What motor oil is better for cold weather?

So, a 5W-30 or 0-W30 will give better protection in winter weather than, say, a 10W-40 or a 20W-50, while still providing solid high-temperature protection. You should also consider asking for a synthetic or synthetic blend motor oil.

Is 5W-30 or 10w30 better for winter?

10w30, the thinner 5w30 will circulate quicker, and flow through bearing tolerances better during an engine startup in the winter or colder climates. The “w” behind the five and the 10 indicates that those are the viscosities in colder or winter temperatures.

What engine oil is best for cold weather?

When it comes to cold weather, these top oils are the best for your vehicle

  • Mobil 1 Synthetic Motor Oil. …
  • Castrol GTX MAGNATEC 5W-30 Full Synthetic Motor Oil. …
  • Valvoline Advanced Full Synthetic SAE 5W-30 Motor Oil.

Is 5w20 or 5W-30 better for winter?

You’ll get better protection with 5W 30 oil in cold as well as hotter climates. 5W-20 oil is best for those who live in colder climates with low temperatures. It can be used for light-duty applications, for engines that do not reach very extreme temperatures.

Is synthetic oil better for cold weather?

The Bottom Line: Synthetic motor oil and drivetrain lubricants perform better in the cold than conventional oils. They flow better for easier starts, smoother shifts and better protection against wear. Upgrade to synthetics to maximize cold-weather protection and performance.

What happens if you put 10w30 instead of 5w30?

Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.

What happens if you use 10W40 instead of 5w30?

If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

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.

Should I use 10W30 or 10W40?

The higher the number, the more viscous or thicker, the oil is at higher temperatures. … 10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.

Is 5W-30 better for winter?

The oil’s cold weather rating is 5W30, which stands for winter and winter weather. Oil that has a lower W number will perform better in colder temperatures. Synthetic oils can flow even more easily when cold, which is why 5W oils are typically recommended for winter use.

Is it OK to use 5W-30 instead of 5w20?

Can You Use 5w30 Instead Of 5w20. It is not recommended. Although they both have the same winter rating of 5, the thickness (viscosity) of 5w30 is a bit higher than 5w20. That means your engine’s at stake for using the high viscosity oil.

Is it OK to use 10w30 instead of 5w20?

Originally Answered: Can I put 10w30 instead of 5w20? You can, but you will get worse mileage, and in most cases shorten the life of your engine, as it will take longer to pump up pressure for your bearings and lifters, and won’t spray your lower cylinders for an extra second or so on each cold start.

Can I use 5W-30 instead of 5W-40?

Registered. It’s not just the oil viscosity that’s important, it’s also the oil chemistry. As long as the oil you use is VW 502 certified, a 5W-30, 0W-30, 5W-40 or 0W-40 will work just fine.

Does motor oil thicken cold?

Cold Weather Slows the Flow of Oil

When you start your vehicle, its oil pump forces oil under pressure through the oil filter, main bearings and other parts of the engine. During cold weather, an engine’s motor oil becomes thicker.

Is 0w30 better than 5W-30?

It’s the viscosity or “flowability” or thinness of any oil that determines it’s fuel economy improvement capacity. The 0W-30 is thinner or less viscous than the 5W-30 which makes it considered as better for saving more.

Do you want thicker or thinner oil in winter?

When the weather turns cold, thicker oil has a harder time flowing through your vehicle’s engine and protecting all the critical parts with lubrication. … So, a 5W-30 or 0-W30 will give better protection in winter weather than, say, a 10W-40 or a 20W-50, while still providing solid high-temperature protection.
