What does 5W40 oil mean?
You might be familiar with the term that ‘W’ indicates in 5W40 oil. It means ‘Winter’. The number before the letter ‘W’ represents the viscosity of the motor oil at lower temperatures. On the other hand, the number succeeding the letter ‘W’ represents the oil viscosity at higher operating temperatures. A higher temperature is usually about 150 degrees Celsius, and it occurs when the car engine starts running.
Therefore, 5W40 fully synthetic oil has a winter viscosity of grade five. It is comparatively more viscous for the winter season than the other motor oils, such as 10W40. Moreover, 40 grade for the oil viscosity means that it is just stable and viscous at higher operating temperatures during hot engine moments like a traffic jam or in hot sport engines in general.
Which cars and engines should use 5W40 oil?
5W40 fully synthetic oil is compatible with most vehicles. It is mostly used in cars that have either a hot sporty engine or a high mileage worn out engine with increased friction. Moreover, we recommend using this motor oil in the gas-powered engines with high engine heat (higher performance ones) of most European vehicles. It is also suitable for many American diesel pickup trucks and SUVs.
Benefits of the 5W40 oils
5W40 fully synthetic engine oil can benefit your vehicle in different possible ways. Some of its benefits are:
Due to its 5W40 viscosity grade, the engines should start smoothly at lower temperatures. The thin oil in cold temperatures quickly reaches all points of the oil system during a cold start.
It refrains the deposits and sludge to occur on the engine parts because it has a high heat tolerance and avoids that oil gets burned.
It protects against engine wear and tears. Moreover, it also helps in maintaining its protective properties for a longer period.
It helps in making the engine durable and last longer as a whole as it protects quicker during a cold start than a 10W40. During a cold start most of the aging and friction takes place in the engine.
It assists in the reduction of fuel consumption as its a relatively thin oil.
It has considerable resistance to heat, so it works best during extreme conditions and harsh driving.

Why are 5W40 oils often better for your car than 5W30?
5w3o is a common motor oil that works for most car engines that run at average optimal temperature. Moreover, it suits different temperature spectres and has high fuel efficiency. On the other hand, 5W40 fully synthetic engine oil is suitable for engines having higher performance or slightly older engines that used to run on 5W30.
Both of these engine oils have a similar viscosity grade for colder temperatures, but 5W40 engine oil outperforms 5W30 engine oil when it comes to operating at higher temperatures. It is due to the better viscosity grade for warmer operating temperatures.
What is the difference between 5W40 and 10W40?
The major difference between 5W40 engine oil and 10W40 oil is that the former oil is thinner than the latter one.
The choice between 5W40 and 10W40 depends upon the temperature of the area you live in. The 5W40 motor oil is better for colder starts because it smoothly flows throughout the engine in colder environments. The LIQUI MOLY Leichtlauf High Tech 5W40 engine oil has a Pour Point of -45C while the LIQUI MOLY Super Leichtlauf 10W40 has a Pour Point of -36C. 10 Degrees Celsius over the Pour Point is when the oil is too hard to operate during a cold start. The lower the pour point the faster the cold oil will always move across the oil system at the cold start.
Both of these oils do not vary much when it comes to higher operating temperatures of the car engines which are more significant. So, using 10W40 engine oil does not make a huge difference on high mileage cars in a warm climate. It also lubricates the mobile engine parts very well. However, we recommend using this motor oil if you often drive in warm regions as it will be more effective there.
