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 use 10w30 instead of 5w30 in winter?

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 OK for winter?

10W30 vs 10W40 Oil FAQs

10W-30 motor oil is recommended for ambient temperatures not exceeding -30°C/-22°F in the winter or 35°C/95°F in the summer. This is a great motor oil to use if you live in Canada or cooler U.S. states. Colder regions would require 5W-20, while hotter regions may call for 10W-40.

Should you run 5w30 in the winter?

An example is 5W30—the “W” stands for winter and the oil's cold weather rating. The lower the W number, the better the oil will perform in colder temperatures. Typically, a 5W oil is recommended for winter use, but synthetic oils can be formulated to flow even more easily when cold.

Is there a big difference between 5w30 and 10w30 oil?

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 Thinner Oils Damage Your Engine?

Which engine oil is best for high temperatures?

Mobil 1 advanced synthetic motor oil provides outstanding high-temperature performance and is proven to protect at engine temperatures up to 500 degrees Fahrenheit.

Which oil viscosity is better for warm climates?

A climate that experiences warmer temperatures all year long may necessitate a heavier engine oil such as an SAE XW-30 or XW-40 grade - one able to resist the breakdown that comes with higher operating temperatures by ensuring proper and adequate film thickness and the protection of critical engine components.

Is Thicker oil better in winter?

Thin oils have lower viscosity and pour more easily at low temperatures than thicker oils that have a higher 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.

Is synthetic oil better in cold weather?

Bottom Line: Synthetic motor oil is a much better choice when you're looking for a winter motor oil. It flows better for easier starts, smoother shifts and better protection against wear. Upgrade to synthetics to maximize cold-weather protection and performance.

Which oil is best for body in winter?

Can I use 10w30 instead of 5w30 Reddit?

It will be fine.

Is Thicker oil better for older engines?

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.

Will 5w30 hurt a 10w30 engine?

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.

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.

Does 10w30 hurt 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.

Does synthetic oil get thicker in cold weather?

Synthetic oil doesn't contain any wax, so it doesn't thicken up as much as conventional oil in the cold. In fact, synthetic oil doesn't contain any of the contaminants found in conventional oil, so it performs more consistently, even in extreme temperatures.

Do you need a block heater if you use synthetic oil?

You may not need a block heater if: Your car uses synthetic oil. Synthetic oil is made from artificial compounds and is used in extreme weather conditions. You park your car in a heated garage or in an area with really good, warm shelter.

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.

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.

What oil may do in freezing temperatures?

Oil doesn't really freeze when exposed to low temperatures, unlike other liquids. But their texture and consistency take on an almost solid form, making them incapable of flowing out of the container and inside the engines. This usually happens when the temperature reaches -20 degrees Fahrenheit.

What temp is 5w30 good for?

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.

What is 5W-30 motor oil used for?

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.

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.

Is 5W 30 better for hot weather?

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 40ºC, making it an ideal choice if you drive your car in a place with relatively high seasonal temperature variations.

What is the difference between 5W 30 and 10w 40?

5w30 motor oil is synthetic motor oil that has a viscosity of 5 in low temperatures and viscosity of 30 at higher temperatures, usually 100 degree Celsius. 10w40 motor oil is synthetic motor oil that has a viscosity of 10 in low temperatures and viscosity of 40 at higher temperatures, usually 100 degree Celsius.
