Quick Answer Can I use 10w40 instead of 5W 20?

The Ranger said that you can mix 10W &amp
30W to get 20W, or you can mix 5W20 &amp
10W40, but you don’t want to mix 10W &amp
30W. The answer is yes, but not straight weights or multigrades.

Can I substitute 10W-40 for 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’s the difference between 5W and 10W-40?

The main difference between the two oil types is that one is thinner than the other. The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity).

What happens if you put the wrong viscosity oil?

If your motor oil’s viscosity is low, it can break down in extreme conditions, failing to lubricate your engine effectively. This creates excess heat and friction which reveals itself in a burned smell coming from the engine. With time and use, the damage will increase and engine parts will wear out prematurely.

What temperature is 10W40 good for?

10W-40 motor oil’s greater tolerance for hotter temperatures means that it’s better at resisting thermal breakdown and reducing deposit formation. So, if you drive in a warm climate — especially more than 32°C (90°F) — or have an engine that runs hotter than others, 10W-40 oil viscosity is a good option.

Can you mix 5w20 and 10W40 oil?

Yes. The best choice is always to avoid mixing motor oil brands, but different viscosity grades of the same brand can be used.

Is 10w40 better than 5w30?

5w30 oil is especially well suited to vehicles operating in cold climates. 5W-30 motor oil is mainly of cold-weather viscosity quality.Comparison Table Between 5w30 and 10w40.

Parameters of Comparison 5w30 10w40
Thickness 5w30 oil is thinner than 10w40 oil. 10w40 oil is thicker than 5w30 oil.

Can I use 10w 40 instead of 10w30?

The 10w30 and 10w40 oil options are both acceptable for your car, but if you have a high mileage car, you should use the 10w40 oil. Viscous 10w40 is more viscous than viscous 10w30. Older engines are able to handle higher temperatures and wear and tear more efficiently with thicker oil.

Does 10w30 hurt 5w30 engine?

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.

When should I use 5W-40?

5w40 is better for starting your engine at low temperatures as it flows more easily in this environment. When the engine is running and hot, the differences are negligible
5w40 and 10w40 both have high viscosities and are equally effective in protecting against engine wear.

Can you use 5W-40 instead of 10W-40?

If you need a 10w-40, you can use 5w-40. Both oils are equivalent at operating temperatures of 40Wt. The second number is the operating temp viscosity (the number that matters most). Colder oil viscosity is only affected by the first number (with a “w”).

What oil is thicker than 5W-40?

10W-40 is a bit thicker than 5W-40 but is still rather thin and works well to lubricate the moving parts of an engine during start-up.

What happens if you put 5W40 instead of 5w30?

The engine will not be improved by mixing different oils. When synthetic oil is mixed with regular engine oil, the additives may have little or no effect. If you mix 1 litre of 5W30 with 5W40, there will be no harm to the engine, as long as it is mixed with 5W40.

What oil is thicker than 5w30?

10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil.

Can I mix 5w30 with 10W40?

Is It Ok To Mix 10w40 With 5w30? The brand should be the same as the product. It is not compatible with the additives to mix brands.

Is 10W40 good for summer?

They are both available in pure conventional form or as high-quality synthetic grades. Either 10W30 or 10W40 for summer use is fine
however, 10W-40 motor oil will better protect your engine.

Is 10W40 good for high mileage?

Is 10w40 Good For High Mileage? The 10w30 and 10w40 oil options are both acceptable for your car, but if you have a high mileage car, you should use the 10w40 oil. Older engines are able to handle higher temperatures and wear and tear more efficiently with thicker oil.

What is the difference between 10W-40 and 20w 40?

Differences between 10W40 and 20W40

20w40 oils have a higher ‘W’ number, which means they will not perform well in colder temperatures, that is the only difference between the two oils.

Which is better 5w or 10W?

Super oversimplified answer: they are the same at operating temperature but the 5w is designed to flow at lower temperatures than the 10w. You can essentially interchange them because your owners manual will show you a chart with temperatures. If you live in a hot climate use 10w. I’m cold climates use 5w.

Can you put 10W30 oil in a 5w20 engine?

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.

Is 5w or 10W thicker?

A 10W or 5W is the index for how easily the oil flows in winter (hence the W). A 10W oil thickens more than a 5W. The other number indicates the oil’s resistance to thinning at high temperatures.

What is 10W-40 oil used for?

This oil weight is commonly used in diesel engines or in a smaller motorcycle engine too. The 10W-40 oil viscosity also often serves as an alternative for older engines with burning or oil leaking issues. Why is that? The 10W-40 engine oil has a thicker viscosity than, say, 10W-30 oil when the car engine is hot.

Is 10w40 oil thicker than 10W30?

The viscosity of hot oil is measured using different test parameters than when the oil is cold, so the numbers after the “W” don’t relate to the numbers in front of the “W”. The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature.

Is 10w40 better for older cars?

Is 10w40 Better For Older Cars? When you put more pressure on your vehicle’s engine at high temperatures, 10w40 will reduce wear and tear on the engine and make it more durable. 10w40 is also an excellent choice for older vehicles.

Is 10W30 better for high mileage?

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.

Is 10W30 good for winter?

Can I Use 10w30 In Winter? The 10W flow is good in cold weather, so it protects the engine at start up, but it is too thin for use in the summer when the engine is at full power. The recommended oil for summer use is a 30 grade oil that is thick enough to protect against 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.
