B250 oils

bcdave · Apr 25, 2014

I picked up a B250 Diesel. I am wanting to change all the fluids. In the operators manual it calls for mineral oil for transmission and hydraulics. My oil supplier has never had mineral oil. What are others using?
Thanks Dave

Tractor Supply carries it. 90W for transmissions is the GL1 oil I'd use (if I wanted mineral oil). Non-detergent 30W motor oil for the hydraulics. I have to use pure mineral oil in the transmissions of my Oliver and Case crawlers because the wet brakes can't handle EP additives in GL5 oil. I doubt you need GL1 "mineral oil" in a B250 though. Only reason to feat it is if your system has a lot of yellow metal (brass, copper, or bronze) or wet-brakes. My B275s (got three of them) have had 90W GL5 in the transmissions for years and generic hydraulic oil in the hydraulic reservoir. Ford N series tractors also called for pure mineral oil in the transmissions. That's why Tractor Supply puts "Ford" on the label. I would not use 90W in the hydraulics though unless you live in a hot area. 90W mineral oil is actually 40W when rated for engine use. By engine ratings - 20W or 30W is much better for hydraulics. Any 20W or 30W non-detergent motor oil is fine. So is just about any oil sold as "hydraulic oil."
