I am looking at an alternative to the OE fluid. Napa makes a premium Hyd fluid that says it exceeds permatran III specs. Some people on other forums say do not use it. I do no understand why? If it exceeds the specs than why not? Am i missing something?
If the spec is on the pail i don't see what the problem is,just like fords 134D spec it's on the pail it's good.
maybe they think the additive levels aren't up to pare?
is this just a standard AW 32,46 hyd oil or is it a UTF?
What did you end up using?
I have to do the service on my Massey and need to buy fluid ASAP.
I was interested in the Amsoil 5w-30 hydraulic fluid too, but the only experience I have with it is in the hydraulic steering systems of off-road vehicles (using full-hydraulic steering) in extreme conditions, and it holds up well to heat.
