👉 The distributor fluid, also known as fuel oil or fuel transfer fluid, is a specialized lubricant and cleaning agent used in internal combustion engines to ensure smooth operation. It circulates through the engine's distributor cap, where it lubricates moving parts such as the distributor cap and ignition coils, reducing friction and wear. Additionally, the fluid helps to clean these components by dissolving and carrying away engine deposits, ensuring optimal performance and longevity of the engine. It also aids in cooling the distributor cap by providing a thin layer of lubrication, preventing overheating and potential damage.
