What are the differences between synthetic oils and lubricants?
- Lubricants are generated by distilling and refining petroleum. Synthetic oils are oils that have been adapted to the desired properties by chemical synthesis.
Which oil should be used in a vehicle with DPF?
- Improving a single parameter after adding an additive does not mean that the oil will have better performance.
- Delicate balances in additive proportions in the formulation are upset.
- Using a different formulation than the OEM approved oil in the engine leads to the risk of the vehicle being out of warranty.
- Disruption of the original formulation of the oil due to the addition of an external additive, or any problems occurring in the vehicle fall outside of the oil manufacturer's warranty.
- Therefore, no additives should be added.
*In vehicles with DPF, using an incompatible engine oil causes clogging in the diesel particulate filter. Therefore, the right oil should be chosen for DPF.
*Can external additives be added to engine oil?
In today's engine oil technology, there is no need to add any external additives for performance.
Does thick oil ensure better engine protection?
- Oils contain detergent and dispersing additives. These additives keep the engine clean and help impurities adhere in oil,
- thus darkening the oil color.
- What matters is the amount of impurities in the oil. If it is too much, it can damage the engine. Therefore, the cleaning performance of the oil filter is critical.
- The oil to be added should be of the same viscosity class and at the same performance level.
- Synthetic oils should not be mixed with a lubricant. This may disrupt the chemical structure of the oil without directly and immediately damaging the engine.
In fact, engine oil recommended by the equipment manufacturer ensures better protection.
In addition, the viscosity of engine oil is not the only parameter for operation and protection performance. It is essential that the oil film ensures protection without being disrupted at the operating temperature of the engine.
What does it mean if the color of the engine oil gets darker?
If the color of the engine oil gets darker, it indicates that the oil is operating at the correct performance.
Another mistake is adding different brands of oil to the vehicle. It is generally not recommended to mix different brands of engine oils with each other unless absolutely necessary. This may cause chemical changes in the oil in the engine due to the presence of different additives. It can be applied provided that the oil is fully renewed after a short time.
What is the shelf life of an engine oil?
- The vehicle manufacturer and authorized services determine the oil change periods in vehicles.
- Change intervals are determined based on the information obtained by equipment manufacturers in the laboratory and as a result of field tests.
- The lubricant manufacturer should document their statements, if any, regarding the oil service life and/or change interval.
How can you tell that an engine oil has expired?
- Complex chemical/physical tests are necessary to understand whether the oil has expired or not.
- Such tests can only be performed by advanced laboratories.
What does 5W mean?
- 5W is the viscosity value of engine oil. The letter W stands for the word winter. The number 5 on the left indicates the cold working condition of the engine oil.
Why do we need to use antifreeze?
- To prevent water from freezing,
- prevent calcification,
- protect the system against corrosion and
- increase the boiling point.
Antifreeze protects the engine cooling system. Functions of antifreeze:
What are the application areas of grease?
- Grease is used in particular to lubricate rolling bearings. Different types of greases are used in a number of industries.
What are greases made of?
- The structure of a grease consists of three critical substances. These are base oils, thickeners (soap types) and additives.
How is viscosity classified in hydraulic oils?
- In hydraulic oils, viscosity is classified based on ISO VG class.
