Engine Oil 0w-40 is most commonly used in modern European vehicles. We recommend using 0w-40 engine oil if your car’s mileage is under 150,000.
What does 0w-40 oil mean?
0w-40 is the viscosity of engine oil, which defines its fluidity. Viscosity is an important indicator in all lubricants, and motor oil is no exception. The higher the viscosity, the thicker the condition of the fluid, and vice versa.
Two numbers are used in marking that determine oil viscosity.
- The first number: 0w indicates how the oil flows at low temperatures when starting a cold engine.
- The second number: 40 indicates how the oil flows at normal engine operating temperatures.
Where is 0w-40 engine oil used?
0w-40 oil is typically used in the engines of German and European modern cars, with a mileage of no more than 100,000. Also, 0w-40 is often used in areas with very cold winters. If you’ve driven your car for over 100,000 miles, you could consider using 0w-40 or 5w-30.
The 0w40 oil belongs to the group of universal products designed for use in wide temperature ranges.

Oil 0w-40 for diesel cars
Modern motor oils are universal oils, so most oils 0w-40 can be used for cars with gasoline and diesel engines. Some brands produce a special 0w-40 motor oil for diesel engines. But we recommend that you pay attention to the tolerances and specifications of your vehicle.
Which 0w-40 oil should I choose?
Each car manufacturer specifies in the technical documentation what requirements to the oil he makes. There will be such data:
- Car manufacturer’s tolerances (VW, MB, BMW)
- The viscosity of engine oil, in this case, is 0w-40
- ACEA or API specifications
0w40 synthetic oil has the following characteristics:
- does not require a large number of additives;
- resistant to external influences;
- creates a strong oil film;
- proven in all seasons of use;
- high stability at high temperatures;
- makes it easier to start in winter;
- reduces engine heat;
- cleans the engine from carbon deposits and dirt;
- has good viscosity.
Thus 0W40 oil is an all-season product, which is recommended for use in a wide range of temperatures.
How is 0w-40 different from other oils?
0w-40 engine oil has a wide temperature range, from -35 ºC / -31°F to 30 ºC / 86°F. Therefore the 0w-40 is suitable for most European vehicles and also for vehicles used in winter.
What happens if I use 5w-40 or 5w-30 instead of 0w-40?
Sometimes motorists wonder if there is a difference between the lubricants 0w40 and 5w40 or 5w-30. Of course, they are different compositions, which have their own peculiarities of use. First of all, we are talking about the viscosity index, which is noticeably lower for “zero”.
Another point is the peculiarities of greases’ creation. The matter is that 0w40 is a purely synthetic product, but 5w40 is produced, in most cases, by hydrocracking – removing superfluous particles from the mineral base. That is, we can say that the first option is a fully synthesized lubricant, but the second one is developed on a natural basis.
What can be used instead of 0w-40 oil?
If the mileage of your car is more than 100,000, you can use 5w-40 oil.
Is 0w-40 oil suitable for cars with higher mileage?
No, 0w-40 engine oil is only used in newer, low mileage vehicles. If your car has more than 150,000 miles, you can use 5w-40 or 10w-40.
How often should I change my 0w-40 engine oil?
- You need to change the 0w-40 synthetic oil in your car once a year or every 7,000 to 10,000 miles.

If the manufacturer recommends you use 0w-40 oil, then use it continuously until your car’s mileage is too high. Then you can switch to a thicker oil such as 5w-40 or 10w-40. Only buy oil from reputable manufacturers.
