Does it matter if I use 10W40 instead of 5W-30?

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 when you mix 5W-30 and 10W40?

From Shell.ca: “If you mix viscosity grades such as a 5W30 low-viscosity oil and a 10W40 higher-viscosity oil, it is reasonable to expect that the resulting product will have viscosity characteristics which are thicker than the 5W30, but thinner than the 10W40.

Is 5W-30 or 5W 40 better for winter?

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.

Is 5W or 10W oil better?

Absolutely yes for car engines, 5W-30 is usually synthetic and superior to 10W-30. Both have the same viscosity at the operating temperature of an average car engine. 5W has lower viscosity when cool and is considered better for the car engine during engine start.

Can you mix 10W40 and 5w30 oil?

Yes, there is nothing to prevent you from mixing engine oils of differing viscosities. The result will be a viscosity somewhere between that of the two blended oils dependent on the mix ratio. Originally Answered: Is it okay to mix 10W30 oil with 10W40 oil?

Which oil is thicker 5w30 or 10W40?

A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

What’s the difference between 5w30 and 10W40?

Is 5w30 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.

Is 10W40 better than 5w30?

The first number in the motor oil’s name describes the oil’s cold viscosity. A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

What is 10W40 oil used for?

Higher viscosity oil such as a 10W-40 can be useful for older engines burning or leaking oil. We offer Mobil™ 10W-40 high viscosity motor oils for use in vehicles with more than 75,000 miles, and a synthetic blend oil when cost is a consideration.

What is the difference between 5W30 oil and 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. At high temperatures, the 5w30 oil is thinner than that of 10w40 since 30 is lower than 40. These numbers, however, do not depict the actual viscosities of…

When to use 5W motor oil?

It is recommended that you keep 5W motor oil on hand before the first gust of cold strikes. 5W viscosity grade calls for the lubricant to properly flow at lower temperatures as compared to, for instance, oil with 20W viscosity, hence you should use it when the weather is cold.

What type of oil should I use for my motor oil?

Thinner motor oil flows more smoothly and quickly when the engine is cold, which is why you should not use anything less than 5W-30 in the summer. There is no dearth of motor oils that deliver high performance and withstand extreme temperatures, dirty climates, and aggressive driving.

What kind of cars use 5W-30?

Modern cars, for instance, turbocharged and a gasoline engine and diesel engines of cars, SUVs, light vans and trucks. 5W-30 can be purchased as conventional, synthetic, or blend
