Tracerline Dye-Lite All-In-One full-spectrum fluorescent dye easily pinpoints leaks in all oil and oil-based fluid systems, including engine oil (includes synthetics), fuel, automatic transmission fluid, power steering and hydraulic fluid (petroleum-based), the maker said.

All-In-One dye ensures optimum leak detection because it actually contains two distinct fluorescent dyes: one that fluoresces best under ultraviolet light and the other under blue light. Whatever type of inspection lamp is used, All-In-One dye is sure to produce a brilliant glow, according to the company.

All-In-One dye is highly concentrated, requiring only half the dosage of most competitive dyes. To use it, just add the dye and allow it to circulate through the vehicle’s fluid system. The dye escapes with the host fluid through even the tiniest leak. When the system is scanned with a high-intensity UV or blue light inspection lamp, the dye fluoresces a bright yellow-green, exposing the exact location of every leak, Tracerline said.
