Viscosity of a mixture of diesel & hydraulic oil

What is the approximate viscosity of a mixture of 17 gallons of 10W-30 hydraulic fluid and four gallons of #2 diesel? Consider an operating temperature of 160F.

[Apparently someone added diesel to the wrong reservoir in a skid steer while it was on the job site. It then ran for ~ 15 hours or so. I am just curious as to viscosity of the diluted mixture as some means of potentially forecasting the damage.]
