Should I use different oil in the winter?



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. This way, they are able to pass tests that meet the 0W rating.

Do you need different oil in the winter?

Since lower-viscosity oils flow more readily, they provide better cold-weather startup protection compared to higher-viscosity oils. Thus it’s beneficial to switch to a lighter viscosity motor oil in winter if you can.

What oil is best for winter?

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 10W30 or 5w30 better for winter?





Low Temperature Viscosity



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 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 for winter?

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.

What synthetic oil is best for winter?

Overall, the best motor oil for cold weather is Mobil 1 Synthetic Motor Oil. It helps to keep your engine clean and running well. Our pick for the best value is Castrol GTX MAGNATEC 5W-30 Full Synthetic Motor Oil.

What happens if you use 5W-20 instead of 5W-30?





Mixing 5W-20 and 5W-30 (or any other oils for that matter) may lead to faster wear and tear of your engine and eventually cause problems with the basic functioning of critical engine parts. And even if your engine allows it, you won’t get any noticeable results by mixing different viscosity grade oils.

What temp is 5W-30 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 happens if you put 10w30 instead of 5W-30?

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).

Is synthetic oil bad in cold weather?

If your vehicle manufacturer recommends synthetic oil, you should use it no matter what the season. If your vehicle is older, synthetic will do a better job of lubricating engine parts in cold weather.

What is the disadvantage of synthetic oil?

Probably the most glaring downside of synthetic oil is the cost. The price of synthetic oil is around two to four times the price of conventional oil. Synthetics may be more prone to additives precipitation during cold storage conditions.



Does full synthetic oil freeze?

What Engine Oil Should You Use in the Winter? [4k]

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.

Should I use 5W-30 or 5w40?

5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.

Is 5w40 good for winter?

5w40 and 5w30 motor oils have winter viscosity grades of five, meaning they are effective down to temperatures of -30°C, and are more viscous at very low temperatures, compared to, say, 10w40 oils.

Which oil is thicker 5W-40 or 5W-30?

Although both have the same viscosity grade in cold weather, 5W-40 is thicker than 5W-30 at warmer temperatures. It’s also worth pointing out that: 5W-40 is the suggested oil for most diesel applications. Rarely (if ever) do vehicle manufacturers recommend putting 5W-40 oil in a gas-powered engine.
