Review: Takes the guesswork out of finding the source of leak. - Works phenomenally and takes the guesswork out of finding where the leak is coming from. Already used it to verify powerstering pump leak and oil leak and saved me a ton of time. 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 ## Features - package height : 15.24 cm - package length : 4.064 cm - package width : 6.858 cm - Product type : AUTO OIL - Country of manufacture: United States ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008PKWH6C | | Best Sellers Rank | #6,720 in Automotive ( See Top 100 in Automotive ) #104 in Motor Oils | | Brand | TSI Supercool | | Brand Name | TSI Supercool | | Color | Orange Tint | | Compatible Material | Plastic | | Customer Reviews | 4.6 out of 5 stars 987 Reviews | | Global Trade Identification Number | 00672264001750 | | Included Components | Unit^Instruction Guide | | Item Form | Liquid | | Item Type Name | Automotive Accessories | | Item Weight | 9.6 ounces | | Manufacturer | TSI Supercool | | Manufacturer Part Number | TD8 | | Model Number | TD8 | | Number of Items | 1 | | Number of Packs | 1 | | UPC | 672264001750 | | Unit Count | 1 Count | | Warranty Description | 1 year manufacturer | ## Product Details - **Brand:** TSI Supercool - **Color:** Orange Tint - **Compatible Material:** Plastic - **Item Form:** Liquid - **Item Weight:** 9.6 ounces ## Images ![TD8 Total Dye, 8 oz (Self Measure Bottle) - Image 1](https://m.media-amazon.com/images/I/719k9lxtSYL.jpg) ## Available Options This product comes in different **Size** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Takes the guesswork out of finding the source of leak. *by S***S on July 23, 2026* Works phenomenally and takes the guesswork out of finding where the leak is coming from.
