering steering system. I wouldn't recommend putting ATF in the engine either. ATF is made for auto transmissions and that is what it is used for.

The owners manual for my '82 300D specifically calls for ATF in the power steering system. That's all I have ever used. Never had a problem.

not sure for mb's but
in the fwiw dept., had an A2 VW that could also use ATF in the power steering "if necessary" according to VW. the thing leaked like a sieve so ATF was cheaper to keep putting in....
