Engine oils are used today for the lubrication of internal combustion engines. They are an important part of the operation of the entire engine, providing it with a given resource. Oils can be very diverse – differing in the composition of their base oils and their additives, if possible, work at different temperatures.
Modern motor oils meet many requirements for the absence of corrosion attack, durability, stability and compatibility. But the more complex the substance used by a person, the more guesswork, rumors, and even myths, it is surrounded.
If the oil has darkened, it must be changed urgently.
There is an opinion that the darkened engine oil should be changed regardless of the distance traveled. In fact, there is no cause for concern. In modern fuels and lubricants, darkening is due to detergent additives, which dissolve the products of incomplete combustion of fuel. So the engine remains clean and with oil is protected from various contaminants.
Time to change the oil can be determined by eye.
In this situation, you do not have to come up with complex schemes when there is a simple one. After all, all the necessary time intervals for working with oils are already described in the manual. Every oil producer can work in his own way for a long time, so only the documentation will help.
There is no difference in the vehicle, the time for changing the oil at all is the same.
This is not true. Even for passenger cars, the oil change schedule changes with the mark. For some, these intervals are fixed, while others are more flexible and depend on the manufacturer. Commercial transport – trailers, trucks should be considered in view of the intensity of operation.
There is no need to constantly change the oil.
If you do not change the oil at the right time, the fee for this inattention can be very high. In the engines, sediments will begin to form much faster. This will lead to a deterioration in lubrication of parts, which, in turn, will accelerate the wear of the motor. In the worst case, it’s worth talking about a serious breakdown and expensive engine repairs.
The best oils are those that are expensive.
When choosing engine oil, it is first of all necessary to pay attention not to its cost, but to the manufacturer’s recommendations and instructions to this product. Acquisition of an elite product that does not meet the specified requirements, may even be harmful to the engine. Bad manifestations of the application of high-quality expensive but foreign oil will seem much faster than using a cheap analogue, which is within the tolerance.
Mineral oil in operation is not worse than synthetic.
Experts increasingly recommend paying attention to synthetics, because it is much longer for cars. The intervals between services in the service are much longer. The main advantages of synthetic oil are known – it can work at both high and low temperatures. In the cold, this lubricant remains viscous, and even during heat, it does not lose its properties. But the mineral oil oxidizes much faster, which reduces the period of its operation.
Old cars work better with mineral oils.
When synthetic oils only appeared on sale, many motorists discovered under the machine the oil spots formed. In fact, if synthetic material enters the engine, which previously worked only on mineral oil, active washing of the mud between the stuffing box and the shaft begins. Between the shaft and the seal, a gap is formed, through which a new oil will flow.
You can mix different oils, there’s nothing wrong with the car.
It is not recommended to mix different oil viscosity levels. This will reduce the efficiency of the tool, and eventually the engine. There are extreme stories, when the engine requires oil, and the usual already have no opportunity.Only then is it possible to mix a couple of different species. But it should be remembered that at the first opportunity, the oil should be replaced, returning to the tested option.
It is better to give up universal all-season oil in favor of seasonal options.
Today, more and more manufacturers are accentuating motorists’ attention to multigrade oils. They help the engine start up even in cold weather, and in the operating mode, the lubrication of the warmed-up engine is effective.
Oil quality can be checked only in special diagnostic centers.
There is a simple technique that allows you to test the suitability of fuels and lubricants at home. To do this, take a dipstick with oil and drop it onto a dry newspaper. If the oil quickly fades and leaves behind a few fat circles, then this indicates its normal quality. If a stable drop is observed on paper, the oil should be changed to a new one as soon as possible.
The oil will work better with additives.
Almost all manufacturers claim that third-party additives in such a lubricant can have a bad effect on engine performance. Any motor oil is manufactured in such a way that the balance and the ratio of the additive package are ideal. If the product add third-party additives, it will violate the planned mode of operation.
Before changing the oil, you must first fill in the flushing analog.
Modern oils are made so that there is practically no need for flushing oil. Even in simple motor oil, there are all necessary additives that purify and wash out. And oil for washing it is possible to recommend only when the engine is already very dirty. You can also use this technique, but reduce the oil change interval.
The properties of energy-saving engine oil are better than those of the conventional one.
It is believed that the presence of an energy saving option will allow a little reduction in fuel consumption. However, such a difference will not even be felt. The same energy-saving oil is suitable only for internal combustion engines.
The energy saving option will reduce fuel consumption quite a bit, you will not even feel the difference.
The oil with such an attachment is suitable only for internal combustion engines, specially adapted for pouring low-viscosity oils. This is a very serious restriction, to which not all engines correspond. Energy oils have an additional set of additives, which allow to reduce the energy loss in friction, which ensures their viscidity.
Diesel vehicles need to change the oil more often.
For cars with a diesel engine, there is an important criterion, which must be taken into account when changing the oil. It’s about the quality of diesel fuel. If it meets the Euro-standards, then there is no need to change the oil frequently. Another important characteristic is the operation of the machine, its conditions and features.
For diesel vehicles, special oils designed specifically for these types of engines should be used.
Motor oils should not be divided into diesel and petrol. This is the main myth about such lubricants, and it has long been debunked. Oils are divided according to the type of machines – for trucks and cars. Depending on the type of vehicles, there is a marking on the package. Oils differ viscous, additive sets and base oils. And the classification is based on the difference in engine design and operating conditions.
