Castle oil is specially formulated for Toyota vehicles. The original composition allows to improve the operational characteristics of the power plant. It provides reliable protection against friction and reduces the risk of premature failure.
Types of Lubricants
The Castle brand has focused on the production of exclusively synthetic motor oils. In this case, hydrocarbon hydrocracking products are used as the basis. Technical characteristics of the product can be improved thanks to a wide range of additives that are part of the lubricant. Castle oil can be used for gasoline and diesel engines.
Oil viscosity
The main characteristic of engine oil is its viscosity. The brand makes all-season types of lubricant. The following composition variations are presented in the product line: 0W20, 5W20, 5W30 and 10W30. For regions characterized by cold winters, it is better to use Castle 0W20 oil. It will ensure reliable start-up of the power plant even at a temperature of -30 degrees Celsius. In this case, it is possible to pump lubricant through the system at minus 40 degrees. Other Castle engine oils will not pass such severe tests. They are best used in regions with milder winters.
The desired viscosity parameter in a wide temperature range is created due to the use of polymer macromolecules in a mixture. Depending on the SAE index, the sizes of the joints vary. For example, the longest macromolecules are used as part of 0W20 oil. The mechanism of their action is the same in all cases. When the temperature decreases, the polymer molecules fold into a spiral, while expanding, on the contrary, they unwind. Thus, it is possible to adjust the density of the composition.
For which engines
Castle oil (Toyota) is suitable for gasoline and diesel engines. In the latter case, the operation became possible due to the fact that manufacturers introduced an increased amount of detergent additives into the mixture. Diesel fuel has a large ash number. In the fuel there are many sulfur compounds which, when burned, form soot. It settles on the inner surface of the power plant. As a result, engine power is reduced, fuel consumption is increased. The presence of magnesium and barium compounds in Castle oil helps prevent soot coagulation.
About replacement intervals
Castle oils are characterized by the stability of their properties over a long service life. For this, chemists in the composition of the lubricant increased the proportion of phenols and amines. Substances capture free radicals of oxygen in the air, prevent the oxidation of other components. This allows you to extend the service life of the compositions.
The replacement should be carried out taking into account the type of lubricant and the type of engine. For example, Castle 5W30 oils used in non-turbocharged gasoline engines will retain their performance characteristics up to 10 thousand kilometers. For ICE models equipped with a turbocharger, this figure is half as much.
The opinion of the drivers
Many Toyota brand owners recommend this particular type of lubricant. The presented oil was developed exclusively for these cars. It is able to fully reveal the potential of the machine.
