East Central Iowa | I agree with the CAT idea. Your not supposed to mix ATF with hydraulic oil anyhow, although that small amount is never going to hurt. If you want to get real technical the dye CAT uses is a UV type dye. Therefore you need a UV light to "really" see it. It's not cheap either, and isn't meant to treat large quantites, but you can. I would just do the machine that your really concernd with, Or buy dyed oil. | |
