Is 5w30 or 10w30 better for summer?

Answer: There is absolutely no need to switch to 10W-30 motor oil in the summer if 5W-30 is an acceptable grade for your engine. While some car manufacturers still advocate the use of 10W-30 (or even 10W-40) as an appropriate engine oil option for summer use, it is completely unnecessary.

Can I use 10w30 instead of 5W-30 in summer?

Although both 5w30 and 10w30 are multi-grade, the latter thins enough when living in an area with extremely low temperatures. This makes it perform much better during the winter season than 10w30. 10w30, on the other hand, will flow effectively in hot summers or higher temperatures.

Is 10w30 good for summer?

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.

Can I use 5W-30 in 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 35ºC, making it an ideal choice if you drive your car in a place with relatively high seasonal temperature variations.

Is 5W-30 better in summer?

Is 5w30 Or 10w30 Better For Summer? The 5w30 oil is a great multigrade oil that can be used in low starting temperatures and high summer temperatures. In addition, it is more fuel efficient since it reduces the drag on the bearings and engine parts, which reduces fuel consumption.

When should I use 10W-30?

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. Even though this multi grade engine oil can be used in a colder temperature, it's better suited for warmer weather.

What oil viscosity is best for hot weather?

A 30 grade oil, thick enough to protect in the heat, was recommended for summer use. Then, multi-grade oils were formulated. A 10W-30 had the winter cold start flow properties of a 10W and the summer, high-temperature thickness of a 30 grade.

What is 10W-30 oil recommended for?

10W-30 motor oil makes for a decent high-mileage oil. It gives a better fuel economy while reducing the oil consumption for older engines. Older engines with more than 75,000 miles on them require a thicker oil that will properly lubricate their critical engine parts and prevent oil leaks, sludge, and deposits.

What's the difference between 5W-30 and 10W-30?

Both the oils have similar viscosity at 100 degrees Celsius but 5w30 grade oil will thicken less than 10w30 grade oil in cold climate. This means 5w30 grade oil will flow effectively in low temperatures, whereas 10w30 oil will flow effectively in high temperatures because of the smaller temperature window.

Will it hurt my car if I use 10w30 instead of 5w30?

Synthetic oils will mix perfectly, as long as they have the same chemical composition. As a result, mixing 10w30 and 5w30 is not a problem since one will be topping up. It is not harmful to mix engine oils because 5w30 and 10w30 engine oils have close viscosity, so mixing them is not harmful.

Is 10W-30 thicker than 5W 30?

10w30 is more viscous than 5w30 and is also the thicker fuel amongst the two. This changes the efficiency of the two oils as well. 5w30 is less viscous and therefore can reach even the difficult parts of the engine for lubrication. But this is not possible with 10w30 since they are thicker.

When should I use 5W-30 oil?

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.

Can you mix 5W-30 and 10W 30?

It is still not a good idea to mix two different brands of oil, even if they have the same viscosity. The oil you use should be the grade recommended by your car manufacturer. However, if you mix two different brands of motor oil, you could damage your vehicle.

Should I use thicker oil in a high mileage 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.

Is 5w30 or 10w30 better for winter?

10w30, the thinner 5w30 will circulate quicker, and flow through bearing tolerances better during an engine startup in the winter or colder climates. The “w” behind the five and the 10 indicates that those are the viscosities in colder or winter temperatures.

What happens if you put 10w30 instead of 5w20?

Notwithstanding the recommendations of the car manufacturer, mixing 10w30 and 5w20 will not cause any sort of harm to the engine. However, a few drivers claim that it is safer to combine two multi-grade or straight weight oils, rather than mixing multi-grade with straight weight oils.

Should I use 5w30 or 10w40?

The 5w30 oil will flow better at low temperatures than the 10w40 oil. This means that the 5w30 oil will protect the engine better at low temperatures, usually when the engine is just starting or during weather conditions such as winter.

Will 10W40 hurt a 5w30 engine?

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.

Will thinner oils damage your engine?

Just like using an oil with too high a viscosity may lead to problems in Brad's engine, using a thinner oil can have the same result. Oil that's too thin can fail to develop a consistent lubricating film, inviting metal-to-metal contact that causes wear. Extreme stress and heat add to the challenge.
