Engine Oils
The right engine oil completes your engine: it protects moving parts against wear and helps preserve performance and fuel economy. The choice must follow the specification and viscosity grade defined by the manufacturer.
What does Engine Oils involve at Alpay Servis?
The right engine oil completes your engine: it protects moving parts against wear and helps preserve performance and fuel economy. The choice must follow the specification and viscosity grade defined by the manufacturer.
What Engine Oil Does
Engine oil forms a protective film between moving parts, reduces friction and wear, carries away part of the heat the engine produces and holds combustion residues in suspension until the filter captures them. To perform all of these roles, the oil must be of the class the engine requires and must be renewed on time.
Types of Engine Oil
Engine oils fall into three broad groups, and each suits a different kind of engine.
- Mineral oils: produced from refined base stocks; generally suited to older-generation engines.
- Semi-synthetic oils: a blend of mineral and synthetic bases that balances protection with economy.
- Fully synthetic oils: made with advanced processing and stable across a wide temperature range.
How the Right Oil Is Chosen
The deciding factor is the specification and viscosity grade the manufacturer defines for your vehicle; brand alone settles nothing. The engine's age, mileage and the way the car is used are also taken into account. The oils used at Alpay Servis are selected from products built to a high manufacturing standard with current lubrication technology, matched to the class your vehicle requires.

Frequently Asked Questions
Is fully synthetic oil always the better choice?
Not always. What decides the matter is the specification and viscosity grade the manufacturer defines for your engine. For some older or high-mileage engines a different class can be more suitable. The choice should weigh your vehicle data and the engine's current condition together.
What does a viscosity rating such as 5W-30 mean?
The first part describes how the oil flows when cold, the second at operating temperature. The correct viscosity keeps the engine protected by an adequate oil film both on cold start-up and under full working heat. The value that applies to your car is set by its manufacturer.
Can different engine oils be mixed together?
It is not recommended unless unavoidable, because different additive packages can weaken one another. A small emergency top-up to correct the level does no harm, but the oil should then be fully replaced with a product of the correct class at the first opportunity.
What is the most important criterion when choosing oil?
Suitability, not brand: the manufacturer specification, the viscosity grade and compatibility with the engine's technology come first. At Alpay Servis the selection follows these criteria, so a quality oil of the correct class fully meets your engine's lubrication needs.
