Q. How difficult is it to switch from a petro-based oil in a gearbox to a synthetic oil?
A. It's easy and here's how: Drain 5% of the oil currently used and add 5% of Lubriplate® Synflush. Then run the box for 200-500 hours. While warm, drain the gearbox completely and refill with a synthetic oil. Systems with a high percentage of moisture or visible residue should be drained completely and refilled before using Synflush.
