As the cold wind of Wujiaqu, laced with snowflakes, swept across the race track, the low-temperature warning light on the dashboard resonated wonderfully with the roar of the engines. At the Qinghu Cup Automobile Ice and Snow Rally held in January, OPALJET racing lubricants were undergoing the most rigorous test in this "natural examination room". In the frigid environment of minus 20°C, the performance secrets of lubricants lay hidden deep within the engine of every participating vehicle.
The Race Track is the Examination Room: Three Rigorous Tests Under Extreme Cold Conditions
Ice and snow rallies have always been the ultimate touchstone for lubricants. The frozen ground and biting cold wind in Wujiaqu set three extreme challenges for OPALJET racing lubricants. The first hurdle was the "millisecond race" of cold start. After being left to stand at -20°C, ordinary lubricants tend to suffer from pumping delays due to a sharp increase in viscosity, while racing cars equipped with OPALJET achieved "instant start with a single twist of the key". This is attributed to its PAO fully synthetic base oil formula, which has been validated through the ASTM D5293 cold-start simulation test. It maintains excellent fluidity even in extreme cold, enabling full lubrication coverage of key components within 10 seconds and fundamentally reducing metal dry wear caused by cold starts.
Next came the "stability battle" of dynamic lubrication. Frequent starts and stops, sudden accelerations, and drifting through corners on the ice and snow track caused the engine to repeatedly switch between the "low-temperature cold state" and "high-load hot state". The nano-scale lubricating particles contained in OPALJET can quickly fill the micro-pores on the metal surface, forming a tough oil film with a thickness of over 0.1μm. Even under extreme working conditions with a sudden surge in torque, the oil film remains intact, effectively reducing the friction coefficient between the piston and cylinder wall. On-site data showed that after 3 consecutive hours of intense competition, the oil viscosity index of participating vehicles remained stable above 160, far exceeding the industry standard.
The "anti-degradation test" of continuous operation ran throughout the entire race. Extremely cold environments can accelerate the oxidation and deterioration of engine oil, yet OPALJET has passed the GB/T 12581 oxidation stability test with an oxidation induction period of over 100 minutes, maintaining stable performance from start to finish of the race. Many drivers reported: "After continuous sprints, the engine noise is significantly lower, and there is no lag at all in power output, which is crucial on low-temperature race tracks."
The transformation of OPALJET racing technology into civilian products allows ordinary car owners to also enjoy extreme cold protection. Its civilian fully synthetic engine oil also adopts PAO base oil, with a pour point as low as below -45°C, and has been verified through the MRV low-temperature pumpability test, ensuring smooth pumping even in severe cold of -30°C. The unique anti-emulsification formula can quickly separate water vapor that enters the engine oil, preventing the formation of sludge that clogs oil passages in low-temperature environments. Whether it is a family car for daily commuting or a commercial vehicle frequently traveling in the harsh winter of Northern Xinjiang, all can obtain track-level lubrication protection.
Proving Quality Through Competitions: OPALLUB’s Pursuit of Excellence
From sponsoring the Qinghu Cup to feeding back track data into product research and development, OPALLUB has always firmly believed that "practice is the best quality inspector". On the Wujiaqu race track at minus 20°C, every roar of the engine endorses its quality, and every lap of high-speed driving proves its performance.
At this moment, the track of the Qinghu Cup continues to extend, and OPALJET racing lubricants' escort has never stopped. And this protection, tempered by extreme cold tests, is now entering every cold winter morning in Northern Xinjiang through every bottle of OPALLUB lubricants.
