oil change

You could go put it on a machine, as in pay a shop the 120.00, it'll pump in new while pulling out the old , gauge...or clear tube shows the color and a green light goes on when the fluid is sensed to be all new.

Let me know how the hose from the lines into buckets works, one with new fluid and one to catch the old, oh but make sure to find a nice shade tree to do this under...so you don't cook in the sun.
