I am purchasing my first excavator which is a 2006 Doosan Daewoo solar 75v 18k lb machine. I will need to change the hydraulic fluid. I believe it specs for AW46 which is a 20wt. TSC has their Premium universal fluid that is a 10w20 which I believe is a higher quality oil than the AW46. It will also flow better on those 10 degree days. Is this a direct substitute or am I going in the wrong direction with this.
