What is 5w30 oil used 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.

When should I use 5W-30 oil?

5w30 oil is particularly well suited for cars driven in cold climates. 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.

What cars can use 5w30 oil?

The '30' or '40' refers to the oil flow at higher engine temperatures. '30' is often for newer petrol engines, while '40' is often for older or diesel engines. 5W-30 and 5W-40 oils are compatible with some models of common cars, like the Ford Focus, Ford Ka, Honda Civic and VW Golf.

Can 5w30 be used in any car?

Why is 5w30 oil so versatile? The car engine oil can be used in a variety of engine types and under a wide range of temperatures. Also, it can be used in your car or SUV, irrespective of whether it is petrol-powered or diesel-driven.

Is 5w30 good for hot weather?

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.

Castrol 5W-30 oil explained | Which oil for my car? | Castrol U.K.

What does 5W-30 mean?

Example 5W30: The W stands for winter, whereby 5W is the low temperature viscosity and 30 is the high temperature viscosity at 100 degrees Celsius. The lower the number before the W, the better the oil will flow at low temperatures.

What's better 5W-30 or 10W-30?

Suitable Vehicle Types. 5W-30 multi grade oil is ideal for private vehicles and light-duty petrol and diesel engines. It also provides a better cold temperature start than 10W-30 oil. On the other hand, the slightly thicker oil,10W-30, provides better lubrication for commercial vehicles and heavy-load engine cars.

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.

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 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.

What happens if you put the wrong oil in your car?

Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.

What happens if I put 10w40 instead of 5w30?

Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

What happens if you put 5w30 instead of 5w20?

If you use 5w30 oil instead of 5w20 when it is not recommended or approved by your owner's manual, it can void your car's powertrain warranty, reduce engine efficiency, and possibly even damage your engine in the long run. Hopefully, this helps!

Is 5W30 better for older cars?

5W-20 and 5W30 motor oil are winter viscosity grade oils primarily recommended for older engines and light-duty use. These oils are best utilized in colder temperatures.

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.

Which oil 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.

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.

Which oil is best for cold weather?

So, a 5W-30 or 0-W30 will give better protection in winter weather than, say, a 10W-40 or a 20W-50, while still providing solid high-temperature protection. You should also consider asking for a synthetic or synthetic blend motor oil.

What happens if you put 5w30 instead of 10w30?

So both the oils 5W–30 and 10W–30 have exactly the same viscosity (SAE 30) when your engine is running, and will perform in the same way. However, the 10W–30 oil will be thicker (higher viscosity) than the 5W–30 when it is cool.

Can I switch from 10w30 to 5w30?

Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.

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.

What happens if 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.

Are all 5w30 oils the same?

As a result, every engine needs its own specific package of additives. And that's why there are so many 5W30 oils, each with a different composition and OEM (Original Equipment Manufacturer)-specification. This means we can honestly say that a “universal” or one-fits-all 5W30 lubricant does not exist.

Is 5w30 oil for petrol or diesel?

5w30 is a motor oil widely used in light petrol and diesel engines. Like most motor oils produced today, 5w30 is a multi-grade oil, meaning it ranges from a lower viscosity grade of 5 to a higher viscosity grade of 30.
