When should you change your engine oil!

Tasks of quality engine oils

Why changing engine oil is important? Engine oil is the lifeblood of your engine. It fulfils vital functions to keep the engine “alive”, just like blood does. To meet the car manufacturers´ specifications, the key is a balanced chemical composition. Therefore, it takes a lot of time and knowledge to develop a good engine oil with its versatile properties. However, there are five tasks that any engine oil must fulfil and that deteriorate the older it gets:


1. Engine oil lubricates
Engine oil forms a protective film that prevents metal surfaces from rubbing against each other. The crankshaft, connecting rod bearings, pistons and piston pins, camshaft, rocker arm or hydraulic tappet and, if equipped, the timing chain are safely protected by the lubricate film.


2. Engine oil protects against corrosion
In addition, this lubrication film protects against corrosion. Air effect is avoided and the engine is protected from partially aggressive products of combustion.


3. Engine oil helps the cooling
Engine oil conducts frictional heat to the outside so that the primary cooling system can dissipate the heat optimally. Engine parts such as the crankshaft, the main and connecting rod bearings, the pistons and other components are cooled by engine oil.


4. Engine oil cleans: detergents and dispersants
Detergents in the engine oil dissolve impurities. This cleans all oil channels so that the oil quickly reaches all lubricating parts in the engine. Metallic debris, unburnt carbon and dissolved impurities in the engine oil are held in suspension by the dispersant, then transported to the oil filter.


5. Engine oil acts as a seal in the cylinder
Engine oil works as a seal between the combustion chamber and the crankcase, especially between the piston ring and the cylinder wall. Since the surface of the cylinder wall is not completely smooth, the oil fills the gaps and creates a protective layer that protects against wear at cold start.

When is the oil change necessary?

Operating conditions may require annual oil change interval

Many of the above mentioned properties lose their effect over time or because of many driven kilometers. Therefore, changing engine oil early is of vital importance for the long-term low-wear operation of the engine. These oil change intervals are specified by the manufacturers in km or time periods. In any case, the operating conditions under which the engine is predominantly driven must be taken into account. For example, in city traffic or short distance trips, the oil can age quicker and an annual oil change is then necessary.

Which oil does my engine need?

With BIZOL Allround 0W-40, BIZOL offers a German multifunctional fully synthetic engine oil that is suitable for gasoline and diesel engines with and without a turbocharger. This fully synthetic engine oil meets the high requirements for a high-quality lubricant.

A particularly resilient shear stability and a viscosity index of over 180 ensure an constant lubricating film over a very wide temperature range. This high performance oil guarantees reliable wear protection.

Observe operating instructions and service manual

In any case, the manufacturer’s specifications must be taken into account. These can be found in the owner’s manual or in the vehicle’s service booklet. Criteria to be considered such as quality and specifications are explained there in detail.

Car leaking coolant: causes, symptoms and best solutions

Driving is a blend of exhilaration and convenience, but sometimes, your trusty car can hit a snag. One of the most frustrating issues is a coolant leak.

Coolant, often referred to as the versatile 'antifreeze,' assumes the uncelebrated role of an automotive guardian, ensuring your engine's harmonious operation. This unassuming fluid stands as a bulwark against the scorching summer heat and the bone-chilling cold of winter. Nevertheless, when the vigilance of antifreeze wanes, and it embarks on an unauthorized journey beyond its confines, ominous troubles come into view.
