What grade of oil should you use?

Say your engine needs 30-weight oil when it is running at operating temperature. Well, 30-weight oil will work perfectly well when your engine is warmed up. But when you go to start it on a cold winter morning, that 30-weight oil is considerably thicker and has a hard time moving when you turn the key.

What grade of engine oil should I use?

A lower number is better before the W for cold-weather performance, so a 5W oil is typically what's recommended for winter use. However, synthetic oils can be formulated to flow even more easily when cold, so they are able to pass tests that meet the 0W rating.

Which engine oil grades are more preferred?

0W40: It is considered the most superior in the Indian market. Its efficient performance in both hot and cold climate with the least sludge. It makes it ideal for modern-day petrol and diesel-driven cars.

Which oil is better 5w30 or 10w40?

The first number in the motor oil's name describes the oil's cold viscosity. ... A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine's moving parts more than the lower viscosity 5w-30 oil.

Does the grade of oil matter?

So even if your bike and your car both use 5W-30 oil, they're not interchangeable. On the subject of changing oil grades, though, the answer is, “It depends.” In situations involving extreme temperature and wear, some manufacturers do have alternative oil grade recommendations.

When should I use 20w50 oil?

20W-50 is a common motor oil used in moderate-to-large diesel and gasoline engines, high-performance motorcycle bikes, and aviation vehicles. Its resistance to thinning at high heat also makes it popular as a racing oil and high temperature driving.

What does 10W30 mean?

That's why you see two numbers on most oils. For Example: 10W30. This means the viscosity is at 10W when the engine is cold and 30 when the engine is hot. Low viscosities are good for cold temperatures (hence the “W” association) because the oil is thinner. Thinner motor oil flows more easily and moves quickly.

Can I change my engine oil grade?

MYTH: Changing your vehicle's motor oil yourself or using a certain brand voids your manufacturer's warranty. ... As long as the motor oil being used meets the manufacturer's standards required for the vehicle (e.g., viscosity grade, type), as provided in the owner's manual the warranty cannot be considered void.

Can I use 15W40 instead of 5w30?

5w30 flows better than 15w40. 5w30 provides best cold start properties. Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine's crank. No, you won't blow a head gasket, but 15W40 is too heavy an oil to use where 5W30 is required.

When should I use 15W40 oil?

ADVANTAGE 15W-40 HEAVY DUTY DIESEL ENGINE OIL can be used with complete success in over-the-road diesel trucks, off-highway diesel equipment, farm tractors, and passenger cars and light trucks with diesel, turbo-charged diesel engines, or gasoline engines and is backward compatible with previous API Oil Categories.

What happens if I put 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.

When should I use 10W40 oil?

While both are low-temperature grade oils, 10W40 is thicker at high temperature; therefore, better to use in warm weather.

Does 10W40 hurt 10W30 engine?

If you were to put 10W40 in an engine designed for 10W30, the “thicker” oil would lead to friction in the engine and an increased load on the oil pump. The car would have to do more work to get the oil around the engine block.

Which oil is thicker 5w30 or 10w30?

10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.

Will thicker oil damage my engine?

Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.

Does a car run better with new oil?

Changing your oil offers a lot of noticeable benefits, as well. Regular oil changes improve your car's gas mileage. As the fresh oil moves through the engine, the lubrication of the metal parts increases your engine's performance and helps it run more efficiently with less work so it doesn't eat up as much gas.
