Which oil is thicker 5W or 10W?

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.

Should I use 5W or 10W oil?

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.

Can I use 10W instead of 5W oil?

A common question is whether it's safe to use 10W-30 instead of 5W-30 oil, for example. While it's best to use what's recommended in your owner's manual, inadvertently using a viscosity one grade higher or lower than what's recommended generally poses no long-term harm.

Is 10w40 thicker than 5W40?

10W40 Motor Oil Characteristics

Compared to 5W40, the 10W40 is thicker but a little bit thinner than average engine oils. This motor oil works perfectly well to lubricate all moving parts of your motorcycle's engine during start-up.

What if I use 10w30 instead of 5w30?

Can I use 10w30 instead of 5w30 in summer? If you were to use 10W-30 instead of 5W-30, the engine would be slightly less protected against wear during startup and colder temperatures. 10W-30 is also slightly less efficient at protecting your engine in extreme heat (above 140 degrees Fahrenheit).

Which Oil Is Thicker 5W 30 Or 10W 30?

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 is the 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.

Is 10W-40 too thick?

A low viscosity oil will move quicker through the engine to keep it lubricated and cool. Additionally, if your engine has a lower running temperature, 10W-40 motor oil might be too thick. Its higher viscosity at running temperature can reduce engine effectiveness as it'll need more energy to keep the engine operating.

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.

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.

Can I replace 5w30 with 10w40?

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.

Which oil is thicker 5w30 or 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.

What is the thickest engine oil?

Importance of a Viscosity Scale

In order to have a standard way to measure the viscosity of engine oil, the Society of Automotive Engineers (SAE) developed a viscosity scale. The scale ranges from 0W, which is the thinnest type of oil, to a rating of 60, which is the thickest oil.

Is 5W or 10W better for winter?

When it comes to 5W-20 or 5W-30 vs 10W-30, the opposite is true: the 5W oils will flow a little better in the cold than a 10W oil for maximum cold-weather protection and easier cold starts.

Is 5W or 10W 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.

What does 5W and 10W mean?

The lower the number, the thinner the oil and the better the oil's cold temperature/ cold start performance. The number after the W describes how thick the oil is at the engine's normal operating temperature.

Is thinner or thicker oil better?

Engine oil viscosity

Thin oils reduce friction in engines and help engines start quickly during cold weather. Thick oils are better at maintaining film strength and oil pressure at high temperatures and loads.

What oil is best for old engines?

What happens if I 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.

Can you use 10w40 instead of 5w40?

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.

What oil is thinner 5w30 or 10W30?

Both oils have lower viscosity at temperatures which measure the resistance of the oil to flow. However, 5w30 is much thinner compared to 10w30. 5w30 engine oils will, therefore, be able to protect the inner components of the engine faster than the 10w30 due to its low viscosity.

Is 5w30 or 10W30 better for winter?

Low Temperature Viscosity

Now, the lower the number before 'W' is, the less likely the motor oil will thicken at a low temperature. So when you compare 5W30 vs 10W30, 5W30 oil has a lower number (5), implying the oil thins fairly in an extremely low temperature, making it a better winter engine oil than 10W-30.

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.

Which is thicker 10/40 or 10w30 oil?

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.

Can I put 10w40 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.
