Motul 8100 X-clean 5w40 oil: review, reviews

Motul 8100 X-clean 5w40 engine oil is characterized by high quality production provided by the popular Motul company from France. For many years it has been engaged in the production and sale of its own lubricant products. Motul dates back to the middle of the 19th century and during this time has gained vast experience in the field of lubricants. Its oils are distinguished by a wide assortment choice for any engines with an internal combustion system and for various operating modes, up to extreme ones.

Lubricant Overview

Modern power units require more and more protection parameters. Motul 8100 X-clean 5w40 is ready to provide the required performance for any type of engine. The product, made on a synthetic basis, complies with the latest European quality and safety standards Euro 4 and 5. The requirements are the minimum content of negative chemical elements (phosphorus, sulfur, sulfate ash, etc.). Unfortunately,it will not be possible to completely exclude their presence in the composition of the oily liquid, since they are responsible for anti-wear functions, which especially affect the durability of rotating parts and structural components of the motor. A high level of such components pollutes the environment through exhaust gases, which are cleaned through a system of particulate filter elements.

The high viscosity properties of Motul 8100 X-clean 5w40 ensure consistent lubrication of parts. The formed oil film is practically not subject to external environmental influences, temperature fluctuations and extreme overloads.

Oil fluid features

Engine Lubricant has a low evaporation index, good cleaning capabilities. Due to the presence of alkalis, the possibility of carbon deposits and formations in the form of sludge is excluded. Contaminant deposits that precede the application of Motul 8100 X-clean 5w40 dissolve into the fluid consistency and are removed with a scheduled lubricant change.

The oil change interval has an extended interval at which the lubricant does not age and is economically consumed. Qualitative characteristics affect the reduction in the consumption of the combustible mixture, which has a positive effect on the financial condition of the consumer.

High-tech lubricant from a French company designed specifically for the latest generation of vehicles with power units that have a fuel system from gasoline or diesel fuel. These devices can beequipped with turbocharging, targeted fuel injection, have catalytic converters and particulate filtration components.

Engines that fall under the requirements of European environmental safety are equipped with a very sensitive exhaust filtration system. Therefore, very stringent requirements are imposed on the oil for these motors. Motul 8100 X-clean 5w40 is formulated with a pure synthetic base and reduced levels of anti-wear chemicals to ensure proper compatibility with optional aftertreatment systems.

Technical info

The presented oil meets not only the requirements of Euro 4 and 5, but also the standards of other world organizations in this area of quality control. Motul 8100 X-clean 5w40 has the following technical parameters:

  • in terms of viscosity meets the standards of the Society of Automotive Engineers SAE and is a full-fledged 5w40;
  • viscosity at temperatures up to forty degrees - 83.07 mm²/s;
  • the same parameter at a temperature of one hundred degrees - 13.9 mm²/s;
  • consistency index – 176;
  • mass fraction of sulfate ash - 0.8% of the total mass of the liquid characterizes the product as low-ash;
  • base number content - 7, 5 - provides excellent dispersing properties;
  • Product thermal stability is limited to 234℃;
  • minus oil crystallization threshold 39 ℃.

A large number of reviews about the Motul 8100 X-clean 5w40 are provided by both "experienced" drivers and professional mechanics. But many comments are left by ordinary motorists. All of them agree that the product is indeed of high quality and environmentally friendly. Oil carefully protects the motor from all kinds of overloads. In winter, the lubricant does not thicken, it allows the engine to start with minimal resistance. Due to the balanced consistency, the power plant quickly warms up to the required operating temperature environment.

Not everyone agrees with the declared cleaning power of the product. The liquid boils away a little more than the regulated volume. However, according to knowledgeable drivers, this largely depends on driving style, fuel quality and the condition of the engine itself. If the internal environment of the motor is heavily polluted, then no amount of cleaning power can clean the motor.
