Everything you should know about motor oils :
You should follow the change interval as recommended in the owner’s manual. A good general rule is to change the oil every 5000 km, or every six (6) months whichever comes first.
metal components apart. The parts effectively ‘float’ on a thin film of oil which stops metal to metal contact reduces friction, heat and wear. The quality and performance of oil is a measure of its ability to perform these functions over a long period of time thereby increasing the reliability and performance of the engine components being lubricated.
Optimizing an oil’s viscosity, or thickness, helps maximize energy efficiency while avoiding component wear. Viscosity modifiers increase the viscosity of your oil at high temperature but have little effect on low-temperature viscosity. These enable your oil to flow properly when cold and also to remain
thick enough to protect your engine components at high temperatures.
Lower-viscosity grades of oil make it easier for your engine to start from cold because they present less resistance to moving parts and hence take less power from your engine. This also means that you get enhanced fuel economy.
- Detergents keep your engine clean and neutralize the corrosive acids that form as fuel is burned.
- Dispersants remove soot and sludge and hold it in the oil to prevent blockages. This dirt can then be removed from your engine at the next oil change.
- Anti-wear additives protect your engine by forming a chemical layer between the moving parts. These additives are particularly important when motoring with high loads or during engine start-up.
- Antioxidants help to delay the natural degradation of your motor oil, hence protecting your engine more effectively for longer.
- Friction modifiers reduce the drag between moving parts to increase fuel economy.
- Anti-rust additives are essential elements that prevent engine corrosion.
in an engine designed for the lower viscosity oil. Lower viscosity oil may help reduce internal engine friction because it takes less energy to pump the thinner oil throughout the small passages inside an engine. Any fuel mileage improvement associated with a Lubricants would be good for
them, and lighter viscosity grade motor oil will make a difference.
A thinner motor oil is also essential for easy starting, particularly in cold weather, and for proper lubrication once the engine starts. Thinner oils enable more fuel economy than thicker oils; this is why OEMs specify them. Thinner oils, such as SAE 5W-30, will flow faster than heavier motor oils during start-up and initial engine operation, and will help protect the engine. The viscosity grade(s) recommended by the vehicle manufacturer depends somewhat on engine design. Engine manufacturers have spent considerable time and expense experimenting with different viscosity grades and have indicated in the owner’s manual the grades they feel will best protect the engine at specific temperatures. While one manufacturer’s engine may require an SAE
10W-30, another manufacturer’s engine may require an SAE 5W-20 viscosity grade. This is likely due to different tolerances within the engine or other engine design factors.
that the motor oil is doing its job of keeping soot, dirt and other combustion contaminants in suspension to be carried to the filter or removed from the crankcase when the oil is changed.
Future Oil products have been formulated to hold these contaminants in suspension until they can be removed with an oil and filter change.
