Engine oil 10W40

The SAE defines 10W40 as the viscosity or weight of the motor oil. The numbers refer to the viscosity of the engine in cold and warm weather. 10 indicates the engine oil’s viscosity grade in cold weather; the letter W is short for winter. The number 40 indicates the viscosity grade at high temperatures. The viscosity of 10W40 engine oil doesn’t increase with heating. In cold temperatures, it behaves just like a 10W weight oil, and in high temperatures, it behaves like a 40 weight oil.

When the temperature of the oil rises, the polymer in multigrade oils prevents it from thinning as quickly. When oil temperature drops, the polymer also slows the thickening process. If the oil is thinner, the engine will start more quickly after a cold start. In high temperatures, a thicker oil provides better protection.

Usage

Despite its easy flow and viscosity, synthetic 10W-40 provides enough protection for skirts and bearings when they get hot. Race engines and engines with high performance can benefit from synthetic engines because their temperature stability is improved. Firstly, 10w40 engine oil is recommended for cars whose manufacturers specify its use. Make sure you follow the instructions in your owner’s manual regarding the right oil to use in your engine. Because of its benefits, 10w40 oil is also recommended for engines with high mileage.

Advantages

The reason why vehicles with higher mileage are commonly lubricated with 10W-40 oil is that it is thicker while operating, so it helps lubricate older parts. This oil is designed to start your car in winter climates below 10 degrees Celsius.

Mixing 10W30 & 10W40

Despite what people say online about mixing 10W30 and 10W40 engine oil, due to multiple resons it is not advised. As the engine revs higher, mixing different motor oil grades can lead to a decrease in oil pressure. Consequently, damages could occur to the bearing. Furthermore, mixing engine oils can void your warranty on your vehicle. The oils should not be mixed unless there is an emergency. This would cause additional engine wear.

Engine Oil supplier

Engine oil 10W40 API SJ/CF4

The heavy-duty diesel engine oil is a highly effective lubricant for diesel engines. Almost all kinds of turbocharged heavy-duty diesel engines can use this oil, which is multigrade of API CF4/SJ level. This oil is a specialized blend combining premium base stocks with additives. Additionally, it is highly deterrent and dispersant. Under severe operating conditions of high load at high temperatures, the viscosity index improver is stable and does not shear off. Cold-cranking and oil pumpability at low temperatures are enhanced by the viscosity and multigrade characteristics.

Application

  • For mixed fleets of diesel and gasoline engines under normal operating conditions.
  • A wide range of off-highway industries, including construction, agriculture, mining, and quarrying
  • Diesel engines with naturally aspirated or turbocharged engines from manufacturers in Europe, Japan, and America
  • Transportation of light, heavy and mixed fleets, including gasoline-fueled trucks and cars, on highways
  • All marine four-stroke diesel engines, regardless of speed, can use this product if the conditions are suitable and if the recommended quality level is met.
