Engine Oils
As a general principle, mixing of oils with different properties and different brands is not appropriate. However, the decrease in oil was a variety of reasons and if it is necessary to complete the same viscosity and quality class can be added with other brand oils. It is recommended that the oil is completely drained and replaced with new oil at the most convenient time after the addition with another brand of oil. Hydraulic brake fluid at the same quality level can be mixed with each other regardless of brand.
To understand for certain whether motor oil has perished, the oil should be analyzed physically and chemically under laboratory conditions.
Synthetic oils are produced through very complex processes with advanced technology, it costs higher than mineral oils. That influences the price of the product.
Gear Oils
It is the API classification used for gear oils. Oil that contains additives to balance excessive pressure and pulsed load for hypoid gear type differentials running under heavy conditions and that fulfills MIL-L-2105 specifications. In GL-5, there are more overpressure additives and it is generally used under heavy work conditions. Unless otherwise specified, GL-5 should not be used in places where GL-4 is recommended. Because the sulphide in overpressure additive which is present excessively in GL-5 corrodes yellow metals.
Synthetic based oils are oils produced with chemical methods. They are produced to lubricate in applications where traditionally obtained mineral oils cannot be sufficient. Synthetic-based oils provide superior protection at higher temperatures than minerals, easier flow and pumpability at low temperatures , more stable film strength under extreme pressure and longer drain interval in difficult operating conditions.
The Association of Automotive Engineers (SAE) classifies automotive gear oils according to their kinematic viscosity values ​​at 100 °C and their pumpability at low temperatures. For example, the SAE 80W-90 in an automotive gear oil '90' describes the kinematic viscosity of this gear oil at 100 °C. As this number increases oil thickens, if the number decreases oil thins. The kinematic viscosity of '90' gear oil at 100 °C is between 13.50 and 18.50 cST while the kinematic viscosity of '140' gear oil at 100 °C must be between 24.00 and 32.50 cST. The number to the left of W (Winter) determines the performance of gear oil at low temperatures. Pumping temperature of '80W' gear oil is -26 °C while pumping temperature of '75W' gear oil is -40 °C.
Engine Oils
In many respects, synthetic oils have superior properties than mineral oils. Long life is one of them. Compared to mineral oils, synthetic oils as a general principle it can be said to have the better extended oil drain intervals. However, the oil change intervals are determined by the vehicle manufacturers (OEMs) after a series of tests. Compliance with these oil change intervals is the best in terms of equipment health.
The information on the oil packaging contains important clues about performance of the oil. There should be information about five issues on the packaging in general. These; brand, its contents (be mineral, synthetic or synthetic based), viscosity grade (such as 5W-30, 10W-40), international performances (such as API CK-4, ACEA C3), OEM performances (such as MB-Approval 228.51, Volvo VDS- 4, VW 504 00/507 00).
Vehicle should be in 'stop' position and on a flat surface. The engine oil must be drained when hot. Ensure that the old oil in the engine crankcase fully discharged, whether used oil in engine pan is empty and whether pan bung is mounted properly.
With manual hand pump or air pump can be printed directly into the bearing. In systems with central automatic lubrication, the grease is filled into the central chamber, the pneumatic system greases the greasing points automatically with the specified intervals.
Greases may leak during storage and base oil also tends to oscillate. The oil leakage rate will increase over time and will vary depending on the storage temperature. The grease should ideally be stored in a cool, dry interior and the ambient temperature should not exceed 30 °C and should not be less than 0 °C. The grease must be protected from dust, dirt, moisture or rainwater, and from direct sunlight.
In terms of application of lubricating with oil where it is not possible to use grease especially in ball bearings.
