- UV Light Quality: A high-quality UV flashlight is crucial. I look for kits that include a durable, powerful UV light that can easily illuminate the dye.
- Volume of Dye: Depending on my vehicle, I check the volume of dye provided. A larger volume means I can use the kit multiple times, making it more economical.
- Compatibility: I ensure the kit is compatible with various fluids, including oil, transmission fluid, and coolant.

How to Use the Kit Effectively
Using the dye kit is straightforward, but here’s my step-by-step approach:
- Read Instructions: I always start by reading the instructions carefully.
- Add the Dye: I pour the recommended amount of dye into my engine oil.
- Run the Engine: After adding the dye, I run the engine for about 10-15 minutes to circulate the dye.
- Inspect Under UV Light: I turn off the engine and use the UV flashlight to look for leaks. The fluorescent dye will stand out against the dark engine components.
