    I was wondering what oil you guys are running in your hydro pumps and how often do you change your hydro fluid and filters? I change mine yearly and run mobil 1 15w-50. How bout you guys?

    A little off topic, but did you guys get a lot of flooding up there in Muskogee Nosmo?

    I use Rotella T 15w 40 in my truck. It's one of the only brands of oil that still has the zinc additive that help prevent flat tappet cams from wearing out in older engines like in my 85' F250 4x4 w/ 351w V8
