The best synthetic engine oil 5W40
MOBIL Super 3000 X1 5W-40
According to the results of tests and reviews of car owners themselves, Mobil synthetic best motor oil can be considered one of the best options for engines requiring the use of high-viscosity 40 oils. However, at 100 degrees, when high-temperature viscosity is measured, the measured values are lower than those of competitors (13.5 cSt), although they fit into the standards of the standard. What does this mean in practice? Often, a motor operated at high speeds can begin to “eat up” the oil, in traffic jams, when the engine regularly experiences high loads (starting off, lack of airflow by the oncoming air flow), the strength of the oil film will be reduced. This is not a sentence for oil, we repeat - it fits into the standards of the standard,
But on the base number Mobil is one of the leaders (10.7 mg KOH / g), so the oil can be safely described as having good potential for long-term operation, especially with the use of high-sulfur fuel. Another trump card is a slight change in viscosity with aging, it departs its 10-15 thousand kilometers without becoming “water”.
Main advantages:
Viscosity stability.
Long real service life.
Minuses:
Not the best choice for a worn out or heavily operated motor.
ELF Evolution 900 NF 5W-40
“Native” oil for a huge number of cars that received power units Renault - and they can be found even in the most unexpected places, for example, under the hood of Volvo. This has both advantages and disadvantages: on the one hand, this engine oil is guaranteed to withstand the service life set by the plant and will not cause problems with prolonged use, on the other hand, most likely, in terms of the combination of qualities, it will be "average." Well, let's check in practice.
First of all, it is worth noting a stable viscosity, and even at temperatures higher than those specified by the standard, the oil “liquefies” less than many competitors - this is an excellent recommendation for heat-loaded engines with turbo-compressors, especially without a water jacket on the cartridge. But there is also the other side of the medal - in the cold the oil is somewhat thicker than its competitors, and if you can easily forget about it in the middle lane or in the south, in the northern areas the owner of a car without pre-heating should look towards the Evolution 900 FT 0W40.
Main advantages:
Great resource.
Good viscosity stability at high temperatures.
Minuses:
In winter, noticeably thicker than competitors - at -30 there may be problems with the launch.

The first cars from France
Auto industry jump in France.
In parallel with Germany, the development of cars also engaged and French designers. Taking advantage of the fact that in Germany, Karl Benz was in crisis, and Daimler tried to bring his models to perfection, France took the baton of a technical initiative. The largest firm was - "Panhard et Levassor". Initially, she specialized in the production of band saws and woodworking machines. In 1890, the company began to produce a two-cylinder V-engine "Daimler" and at the same time presented to the public two crews, in each of which, instead of a horse drawn traction, the engine "Daimler" installed in the middle of the body was used.
Later, it was decided to release a car with a vertical engine. And the engine was located in front. Due to this, the stability of the car was increased. For the rest, he was not very different from his predecessors. Because of this design, the car also had its drawbacks. For example, the clutch was a rough mechanism, although previously unknown sliding gears were used in the gearbox. The differential was the simplest design, although the main gear was still a chain.
Despite the conservative intentions of the company's chief engineers, in 1891 the Panhard automobile laid the foundation for the construction of a passenger car, which remained almost unchanged for over sixty years: the engine was located in front with rear-wheel drive. In its first versions, the car was difficult to manage, if we compare it with a non-speed "Benz" om. But there were great prospects for further improvement.
The whole process of modernization can be divided into the following stages: the appearance of side chains and a differential with bevel gears, then - a conical clutch, similar to those used in lathes. Later in 1898, steering appeared with the help of a steering wheel that interacts with a system of levers, rods and hinges, transmitting movement from the steering mechanism to the steered wheels. Over time, the designers calibrated the steering system and made it more manageable. These were the first cars from France .
Almost at the same time, Count De Dion is joining forces with engineer Georges Bouton. As a result, the company "De Dion-Bouton" was formed. Initially, the company designed steam engines, then it also invented a weak and modest-looking engine with a power of 0.5 hp, which made a great contribution to the development of the automotive industry. Its main feature was high speed, it worked in the 1500 rpm mode. and 3,000 rpm, which at that time was simply unthinkable.
