| General Service Bulletin (GSB): | Engine Oil White Fluorescent Dye Usage |
| GSB Overview: | This document provides information regarding usage of white fluorescent dye for diagnosis of engine oil leaks. |
| NOTE: This information is not intended to replace or supersede any warranty, parts and service policy, Work Shop Manual (WSM) procedures or technical training or wiring diagram information. | |
Overview:
- White Fluorescent Dye now available for engine oil leak diagnosis
- Provides distinct white glow to separate engine oil leak from transmission oil leaks.
- The new white dye is Rotunda Part number 164-TP33200601.
- Requires use of a pure UV Diagnostic inspection lamp like Rotunda 164-TP8695 or 164-R3748 available through the Rotunda catalog.
New Dye Service Procedure:
*IF FACTORY FILL OIL WITH DYE IS PRESENT, CHANGE OIL AND FILTER PRIOR TO USING NEW DYE.*
Use the 12 Volt Rotunda 164-R3748 or 164-TP8695 Pure UV Diagnostic Inspection Lamp with white dye part number 164-TP33200601 to carry out the following procedure for engine oil leak diagnosis.
Refer to Workshop Manual Section 303-00. Under Diagnosis and Testing, locate the “Engine Oil Leaks – Fluorescent Oil Additive Method “ Component test and follow the WSM instructions.
NOTE: This new dye will glow fluorescent white rather than the traditional bright yellow or orange.
- If transmission leak is suspect, use Rotunda Tracerline 164-R3700 or 164-R3754 automatic transmission / power-steering fluid dye that fluoresces yellow and yellow/green respectively to aid in differentiating a leak between an engine and transmission.

Yesibeike Oil-Based UV Leak Detection Dye 150 ml, for Dirty Engine Oil, Precision Nozzle, Works with Engine Oil, ATF, Fuel & Hydraulic Systems, Low Odor, Tamper-Evident Foil Seal
- Works Where Used Oil Makes Leaks Hard To See: Designed for real world oil conditions where dark, used fluid can make leaks easy to miss. When checked with a UV inspection flashlight, leak points show up clearly, even in dirty engine oil
- Precision Nozzle Keeps The Job Clean: Switch to the pointed nozzle cap when you are ready to use it. It gives you better control, helps avoid overuse, and keeps dye from dripping onto surrounding parts, tools, or engine surfaces
- Finds Small And Intermittent Leaks: Designed to help pinpoint micro leaks, slow leaks, and multiple leak points that are often missed during quick visual checks, especially in complex oil systems
- Made For Automotive Oil-Based Systems: Safe for engine oil, fuel systems, transmissions, ATF, power steering, and hydraulic systems. The dye circulates with the fluid to reveal leak sources without blocking or damaging oil lines
- Low Odor: No harsh chemical smell while you work. The 150ml size gives you more coverage per bottle, and a tamper-evident foil seal under the cap helps prevent leaks during shipping and shows the bottle is unopened when it arrives
