What does 20w50 mean?
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.When should I use 20w50 oil?
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.Is 20w50 better than 10w40?
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.Which is better 20w50 or 10w30?
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.What is the difference between 5w30 and 20w50?
20w50 is actually thicker than 5w30. This will result in less fuel efficiency, less horsepower, and more engine damage because it will have to work harder to rotate.What Is The Meaning Of Engine Oil Grades Like 20w50, 10W40, 5w20 | Which One We Should Use?
Will 20W 50 hurt my engine?
If you use 20W-50 oil in an engine that requires 5W-30, for example, you won't notice any immediate engine damage. But your vehicle will experience engine wear each time you start your engine at a low temperature.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.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 oil can I use instead of 20w50?
Re: Substitute For 20W-50 engine oil? 5w50, 15w50 and 10w60 tend to be the alternatives.What is the thickest grade of motor oil?
Importance of a Viscosity ScaleIn 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.
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.Which engine 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.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 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.What is 20W 20 oil used for?
MOTOR OIL EXTRA SAE 20W/20 is suitable for vehicles, motorbikes and stationary systems that are operated with monograde motor oils. EXTRA monograde oils can also be used in specific gears and hydraulic systems for which monograde motor oils are required.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.Can I use SAE 30 instead of 20w50?
As I was getting at in the above section, no, SAE 30 is not the same as 20w50. They are actually very different types of motor oil. The biggest difference is that SAE 30 is only rated for its viscosity one time while hot. This is because SAE 30 is only intended for use in engines that don't need to start in the cold.Which engine oil is best for old engines?
When you're choosing the best oil for older cars or high mileage engines, there are several criteria you can look at.
- Pennzoil High Mileage Conventional Motor Oil. ...

- Valvoline MaxLife High Mileage Synthetic Blend. ...
- Mobil1 High Mileage Engine Oil. ...
- Amsoil Premium Protection Motor Oil.
What oil is better for older cars?
Monograde oils are still widely available, primarily because they're used in very hot climates, or in heavy-duty applications such as mining or construction equipment. These single-grade oils can be used in 1950s and older cars – generally SAE 30 to SAE 50 – but most owners use multi-grade.What's the best oil for high mileage engines?

Will synthetic oil hurt older engines?
It protects better, performs better, and lasts longer, and it's no longer made with a chemical compound that could hurt older vehicles. Modern synthetic oil is safe to use in all types of vehicles, ranging from new purchases to classics to aging not-so-classics.Will the wrong oil damage my engine?
Cause damage to engine lifeThe wrong engine oil can cause engine damage because it does not properly lubricate its components. This will lead to metal-on-metal contact since the moving parts are not being lubricated. Friction quickly follows, causing engine parts to wear.
Is thinner or thicker oil better?
Engine oil viscosityThin oils reduce friction in engines and help engines start quickly during cold weather. Thick oils are better at maintaining film strength and oil pressure at high temperatures and loads.
