If you used oil that thin, you would have lower wheel motor torque when hot. You could change it summer to winter maybe. You can't get all the oil out, so you would be mixing the viscosties.
I agree. Xw20 oil in winter is not an option. Even in winter, if I run my PT for about 30-45 minutes, the hydraulic cooler fan will come on. And we all know that Xw40 and even Xw50 is preferred once the hydraulics warm up.
