We are changing the power steering fluid in our 2012 IC RE with Maxxforce DT. IC says the fleetrite fluid is the only acceptable fluid to use in the Power steering/Fan hydraulic system.
I cannot find any specs for this power steering fluid.
the fleetrite power steering fluid is $8.02 a qt and the system holds 6 gal.
is anyone else running something else?
these buses are still under warranty and I am worried about if there is a future issue and it not being covered because I didn't use the fleetrite P/S fluid.
10w-40 has been a generic replacement for hydraulic fluid for decades, so 10w-30 should be good. A majority of our rear-engine transits use 15w-40 per the OEM. We avoid ATF when we can.
