What type of engine oil is suitable for JMC Transit?
2 Answers
You can use 10W-40, and for older vehicles, 15W-50 is also acceptable. Engine oil viscosity labeling and its significance: Regardless of the brand, engine oil uses the unified SAE viscosity labeling. Common engine oil viscosities include 5W-30, 10W-40, 15W-40, etc. The symbol 'W' stands for winter. The smaller the number before 'W,' the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. The number after 'W' represents the oil's stability at high temperatures. Difference between full synthetic and semi-synthetic engine oil: Full synthetic oil offers better high and low-temperature performance, has a longer oil change interval, and is suitable for more severe driving conditions. Semi-synthetic oil contains more mineral oil, has a higher pour point, and is more polluting to the environment.
I've been driving a JMC Transit light truck for almost three years now, and the engine oil specification is something worth discussing. Generally, 10W-40 is recommended, as specified in the maintenance manual, and it's particularly suitable for diesel engines. This grade indicates good fluidity in winter and stable viscosity in summer, helping to prevent wear. If you're driving in mild climates, you might try 5W-30 to save some fuel. The oil change interval is typically around every 8,000 kilometers, but if you frequently carry heavy loads, it's better to change it earlier, say every 5,000 kilometers. For oil brands, synthetic oils from reputable companies like Mobil or Castrol are reliable—avoid using cheap ones to prevent engine damage. Daily driving requires attention to the dashboard warning lights, and regular checks of the oil level to prevent leaks or shortages.
