I just purchased an Allis Fiat 5050. Before starting to use it, I wanted to replace all the fluids, it's been sitting idle for months. I got the operators manual today, and under engine oil it says Multi-viscosity "Allis-Chalmers Power Lube 15-40. I'm using Rotella 15-40, and have been for years, so no problem there. But what is really confusing me, is that under Transmission & Hydraulic Oil, it also says to use "Allis-Chalmers Power Lube 15-40. Have I been around automatic transmissions to long ? Does it seem right to use engine oil in the transmission and hydraulics systems ???
