Is it better to use thinner oil in winter?
When the cold weather comes, you want a lower number, meaning thinner oil, which will smoothly coat the insides of your engine even in the most frigid 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.
What is the difference between summer oil and winter oil?
Drivers would use a winter grade oil during cold weather, since it was designed to be thin and flow more easily in low temperatures. In the summer, they would swap out their winter oil for a thicker one, since hot temperatures thin out oil. They offer a wider range of protection for temperatures all year round.
Is Thicker oil better for cold temperatures or is thinner oil better in cold temperatures?
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.
What’s the difference between winter oil and summer oil?
Oil flows at different rates in different temperatures; thinner in colder wintertime, and thicker in the heat. Multi-viscosity oils mean you never have to switch back and forth because it’ll adapt itself.
What happens if your oil is too thick in cold weather?
Oil that’s too thin, explained Nunez, will not provide sufficient protection for your engine. Oil that’s too thick will keep your engine from starting in cold weather because the thick, gooey oil challenges your battery and starter motor to spin the engine fast enough for it to fire.
Which is better thinner oil or thicker oil?
A thinner oil reaches the engine parts quicker, and circulates faster, while a thicker oil tends to adhere more easily to the engine parts, and will provide better lubrication when engine tolerances have deteriorated, or in severe-duty applications like racing or off-road engines.
When to use lower viscosity motor oil in 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. Lower-viscosity oils also provide less crankshaft resistance as the engine turns over.

Is it OK to use thin oil in the winter?
Thin oil may not coat friction points properly, but thick oil won’t move quick enough to keep your engine moving. Driving in winter exposes your vehicle to extreme temperature fluctuations.
Do you really need to use heavier oil in summer?
It used to be that changing oil weight for summer or winter months was part of proper maintenance. Old conventional oil formulations had only one viscosity, and oil would thin out as it was heated. In winter months this caused starting trouble because the oil would turn to molasses and the pumps couldn’t lube the engine properly.
When to use lower viscosity oil or thicker oil?
To recap, a lower oil viscosity number indicates a thinner oil that will flow faster, while higher oil viscosity number indicates a thicker oil which often works better in extreme applications. For engines that do not have a recommended weight – winter and colder temperatures, you should use a lower viscosity oil for cold start up.
