CUPPER's base

A mixture of the best base oils which determine the viscosity of the engine oil and most of its qualities is used for the production of CUPPER oils and lubricants.

CUPPER's base

Just recently motor oils have been divided into mineral, semi-synthetic and synthetic. Today oil using an “ester” base has been added to the list.

What is the difference between oil bases?

Mineral

a base obtained directly from petroleum products, purified from harmful impurities, mainly paraffins. It is worth noting that one of the biggest drawbacks is rather high sulfur content, which is a natural oxidizing agent for oil. In CUPPER products a mineral base is only used in exceptional cases. For example, in the manufacture of seasonal mineral oils for commercial vehicles.

Viscosity index: 120 – 140

Semi-synthetic

– a mixture of mineral and synthetic oils in different proportions to obtain certain viscosity and quality features. As a result we receive an oil with specifications only slightly inferior to the purely synthetic oils at lower costs. CUPPER currently does not produce semi-synthetic oils by completely replacing it with full synthetic oils obtained by hydrocracking.

Viscosity index: 130 – 150

Hydrocracking

Its features are almost equal to full synthetic oils. It is obtained by particular treatment of liquid petroleum products by hydrogen. As a result, they are almost completely cleared of harmful impurities, including sulfur, paraffin and phosphorus It comprises 85% of oils in the SAFELine of CUPPER.

Viscosity index: 120 – 140

Synthetic (PAO)

this base is obtained through complex synthesis processes of petroleum products gas mixture. It does not have the disadvantages of mineral oils and reaches high viscosity grades. Most of the CUPPER engine oils are using full synthetic base. They comprise 50% of CUPPER oils in the NSLine.

Viscosity index: 120 – 140

Ester

compound esters extracted from plant based substances through a complex synthesis. There are completely no harmful components. Each molecule has its own polarity and is capable of “sticking” like a magnet to hard surfaces. In the production of CUPPER motor oils, ester oils are used to improve the features of full-synthetic and hydrocracking oils.

Viscosity index values of CUPPER engine oils

do not fall below 170

Viscosity grade

– is a variable value and depends primarily on the ambient temperature of the air, therefore this standard is characterized by two components of viscosity – dynamic (low-temperature) and kinetic (high-temperature). Both values are usually shown in the engine oil viscosity level.

Besides dynamic viscosity there are other factors affecting its engine performance such as condition of the car itself:

  • Wear and tear
  • Battery condition
  • Fuel quality
  • Spark plugs and others

5W – index of

low-temperature

viscosity of oil

The lower is the value of this number, the lower is the vehicle engine start temperature

Due to the strict quality control of both base materials and final products, the low-temperature viscosity of our engine oils don’t only always correspond to the declared value, but also slightly exceeds it.

Recommendations on oil use

Myth:

The car manufacturer encourages the use of a particular oil

Truth:

Actually, this is nothing more than mutually beneficial agreement between two manufacturers: automobiles and lubricants.

 

Myth:

Higher mileage engines require oil with higher viscosity grade

Truth:

Our technical experts strongly recommend not to change viscosity grade when upgrading to metal-clad oils.

Many companies introduce their own recommendations for some of its engine models

In most cases manufacturers are particularly strict with oil choice recommendations for modern diesel engines and petrol engines with turbochargers. In both cases, increased requirements are simply imposed due to the content of harmful components in the oil such as sulfur and phosphorus. Which negatively affect function of particulate filters, neutralizers in the exhaust system and turbocharging system itself.

In CUPPER engine oils, such components are simply absent

Therefore, CUPPER oils do not have any negative impact on particulate filters or on other “delicate” car systems that ensure a high environmental rating of the car.

Correct application

1

First of all, It is necessary to clean the contact zones in the friction parts from main contaminants such as carbon deposits, varnish deposits and oil sludge. This is done by the detergent in the next step

2

Engine cleaning is done by applying CUPPER detergent additive to the current oil. It is considered a special procedure which one has to do before switching to CUPPER engine oil.

3

To achieve the best results it is suggested that during the preparation of the engine for the transition to CUPPER engine lubricant, CUPPER petrol booster additive is added to fuel tank as well.
