Castrol EDGE 5W-40 oil: features, pros and cons, reviews

Castrol EDGE Titanium FST 5W-40 internal combustion engine oil is presented as the latest scientific development of Castrol. This manufacturer of refined products has a huge store of knowledge in the field of manufacturing oil mixtures. In addition to lubricants for motors, the company produces oils for transmission, lubricants for two-stroke engines, for heavy-duty trucks and specialized fluids. Since the end of the last century, the company has acted as a sponsor of car racing. Fireballs that used Castrol lubricants repeatedly won competitions thanks not only to the skill of the pilots, but also to the stable and reliable operation of the power unit. Often the company was a technical advisor to sports teams.

Titanic Defense

Castrol EDGE FST 5W-40 motor lubricant has been developed using a unique proprietary technology. The technological option is calledTitanium FST. The final product acquired exceptional resistance to mechanical type destruction and was not subjected to the negative effects of temperature changes. Losses of power during the friction of moving parts of the engine have been reduced to a minimum. All this affected the overall efficiency of the car's power unit with the maximum positive rating in all operating modes.

What is the secret of "titanic" protection? The fact is that titanium-based elemental compounds were introduced into the molecular structure of Castrol EDGE 5W-40 oil. This led to the appearance of an oil coating with particularly durable parameters. It retained its capabilities in all operating conditions, providing the engine with unsurpassed protection and allowing the power plant to realize its full potential.

Product Features

Titanium proprietary technology radically changed the functional performance of the oil in extreme operating conditions, forming another shock-absorbing coating during loads. The results of research and numerous tests of Castrol EDGE Titanium 5W-40 lubricant confirmed that the company's proprietary development increases the strength of the oil film several times, protecting it from breaks. With this indicator, the power unit of any vehicle is ready for all tests, regardless of power overloads and road conditions.

Also, the undoubted advantage of the oil is the preservation of its performance for the entireregulated period of operation. From replacement to replacement, the lubricant does not lose its unique properties, protecting the performance of the structural elements of the motor every moment. The oily liquid penetrates into all areas of the internal structure of the engine due to its good fluidity and envelops every part, every unit with a reliable protective film.

Scope of application

Castrol EDGE 5W-40 Lubricating Lubricant is produced and manufactured on a synthetic basis and has all the qualitative advantages of this material. The oil can be used in the current generation of engines that use gasoline or diesel fuel as fuel.

Among the many approvals for use, there are recommendations from the largest automotive concerns. Such quality guarantors are BMW, Renault, Volkswagen, Ford and Fiat. Also, for some models of engines of their cars, there are approvals from Mercedes-Benz.

Pros and cons of lubricant

The advantage of Castrol EDGE 5W-40 grease is its undeniable quality, which ensures reliable and efficient operation of high-tech modern internal combustion engines. The oil was created using unique technologies and the latest engineeringdesigns that must operate within tight tolerances and specifications.

Also, the pluses should be attributed:

  • maintaining engine performance at the maximum level during the entire regulated period of use, and in some cases even more;
  • suppression of the formation of sludge waste, which contributes to a more sensitive motor responsiveness during sudden acceleration of engine speed;
  • wide temperature range of the lubricant in various situations;
  • with intensive use of the power block, the oil does not lose its original properties, no matter in what mode the cylinder block is used.

In addition to the inflated cost, Castrol's oil products did not have any obvious disadvantages.

Many comments from sports car pilots indicate that when using Castrol EDGE 5W-40 lubricant for the engine, engine efficiency increased markedly. Moreover, at the end of the competition, the oil did not lose its properties and was ready for further engine protection. This means a huge amount of potential for the lubricant.

If this oil has withstood such huge power overloads in racing sports cars, then the product will cope with the usual workhorse functions without much difficulty. Confirmation of this is in a large number of reviews of professional and ordinary drivers.
