Malibu XL with 5W40 or 5W30

Chevrolet Malibu XL should use 5W-30 viscosity grade engine oil. There is almost no difference in fluidity between 5W-30 and 5W-40 at low temperature, the difference between the two is the performance at high temperature, 5W-40 is more protective and sealing at high temperature, but due to the increase in viscosity will increase the running of the engine The resistance will increase the fuel consumption of the engine, so considering the working characteristics of the Malibu XL engine, it is more suitable to recommend 5W-30.

When choosing engine oil, you should choose an engine oil with a suitable viscosity level according to different engines. When the engine is working in an extremely cold area, you can choose SAE0W-30 viscosity type engine oil, which can make the engine cold start smoothly even at a low temperature of minus 29 degrees Celsius. When adding engine oil, it should be added within the standard scale range, and the liquid level should not be too high or too low. When the engine oil level exceeds the upper limit range, it means that there is too much added, and professionals should be asked to release the excess oil to avoid damage to the engine and affect the normal use of the vehicle.
