What is the difference between different types of engine oil?

The “w” in motor oil stands for winter. … For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. The higher number, following the “w” refers to hot weather viscosity, or how fluid your oil is at hot temperatures. The higher the number, the thicker the oil at a specified temperature.

Does engine oil Quality Matter?

Does brand matter? As long as the grade and ACEA specification is correct, you should be fine. However, David Wright of the United Kingdom Lubricant Association recommends choosing reputable manufacturers. … Badly lubricated parts will wear faster and so decrease the life of the engine.

What happens if I use 10w40 instead of 5w30?

If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

Why do different engines use different oil?

The reason for this is that engines often need a different viscosity based on operating conditions. Knowing how scientists see viscosity will help an owner determine the best oil for the engine. Viscosity, at its most basic, is a fluid’s resistance to flow.

Why can’t you go back to regular oil after synthetic?

Switching to synthetic oil causes leaks: Generally, switching to synthetic oil does not cause leaks. It is true that synthetic oil is thinner than conventional oil and therefore flows more easily. … You can’t switch back to conventional oil: Once you switch to synthetic, you are not bound to it forever.

Which is better conventional or synthetic oil?

Synthetic oil has molecules that are equal size. More uniform oil molecules equals better lubrication, and that equals better engine performance. Synthetic oil stays slippery at colder temperatures than regular oil, and is therefore less likely to cause engine problems when started in cold climates.
