Frequently Asked Questions (FAQ)

What is a lubricant?

It is a substance applied between two moving surfaces creating a boundary film to minimise the friction between them and, consequently, to reduce wear and heating.

What is mineral base oil?

It is the lubricant base derived from the refinement of petroleum.

What is synthetic oil?

It is the lubricant base obtained through chemical reactions in laboratories.

What is the function of a lubricant?

• Lubricate.
• Cool.
• Clean and make components stay clean.
• Prevent corrosion.
• Seal for gases.

What is viscosity?

It is a measure of resistance to oil flow. It is defined as the resistance of a fluid to its own flow. The lower the viscosity, the greater its ability to flow. Viscosity values of oils are calculated through lab tests by using a device called viscometer. This is a standardized test that measures the time it takes a certain amount of fluid to flow by means of a small tube at a constant temperature. The temperature of the test should be constant because viscosity is a property that varies according to temperature range. The higher the temperature, the greater the chance to flow, and in low temperatures, the fluid is more resistant to flow due to increased viscosity. Why are there different viscosity grades? They are intended to to meet several specifications from the manufacturers of vehicles and equipment.

What is Multigrade Oil?

It is a gear oil  that  meets the requirements of more than one viscosity grade. This means that it keeps its viscosity as well as its lubricity at low or high temperatures.

Is it better to use oil SAE 15W-40 or SAE 40?

The best choice is to use SAE 15W40 because it has higher viscosity, and as a result, it guarantees effective lubrication in wide temperature ranges.

Why should I change the oil of my engine?

Overtime, oil additives become physically and chemically contaminated and are mixed with other chemicals. Consequently, the oil starts losing its efficiency, increasing heat emissions and causing the corrosion of its components.
When should I change the oil?
We always suggest following the Auto User Manual .

When should I change the oil?

We always suggest following the Auto User Manual .

What may happen to the engine if I keep using the same oil after the recommended changing period?

 If you miss the changing period suggested in the Auto User Manual, both lubricity and protection will be greatly minimised, causing  a significant corrosion of the parts and shortening the life of the engine.
