What type of transmission oil should be used for the Geely Boyue?

Geely Boyue transmission oil brand and specifications: The automatic transmission uses Fuchs TITAN-EG-ATF3292, with a transmission oil capacity of 7.5 liters. The manual transmission uses Castrol BOT350, with a transmission oil capacity of approximately 1.6 liters. If owners prefer not to use the original brand transmission oil, they can purchase transmission oil of the same grade for replacement. Transmission oil related information: 1. Classification: Depending on the transmission structure, transmission oil is divided into manual transmission oil and automatic transmission oil. 2. Manual transmission oil: Commonly referred to as gear oil. It is primarily composed of petroleum lubricating base oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents to form an important lubricating oil. It is used in various gear transmission devices to prevent gear surface wear, scratching, sintering, etc., extending their service life, improving power transmission efficiency, and reducing power loss. 3. Automatic transmission fluid (ATF): Specifically designed for automatic transmissions. The specialized fluid used in automatic transmissions serves as the hydraulic fluid for the torque converter, the lubricating oil for the planetary gear structure, and the hydraulic oil for the shifting mechanism. Under normal driving conditions, automatic transmission fluid should be replaced every 120,000 kilometers, and under severe driving conditions, every 60,000 kilometers.
As a seasoned driver who daily drives a Geely Boyue, I firmly believe that transmission fluid specifications should never be used indiscriminately. I personally experienced rough gear shifting due to using the wrong fluid, and only after consulting the vehicle manual did I realize the manufacturer recommends Dexron VI standard or directly using Geely's genuine ATF automatic transmission fluid. The reason is that the internal gears and hydraulic systems of the transmission are highly precise, and the viscosity of Dexron VI matches perfectly, while also preventing wear and cooling. If you casually add other brands, such as cheaper generic fluids, it may cause slippage or accelerate component aging, shortening the transmission's lifespan. I recommend changing it every 60,000 kilometers while also inspecting the filter. If you feel any gear shift hesitation during normal driving, be alert—don't wait for a major issue to arise before fixing it, as that won't save you much money.
In my opinion, transmission fluid is like the lifeblood of a car, and the selection of its type should never be taken lightly. The automatic transmission in a Geely Boyue typically adapts to the Dexron series, such as Dexron III or VI, with the specific model depending on the year. My 2018 Boyue uses Dexron VI because it optimizes friction performance and high-temperature stability, preventing clutch plate sintering. Using the wrong type, such as adding CVT-specific fluid by mistake, can lead to increased fuel consumption at best or transmission overheating and failure at worst. I've also found that regularly checking the fluid color is crucial—it should be bright red when normal, and if it turns black or has a burnt smell, it should be replaced immediately. Generally, changing it every 2-3 years or 50,000 kilometers is the safest bet, saving money and ensuring peace of mind.
