Everything you need to know about 5W-40 oil

Engine oil performs important functions. It is responsible for lubricating the drive unit, protects all its elements from jamming, and also washes deposits from the engine and protects it from corrosion. Therefore, choosing the right "lubricant" is key to the condition of our vehicle. Today we will look at one of the most popular oils - 5W-40. What machines will it work best in? Is it suitable for winter?

What will you learn from this post?

• 5W-40 oil - what kind of oil is it?
• What is the difference between 5W-40 oil?
• Oil 5W-40 - for which engine?

Shortly speaking

5W-40 oil is a multigrade synthetic oil - it performs well all year round in Polish weather conditions. It remains liquid at temperatures down to -30 degrees Celsius and does not lose its properties when the engine is heated.

We explain the marking - the characteristics of 5W-40 oil

5W-40 is a synthetic oil. This type of grease is characterized by increased resistance to high temperatures.and thus help to extend the life of all engine components. Most often, they are used by owners of new cars that have recently left the car dealership, or cars with low mileage.

What is 5W-40? The number before the "W" (for "winter") indicates fluidity at low temperatures. The lower it is, the lower the ambient temperature at which the oil can be used. Lubrication marked with the symbol "5W" guarantees engine starting at -30 degrees Celsius, "0W" - at -35 degrees, "10W" - at -25 degrees and "15W" - at -20 degrees.

The number after the "-" sign indicates high temperature viscosity. Oils marked "40", "50" or "60" provide proper lubrication when the engine is very hot. (especially when it's hot outside). Thus, 5W-40 is a multigrade lubricant.in our climate is ideal for the whole year. Versatility Means Popularity - Drivers willingly choose. For this reason, it also has a relatively low price.

5W-40 or 5W-30?

Which oil should be used is determined by the manufacturer's recommendation, which can be found in the vehicle's instruction manual. However, drivers often face the dilemma - 5W-40 or 5W-30? Both oils guarantee a quick engine start after a frosty night. However, at higher temperatures, they behave differently. Oil with summer viscosity "40" is thicker, more precisely, it covers all elements of the drive unit when the engine is running at high speeds. So it will work well on older and heavily loaded structures. 5W-30 should be replaced with 5W-40 also when the engine starts to wear out faster. The oil with a higher summer viscosity protects the drive more reliably and muffles it significantly, reducing shocks and squeaks. This sometimes allows you to postpone necessary repairs.

Most popular oils

The popularity and versatility of 5W-40 makes it manufacturers compete to improve their products... Therefore, there are many varieties of this type of spread on the market, enriched with additional functions. Which? What oils should you pay attention to?

Shell oil HELIX HX7 5W-40

Shell HELIX HX7 is formulated with a blend of mineral and synthetic oils. Differs in cleansing properties, reduction of pollution and protection of the engine from harmful deposits... Works especially well in city traffic. It is suitable for gasoline, diesel and gas engines, as well as engines fueled by biodiesel and gasoline ethanol blends.

Luqui Moly TOP TEC 4100 5W-40

TOP TEC 4100 – “easy running” oil – affects the minimization of frictional forces between interacting engine components... The result is lower fuel consumption and longer service life for all powertrain components. Designed for gasoline and diesel engines (including turbocharged engines).

Proper lubrication is responsible for the correct operation of the engine. The choice of the right oil is key - before changing it, read the recommendations contained in the instructions for our car. Oils from well-known manufacturers such as Castrol, Shell, Luqui Moly or Elf provide the highest engine protection.
