The one that costs the least.

The one that costs the least.

All I know is that I just did my 50 hr maintenance and the spirax quieted the hst substantially. I can't speak to the mobil, but I assume its specs are similar to shell and it's also a recommended replacement oil. I agree, buy what's cheaper and give it a shot.

Is your HST loud? I might have had a little noise with my CK30 HST, but the DK45 HST makes NO HST noise. You must be enjoying that cab, you're really racking up the hours fast!

Either fluid is recommended by KIOTI Tractor. If it was a HST, we would recommend the Shell Sprirax. We have had excellent results with the Spirax (Donax) in HST Transmissions.

Thanks for the replies. The local wally world carries the Spirax so it looks like that's what I'll be using. Thanks again!

Is Spirax synthetic??

I wouldn't say loud, but it had a whine that's now gone. Seems smoother too.
