Review: Easy to use - This stuff works great especially for the DIY save hundreds I've used this countless times for powersteering leaks,oil and transmission leaks and break leaks just have a good I've light and bam
Review: Worked great! Recommend - Worked great. Did exactly what I needed it to do. Had a brake fluid leak. Added to brake fluid reservoir. Be careful adding dye. Do not spill or splash on anything. Start the car and pump the brake a few times to get the dye into the system. Utilizing the UV light I purchased with the dye I was easily and quickly able to see the leak was coming from a leaking brake caliper. Obviously do this at nighttime or in a dark garage or similar to make it easier. The dye glows under the UV flash light

## Questions & Answers

**Q: What color is this after mixed with motor oil?**
A: It’s a fluorescent blue when viewed under a UV light

**Q: How good is this dye?  Does it really work?**
A: Yes. makes oil turn an iridescent blue color.

**Q: How long do you run the engine to mix this stuff?**
A: Not sure what system you are running the dye through but generally I would recommend running for several minutes until your vehicle comes up to temp. That would be especially true if you are checking for a coolant leak so the thermostat has time to open. Good luck to you.

**Q: Can you use this on power steering fluid?**
A: No, use one specifically listed for use in power steering fluid systems.
