Review on 🔍 Tracer Products TP-3090-0601 Gasoline Engine Oil Dye, 1 Pack by Onsommoshit Mathews

I used this item to find an engine oil leak. I filled 1 bottle and was able to find, fix and control the oil leak within a few days. When I added this dye my oil was new so the dye stood out. Maybe a week or so after I added the color it stopped showing under UV light. So you may need to use more if your oil is dirty. Therefore there are no 5 stars. I used 2 different types of UV bulbs: 10W 365 and 10W 395. Both illuminated the dye the same way. The only difference was that the 365 worked better when working with the car in the garage. The 395 was bright enough to work on the car in my driveway on a sunny day. Make sure you buy a real UV LED and not a regular filtered flashlight. I recommend at least 6W of power and an LED. These multi-LEDs do not work.
