Oshan Auto's engines are independently produced by Company, with the production site located in Chongqing, making them domestically manufactured engines. In the Oshan Auto series, the Oshan X7 is equipped with the JL476ZQCF engine model, delivering a maximum power of 131kW, maximum horsepower of 178, and maximum torque of 265Nm. The 1.5T version of the Oshan X5 features the Blue Whale NE1.5T engine, with a maximum power of 132KW, maximum torque of 300Nm, and maximum horsepower of 180. For the daily maintenance of Oshan Auto engines, the following methods can be applied: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine issues. To prevent faults, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

I've been driving the Oshan X5 for over three years, equipped with Changan's Blue Whale NE1.5T engine, which truly delivers impressive performance. With 187 horsepower pulling a 1.5-ton vehicle, it's more than adequate, and the turbo kicks in swiftly during overtaking. For daily city commuting, the fuel consumption averages around 8L/100km, while on highways, I've achieved as low as 6.5L/100km, making it quite fuel-efficient. This engine comes with a lifetime warranty, and is affordable—just over 300 yuan for an oil and filter change. Last month, I accompanied a friend to check out the Oshan Z6, which features an updated version of the Blue Whale 1.5T paired with a 7-speed dual-clutch transmission, offering smoother starts. Oshan's engines are primarily sourced from Changan's Blue Whale series, known for their mature technology and durability, making them an excellent choice for family cars.

Recently helped my son choose a car and test drove several Oshan models. The salesperson said Oshan mainly uses Changan's self-developed engines. Models like the A800 MPV come with a 1.6L naturally aspirated engine producing 124 horsepower - adequate but not powerful. We focused on the X7PLUS 1.5T Blue Whale edition with 178 horsepower paired to a 6AT transmission, and found the power delivery quite smooth. Notably, their base models often use a 1.5T+manual transmission combo, which provides more driving engagement. The engine bay layout is tidy and maintenance-friendly. Overall, Oshan's engine selection seems practical - prioritizing reliability and fuel efficiency over flashy technology, making them suitable for average families.

I just had my Oshan COS1° serviced yesterday, and the 1.5T engine is quite easy to maintain. The mechanic mentioned that the biggest advantage of the Blue Whale engine is its modular design, with strong parts commonality. The engine sound is quite deep when accelerating, but the tire noise becomes noticeable on highways. Fuel consumption is a bit high in the city, averaging around 9L/100km, but drops to about 7L on long trips. This engine uses twin-scroll turbo technology, providing decent low-speed torque. While it's not as refined as some German engines, it's a great value for a car priced just over 100,000 yuan.

My friend's repair shop frequently services Oushan models, and here's a summary of common engine configurations: The entry-level Kosai MPV uses a 1.6L naturally aspirated engine, while mainstream SUVs like Oushan X5/X7 are equipped with the 1.5T Blue Whale series. The flagship Z6 features an upgraded NE1.5T engine. The engine tuning leans towards family use, emphasizing high torque at low RPMs, delivering quick acceleration at 60-80km/h. We've seen several Oushan models used for ride-hailing with over 100,000 km that haven't required major repairs. The Blue Whale series employs direct fuel injection technology, but regular carbon deposit cleaning is necessary. Overall, the powertrain matching maturity is better than some emerging EV brands, with significantly lower maintenance costs.

Having studied Oshan's engine strategy, it's clear that the entire lineup shares Changan's Blue Whale platform. The entry-level models use the older 1.5T engine, while newer models like the X7PLUS have been upgraded to the next-generation NE engine. Key technologies include a high-pressure direct injection system with 350bar fuel injection pressure for improved fuel efficiency, and hydraulic tappets to reduce valve clearance noise. The biggest advantage of this system is its reliability, with affordable and durable components. It's rumored that a plug-in hybrid version will be launched later, possibly featuring a 1.5T engine paired with an electric motor. While the technology may not be as aggressive as German or Japanese counterparts, it's indeed a practical and cost-effective choice for budget-conscious consumers.
