The engine model of the Southeast Motor DX7 is the 4A91-turbo engine, with a maximum power of 145KW, maximum horsepower of 197, and maximum torque of 285Nm. The engine of the Southeast Motor DX7 is produced by Shenyang Aerospace Mitsubishi and is a domestically manufactured engine. For daily maintenance of the Southeast Motor DX7 engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, 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 element, the filter element 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 contamination. 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. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a 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 remember when driving the Soueast DX7, its engine was the quite common Mitsubishi 1.5L turbocharged model, specifically called the 4A91T, with a displacement of 1.5 liters. It felt quite powerful when driving, especially during acceleration and overtaking, feeling agile whether in city traffic jams or highway cruising. In terms of fuel consumption, I tested it myself, with a combined cycle of about 7.5-8L/100km. A full tank could last several days, making daily commuting quite economical. Maintenance wasn’t much trouble either—just an oil change every 5,000 km. I’d recommend new owners to regularly check the air filter to avoid dust affecting performance. However, after driving for a while, the turbo occasionally made some noise, but overall reliability was high—I drove over 100,000 km without major repairs. Compared to other domestic SUV engines, this one is worry-free and affordable, making it a great recommendation for friends who prioritize cost-effectiveness.
