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.

Is there much difference between 5w30 and 10w40?

The main difference between 5w30 and 10w40 is that the viscose of 5w30 is five at low temperatures, whereas the viscose of 10w40 is ten at low temperatures. 5w30, as well as 10w40, are both suitable depending on the layout of your engine and the heat in your area.

Can I use 10W instead of 5w30?

The answer is yes. You can use 10w30 instead of 5w30 oil since both meet the SAE standard for viscosity at operating temperature. Generally, the viscosity difference between the two is neglectable.

What happens if you put 10W oil in a 5W engine?

There is a small benefit of using a 10W instead of a 5W oil in that the 10W will normally have less viscosity improvers in it. Viscosity improvers help the oil behave "thicker" at higher temperatures, but they do not actually provide lubrication.

What happens if you put 10W-40 instead of 5W 40?

Can I Use 10w40 Instead Of 5w40? The synthetic engine will be fine as long as it is fully synthetic. 5W – 40 is better for colder conditions, 10W is thicker to start, so it does not get to places around the engine as quickly as 5W-40, but it all depends on the temperature.

Speed test | 5w30 vs 10w40

Is 10W-40 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. This oil's number "40" means it will be a little thicker than average while exposed to the heat of a running engine.

Is 10W40 good for winter?

Is 10W40 good for winter? Generally, the answer to this is yes, since it is a low-temperature oil grade.

Can I use 10W instead of 5W?

According to API motor oil guide [1], If you are using 10W–30, you can safely switch to 5W–30 (in car engines). 5W–30 is thinner than 10W–30 when cold. (you must follow the manufacturer's recommendations). However, switching from 5W–30 to economical 10W–30 is not always recommended.

Does 5W or 10W matter?

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 happens if you put 10w30 instead of 5W 30?

Both 5w30 and 10w30 engine oils have a similar SAE rating, meaning that they will perform the same at high or operating temperatures. The digits 30 indicates the viscosity of the oils when in high temperatures. 10w30, however, will thicken more when in a cold climate. 5w30 is much suitable during the cold season.

Will 10W-30 oil hurt a 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.

Is 10W-30 the same as 5W 30?

The main difference between 5w30 and 10w30 is that 5w30 is less viscous and more efficient than 10w30 because the fuel is thinner and can reach the difficult part of the engine. 5w30 is a viscosity engine oil that is used for engine lubrication.

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

You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn't working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.

Can I mix 10W40 with 5w30?

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 10W-40 OK for my car?

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 is the difference between 10W-40 and 5W 40 engine oil?

5W40 vs 10W40 – Differences

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 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.

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.

Can 10W40 be used instead of 5W20?

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

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.

Can I use 10W30 instead of 5W30 Reddit?

It will be fine.

What temperature is 10W40 oil good for?

However, 10W-40 engine oil is more viscous in hotter climates and has a better temperature spectrum. Here's the recommended ambient temperature range for each oil grade, in general: SAE 10W-30 motor oil: -25°C (-13°F) to 30°C (86°F) SAE 10W-40 motor oil: -25°C (-13°F) to 40°C (104°F)

Is 10W40 fully synthetic?

Semi-synthetic oils such as 10W40 have long been the standard. Their base is refined crude oil, which is then blended with additives. However the market is moving towards synthetic oils.

Which oil is better 10W30 or 10W40?

The higher this number is, the more protection the oil provides when dealing with extreme heat and pressure. With this in mind, the only difference between 10W30 and 10W40 oil is the viscosity during higher temperatures and more pressure. 10W40 is going to be thicker when the temperatures rise.
