Why is 5w30 oil so popular?

Why is 5w30 oil so common? 5w30 oil is one of the most commonly used motor oils because it is suitable for a wide variety of vehicles and engine types. 5w30's viscosity range means it can lubricate, seal, and protect an engine's internal components in a range of climate conditions.

What is 5w30 oil good for?

5W-30 oil is primarily a winter viscosity grade motor oil. While it does perform adequately at a higher temperature, its best use is for people who drive in cold temperature regions. Due to its lower viscosity, it's typically recommended for petrol vehicles or a light-duty diesel engine.

Why is 5w30 better than 5w20?

Ideally, 5W 30 oil is perfect for people who drive in seasonal or hotter climates. It has a better viscosity index than 5W-20 oil and is more versatile in terms of its warmer temperature range. You'll get better protection with 5W 30 oil in cold as well as hotter climates.

Is 5w30 any good?

Unlike oils with a higher hot temperature rating such as 10 or 15, 5w30 oil can flow freely enough when the engine is started at low temperatures to coat and protect the engine's internal components. It's also a good choice for long trips requiring greater fuel consumption and more exposure to heat.

Which is better 5w30 or 5w40?

5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.

Oil Explained! - What does 5W-30 actually mean?

Is 5w30 good for high mileage?

Amazon Basics Full Synthetic is the best 5w30 oil for high mileage vehicles. This oil should only be used on vehicles exceeding 75,000 miles. This motor oil is formulated for longer drain intervals. It helps in preventing a build-up on drain intervals and preventing rust and corrosion.

Is 5w30 good for summer?

When should I use 5w30 oil? You should always use the oil recommended by your vehicle's manufacturer. However, 5w30 oil can function in temperatures as low as -30ºC and as high as 40ºC, making it an ideal choice if you drive your car in a place with relatively high seasonal temperature variations.

Is 5W-30 full synthetic?

Keeps engines running like new

Mobil 1™ 5W-30 is an advanced full synthetic motor oil designed to keep your engine running like new by providing exceptional wear protection, cleaning power and overall performance.

Is 5w30 oil good for winter?

The Bottom Line. A multi-viscosity 5W30 oil flows quicker in cold weather and is recommended for year-round protection, and a synthetic 5W30 multi-viscosity will provide the best protection you can get in both extremely cold weather and extremely hot engine temperatures.

What does the W in 5w30 stand for?

The “W” stands for “winter,” the number preceding it indicates the oil's viscosity (or thickness) at low temperatures (hence the W), and the number after it indicates viscosity at higher temperatures, when the engine is running.

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

Myth: Once you switch to synthetic oil, you can never switch back. This is one of the most persistent myths about synthetic oil—and completely untrue. You can switch back and forth at any time. In fact, synthetic blends are simply a mixture of synthetic and conventional oils.

What happens if I put 5w30 instead of 5W20?

While both 5W20 and 5W30 motor oils are suitable for high mileage engines, the best viscosity type for your vehicle depends on how the manufacturer designed the engine. Using 5W30 when it is advised that you use 5W20 can result in your vehicle not getting good fuel economy.

Is it OK to mix 5W20 with 5w30?

Yes, you can mix 5W20 and 5W30 oil. However, your engine MUST support it. Both oils should be of the same brand to prevent engine damage and should also be of a similar API service level.

How long does 5W-30 oil last?

Mobil 1™ Extended Performance High Mileage 5W-30

Provides 20,000 miles of protection for vehicles with more than 75,000 miles – guaranteed.

Is 5w30 oil OK for car?

5w30 oil is particularly suitable for cars driving in cold climates. Unlike oils with a higher high temperature rating, such as 10 or 15, 5w30 oil can flow freely enough when the engine is started at low temperatures to coat and protect the engine's internal components.

Is it better to use 5w30 or 10w30?

Lubrication. 5w30 provides better lubrication compared to 10w30. It is best suited for private vehicles and light-duty diesel and petrol engines, while 10w30 is more suitable for commercial vehicles and other cars with heavy load engines.

What oil is best for summer driving?

As a general rule, you'll get the best protection in the summer when you use a slightly thicker grade of oil, such as a 10W30 instead of a 5W30. Engines need a thicker oil in the summer months because of the summer heat and its effects on thinning the oil out.

Is 5w30 an all season oil?

The 5W-30 is generally recommended because it is a good choice for use all year round. Changing to a lower viscosity oil for the winter may be recommended by your user manual if you are using a high viscosity oil.

Can I use 5w40 instead of 5w30?

In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.

What is the disadvantage of synthetic oil?

Probably the most glaring downside of synthetic oil is the cost. The price of synthetic oil is around two to four times the price of conventional oil. Synthetics may be more prone to additives precipitation during cold storage conditions.

Should I use thicker oil in an older engine?

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.

Can I use SAE 5W30 instead of 5W30?

Can I Use 5W-30 Instead Of SAE 30? Both oils have a “30” hot viscosity rating. This means SAE 5W-30 oil has the same flow rate as SAE 30 at operating temp. So, technically it's fine to use SAE 5W-30 oil in place of SAE 30.

What is the best 5 30 oil?

What is the best oil for a high mileage motor?

What type of oil is best for high mileage cars?

High mileage oil is designed for vehicles with more than 75,000 miles. Such oil features additives that help protect seals. This leads to less leakage and oil burn-off, which can be common in older cars. If your vehicle is high-mileage and high performance, it's suggested that you go with this type of synthetic oil.
