Is 5W-20 oil good for high mileage?

Designed for high mileage vehicles Mobil 1 High Mileage 5W-20 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils†), including: Cars. Trucks.

Do high mileage cars need thicker oil?

Identification. For an older, high-mileage passenger car, it is recommended to switch to a thicker viscosity oil, such as 10W-30, when approaching and passing 100,000 miles, to lubricate the engine well for preservation.

Should you use thicker oil in an older engine?

You should switch to thicker oil if your older car is consuming oil. The general rule is to always use the viscosity your car manufacturer recommended. As your engine gets older, the clearances within the engine change due to wear and tear, and your car could start to consume oil.

Can I use 5w30 instead of 5w20 in high mileage engine?

Can You Use 5w30 Instead Of 5w20. It is not recommended. Although they both have the same winter rating of 5, the thickness (viscosity) of 5w30 is a bit higher than 5w20. That means your engine’s at stake for using the high viscosity oil.

Is 5W-20 oil always synthetic?

SAE 0 oils are full-synthetic oils, whereas 5W20 might be partially synthetic or conventional. Even if your 0W20 and 5W20 variants are 100\% synthetic, the next thing you may need to worry about is warranty and fuel consumption.

When should I use 5W-20 oil?

5W-20 oil is best for those who live in colder climates with low temperatures. It can be used for light-duty applications, for engines that do not reach very extreme temperatures. 5W-20 oil provides excellent start-up performance in colder temperatures.

Is 5W30 good for high mileage?

5W-30 motor oil is the top viscosity recommendation by automakers over the past four decades for use in many vehicle types. Furthermore, high-mileage 5W-30 motor oil is specially formulated for late model vehicles or newer vehicles with over 75,000 miles/120,000 kilometers.

Is 5W30 thicker than 5w20?

A. When it comes to their higher operating temperature performance, 5W30 motor oil performs slightly better than 5W-20 and is a thicker oil than its counterpart. 5W30 motor oil would be more robust and not break down very easily at a higher temperature.

Which oil is better 5W20 or 5W30?

5W-30 Versus 5W-20 5W-30 and 5W-20 motor oil both feature the same winter rating. However, 5W-30 features a slightly higher viscosity at 100 degrees Celsius than does 5W-20. This means that once the engine reaches normal operating temperature, 5W-30 oil will be thicker than 5W-20.

Which is heavier 5W20 or 5W30?

So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures.

How long does 5W-20 oil last?

Protects for up to 20,000 miles between oil changes* Mobil 1 Extended Performance 5W-20 advanced full synthetic motor oil is designed to deliver outstanding engine protection and protect critical engine parts for up to 20,000 miles between oil changes.

What happens if I put 5W-30 oil in my car instead of 5W20?

Your vehicle’s engine is built and tuned to run on a specific grade of oil. If you put in 5W-30 oil instead of 5W-20 when the latter is the grade suggested by your vehicle’s manufacturer, damage to internal engine parts can occur. Additionally, your engine may experience performance issues such as diminished fuel economy and horsepower.

What is the difference between 5W20 and 0W20 engine fluid?

A 0W20 will be more fluid than a 5W20 at startup temperatures but will perform the same way at standard engine operating temperatures. Remember, engine oils naturally thicken as they cool down and thin as they are heated.

What is the difference between Sasae 0 and 5W20 oil?

SAE 0 oils are full-synthetic oils, whereas 5W20 might be partially synthetic or conventional. Even if your 0W20 and 5W20 variants are 100\% synthetic, the next thing you may need to worry about is warranty and fuel consumption.

Can you use 5W20 instead of 0W20 in Florida?

You cannot use either 0W20 or 5W20 in areas where temperatures exceed 20°C/68°F like Florida. Viscosity. The smaller the number, the better the motor oil will flow. A 0W20 will be more fluid than a 5W20 at startup temperatures but will perform the same way at standard engine operating temperatures.
