Interdynamics 374CS Certified A/C Pro Oil and Fuel Systems UV Dye

Does not identify leak

Works great pinpointed oil leak! Have had a slow oil leak on our 2002 Grand Am for the past 4 years. Nothing serious just an annoying constant oil leak In our driveway. Was leaking about 1 quart between each oil change. At first was convinced it was the pan so changed the oil pan gasket. This did not solve the leak nor did a stop leak product. So purchased this DYE put it in and went for about a 50KM drive. Brought it home, jacked it up and had a look in the dark using a black-light flashlight. Lots of oil around the pan is why I originally thought that was the leak source. Using the black light, the DYE outlined that the leak was coming from a much higher spot and flowng down on to the pan giving the illusion that the oil pan was at fault when in fact it was not. Got my answer and found the leak source

Used it for thr first time yesterday and discovered the source of my oil leak quickly . You will need a black light but they are cheap. Recommended .

Worked perfectly. Using UV flashlight saw my leak after running engine for less than 5 minutes. Highly recommend.

It really helped to detect the engine leak

With this oil I was able to trace the mystery leak in my transmission. Worked as advertised. Worth the money. I used an UV flashlight I purchased separately.
