JD Hydraulic oil equivalent at NAPA

Erik B · Sep 19, 2013

I need to switch my late B's loader hydraulic oil to the thin viscosity kind for plowing in the Minnesota winter. I've converted it to a live pump and added a reservoir, so I need several gallons.

A few years back, someone mentioned a NAPA regular and thin equivalent that's a lot cheaper than JD's, but I couldn't find that discussion in search. Does anyone know what NAPA's is called?

The main argument over Hydraulic oil is whether or not ot is friendly to wet brakes and clutches,,that won"t be an issue with your B"s system.

Your late B should already have 10w oil in it for Winter. Should cover the cold OK , unless you were using like 30w for the summer.

Hydraulic oil suppliers typically stock in 4 viscosities, 32, 46, 68 and 100. These numbers reflect the ISO viscosity test in Centistokes with the oil at 40 degrees C. ISO...International Standards Organization.

This is not exactly correct but 32 is a high 10w, 46 a low 20w, 68 a high 20w, and 100 roughly a mid 30w.
