It's about using synthetic ATF in the power steering system. It's raining and I can either go to the shop or to the barn, and don't feel like doing either, so I cooked up this question...

Martin,
Just before Hershey I rebuilt my PS pump, installed a new-to-me rebuilt rack, and put in a new PS reservoir. I also let the system drip dry for about a week and then added synthetic ATF. Damn if I can tell the difference

Why cant we use PS fluid..cuz..ATF burns.

I thought ATF is mostly synthetic nowadays???

Anyways, Dexron VI is flowing through my transmission and power steering. Works perfectly fine in both applications.

I am using synthetic Mobil ATF, it works just fine.

Thanks, gentlemen!

Has synthetic ATF any known advantages? I would hope cars burning up because they leaked ATF is not the "advantage". Whether or not synthetic ATF is less likely [or more likely?] to burn if leaked is an interesting query.

No substitute for revamping your hoses if they have not been done already.

Been using Mobil 1 ATF in my S55 AMG steering and ABC suspension system for over a year now in lieu of Pentosin.......works just dandy....and its not hydrscopic?

The only real difference is it has a more uniform molecule size. So if there is a leak, it will leak much worse.

Other than that it has vastly better anti wear properties due to its increased uniformity.
