Which oil is better 5w30 or 10w30?

5W-30 multi grade oil is ideal for private vehicles and light-duty petrol and diesel engines. It also provides a better cold temperature start than 10W-30 oil. On the other hand, the slightly thicker oil,10W-30, provides better lubrication for commercial vehicles and heavy-load engine cars.

What is 10W 30 oil recommended for?

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 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.

Which Oil Is Better 5W30 Or 10W30?



Can I switch from 5w30 to 10w30?

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 5w30 thicker than 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.

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.

Is 10W30 good for summer?

As a general rule, you'll get the best protection in the summer when you use a slightly thicker grade of oil, such as a 10W30 instead of a 5W30. Engines need a thicker oil in the summer months because of the summer heat and its effects on thinning the oil out.

Is 5W better than 10W?

A quick lesson in motor oil states that a regular engine needs oil that flows under the prevailing weather or running conditions. 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.

Is 5w30 good for 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 10W30 good 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.

Can I use 5w30 in hot weather?

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 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.

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 does 10W 30 stand for?

The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold, and 30 when the engine is hot. This is different than an oil labelled 5W30, which has a thinner viscosity when the engine is cold at 5W.
