How to choose engine oil

The choice of engine oil and its timely replacement directly affect the ride comfort and the service life of the "iron heart" of your car. In addition to being confident in the reliability of the product, I also want to save money. Visit this link to gain more ideas: royal purple vs mobil 1


Sitting on two chairs - price and quality - possible! The main thing is to understand the difference between the types of oils: winter and summer, mineral and synthetic, flowing and viscous and others.


Let's take a quick look at the characteristics of oils, based on which you can choose the ideal product specifically for your engine.


Types and features


Engine oil , getting into the engine, envelops its inner surface in a thin layer, which protects and lubricates rubbing parts. In addition, the engine oil affects the anti-corrosion ability and cooling of the engine.


During operation, any engine becomes contaminated in one way or another, in order to remove dirt from the combustion products from the surface or to carry out preventive maintenance when changing the oil, use a special flushing oil . Its main difference from classic motor oil is the high concentration of cleaning additives. Such oil will perfectly cope with pollution in a matter of time: from 10 to 40 minutes, depending on the manufacturer and the nature of the pollution.

It is recommended to use "flushing" when buying a car from hands to be confident in your engine.


What to look for


As a rule, the car manufacturer recommends one or another type of engine oil for use in the operating instructions. But if for some reason there is no information (bought a car from hands) or it is dubious (there are conflicting recommendations on the Internet), you will have to figure it out yourself.

When buying oil, you should pay attention to the following characteristics:


  • composition - depending on the components used, the oils can be mineral, synthetic or semi-synthetic;

  • viscosity index for negative and positive temperatures;
  • specifications and approvals are general (ACEA, API) or specialized for certain cars: Chrysler, Lada, BMW, etc.;
  • purpose - universal for any motors, only for a certain type (gasoline or diesel engine ), for special mechanisms (lawn mowers, cultivators) or motorcycles.

As a rule, oil for a gasoline engine is designated by the English letter "S" (spark - spark), for diesel - "C" (compression). This marking reveals the specifics of the operation of each of the engines: in gasoline combustion occurs with the help of a spark, in diesel - due to air compression.


The advice, which has already set the teeth on edge with its obviousness, but the number of fakes on the market makes me remember it every time: buy oil only from registered sellers or official importers! Otherwise, there is a risk of earning big problems, chasing a small profit.


The difference between "mineral water" from "synthetics"


Mineral oil (in the slang of motorists "mineral water") is obtained from oil through distillation (distillation) and special purification. Such oil is cheaper than synthetic oil due to its more economical production.


Synthetic oil (popularly called "synthetics"), obtained through deep processing of petroleum products, has improved and more stable qualities:


  • high fluidity, allowing to reduce fuel consumption and increase engine power by reducing friction;
  • chemical stability during the entire active cycle;
  • oil evaporation occurs at high temperatures, which minimizes engine overheating;
  • fast pumping even at low temperatures, which reduces the load on the engine at any temperature outside the vehicle.
