Which oil is thicker 10w40 or 20w50?

10w40 oil is a popular all-purpose oil designed in many different engines. 20w50 (also known as 10w30) is another popular all-purpose oil used in engines. The differences between 10w40 and 20w50 are small, but they have something in common: They are thicker than regular 20w50 oil.

What is the difference between 10W 40 and 20W-50 oil?

The motor oil will behave differently in hot weather if the temperature is cold rather than high temperature. At low temperatures, the motor oil will thicken resulting in improper lubrication. Therefore the 20w50 viscosity is made for high-temperature situations and the 10w40 is for cold temperature situations.

Is 20W-50 thick oil?

SAE 20W-50 is a thicker oil with high viscosity at hot temperatures and is highly resistant to oil thinning. Despite being one of the less popular oil viscosity grades, it's still recommended for a lot of automobile vehicles.

What oil is thicker than 10w40?

The higher the number, the more viscous or thicker, the oil is at higher temperatures. This means that at 100^oC, 10W30 engine oil has the viscosity of an SAE 30 single grade oil, and 10W40 oil has SAE 40 viscosity.

What is 20w50 motor oil used for?

A SAE 20W-50 motor oil is typically used in older vehicles or in particularly warm climates. Castrol GTX 20W-50 has been specially formulated to help extend the life of your engine by keeping it free from sludge, even when operating in extremely high temperatures.

R

Which motor oil is the thickest?

Importance of a Viscosity Scale

In order to have a standard way to measure the viscosity of engine oil, the Society of Automotive Engineers (SAE) developed a viscosity scale. The scale ranges from 0W, which is the thinnest type of oil, to a rating of 60, which is the thickest oil.

Which is better 20W 40 or 20W 50?

20W40 is suitable for hotter climates and will not cause sludge as opposed to 20w50 which is more appropriate for hotter conditions.

Is Thicker oil better for older engines?

A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil - 10W - can help protect worn engine bearings as well.

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.

What is 20W 40 oil used for?

20W40, similar to other motor oil with different grading, is used for engine lubrication, protection against rust and corrosion, and keeping the engine clean.

What is 10W-40 oil used for?

Higher viscosity oil such as a 10W-40 can be useful for older engines burning or leaking oil. We offer Mobil™ 10W-40 high viscosity motor oils for use in vehicles with more than 75,000 miles, and a synthetic blend oil when cost is a consideration.

Is 20w50 good for petrol engine?

Suitable Vehicles

Depending on the recommendations for the particular vehicle, 20W50 oil is suitable for large or small diesel engines, gasoline engines, motorcycles and aviation vehicles. It is also suitable for both air- and liquid-cooled engines.

Which is better 10w30 or 20w50?

It really comes down to personal preference. As your engine does put out significant horsepower, we would lean toward using 20W-50. If your engine sees very light duty or is built exceptionally tight, 10W-30 would be fine. But again, if you twisted our arm, we would give 20W-50 the nod for the thicker viscosity.

Which is thicker 15w40 or 20w50?

The higher the number the thicker the oil so in this case 15w40 oil will be a thinner oil. When you say which is better it depends on what the oil is for if it is for a car engine a oil which is 30 or 40 will better to use than a 50.

What oil can I use instead of 20w50?

Re: Substitute For 20W-50 engine oil? 5w50, 15w50 and 10w60 tend to be the alternatives.

Which is better 10w50 or 20w50?

10w50 is thinner than 20w50 at low temp. So it will flow between every small parts and gives better cold start as compared to 20w50. First number lower than recommended and second number higher than recommended is good. You can go for 10w50.

What is 10W 50 oil used for?

10W50 oil is a high-performance engine oil that offers outstanding engine reliability and temperature stability under extreme driving conditions. It's used for a wide range of motorsports and modern engines with turbochargers.

What does 10W-40 stand for?

10W-40 10W-40 is the engine oil which offers a 10 weight performance in the cold starting temperature. On the other hand, it provides a 40 weight performance at the normal operating temperature of the engine.

Is 10W40 good for high mileage?

Designed for high mileage vehicles

Mobil 1 High Mileage 10W-40 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils^†), including: Cars. Trucks.

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.

What happens if I put thicker oil in my engine?

Thicker Oil May Not Flow Quickly Enough

Its lower viscosity allows it to flow faster and fill the tiny clearances between parts, leading to a durable, consistent lubricating film. Not only that, but the engine will waste energy pumping the thicker oil, reducing fuel economy.

Which oil is best for old engines?

What is the difference between 40 and 50 oil?

Introduction of SAE 40 & SAE 50 Diesel Engine Oil

In layman's term, we can say 40 is the thickness of the oil. More is the thickness, lesser is the contact between metals, which expands the life of engine motor. SAE 50. MOTOREX HEAVY DUTY SAE 50 is an alloy basis, mineral-oil-basis monograde engine oil.

Can I use 10w40 instead of 20W40?

10w-40 can give better performance in replace of 20w -40 oil. In a 10w-40 for example the 10w bit (W = winter, not weight or watt or anything else for that matter) simply means that the oil must have a certain maximum viscosity/flow at low temperature.

What happens if I use 20W50 instead of 20W40?

20W50 will hold on to the viscosity marginally better than 20W40 when the engine gets hot. However, 20W50 mineral oil will cause more sludge than a similar 20W40 because 20W50 will have more viscosity improvers. Pulsar 150's manual recommends 20W40, but you can use either, not much of a difference.
