Simply dip the test strip into the DEF fluid in the DEF tank, and any color change on the strip will indicate the presence of oil contamination. Review: Awesome - Awesome, when I recieved my test strips I happened to have a diesel contaminated def tank on the ground. I tested one in the contaminated def and found it turns dark blue, tested another in fresh def, doesn't change colors at all. If I had had them during the diag wouldn't have had to drop the tank for inspection, would have seen that during then doser flow test and tested the sample.
