Can I use 0w40 instead of 5W20?

Re: Can I use 0W-40 high performance synthetic oil
The 0 part means its got the cold-weather viscosity of any 0 weight oil, and will pour even thinner than 5W20 when cold. That's good.

Is 0W-40 thinner than 5W-20?

In fact, 0W40 is a substantial 28% thicker when cold, even though it is rated as a “0”wt when cold, which most people would expect to be thinner than a cold rated 5W. So, once again, you can see that the thickness of the hot viscosity rating, also affects the thickness of the cold viscosity rating.

What can you use instead of 5w20?

10w30 and 5w20 engine oils have similar SAE ratings, which means that they will perform similarly at operating or high temperatures. The number 30 indicates the viscosity of the oil at high temperatures, as stated before. 10w30 tends to get thicker in cold weather which makes 5w20 better suited for these environments.

What's the difference between 0W-40 and 5W-20?

When it gets hot it's entirely different, the 5W30 would do a better job because of it's thick viscosity, it will take more time for it to get thinner than the 0W40 that is thinner. Though both would work very well in Africa, but the 5W30 would do a better job in Africa and the 0W40 will deliver more in Europe.

Is 0W-40 the same as 5W 30?

With that said, 0W-40 is a thinner oil than 5W-30, an ideal oil weight for extreme temperatures, both winter and summer. On the other hand, 5W-30 works well for warm winters and summers because it's a thicker oil than 0W-40.

Can I use 0W 40 instead of 0W 20?

0w40 is MUCH heavier than 0w20. Using it, even once, can do serious damage to your engine if it's spec'd for 0w20.

What's the difference between 0W and 5W oil?

A 0W or 5W is a pointer to how easily each oil will flow in winter, ( W stands for winter). A 5W oil thickens more than a 0W ( 0W is thinner). So, in Winter, 0W-30 will be the most suitable oil to use.

Can I use 5w40 instead of 5w30?

In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.

Is 0W-40 good for BMW?

BMW M TwinPower 0W40 carries a LL-01 approval and is ACEA A3/B4 rated. This is the new BMW-approved oil recommended for turbocharged M engines that require extra protection at elevated temperatures. This oil is better suited for M turbo engines than the 0W30 "Fuel Efficient" oil used in non-M cars.

Can you use 0W 20 instead of 5W-20?

The 0W or 5W refers to the pumpability in cold temperatures. Therefore, a 0W would flow more easily than a 5W and could be an acceptable substitute. Thus, it is suitable to use a SAE 0W-20 as a replacement for SAE 5W-20 application. **Offers same protection as 5W but also provides faster flow and better fuel economy.

What is the difference between 0W 20 and 5W-20?

As 0W20 is a far thinner oil than 5W-20, it is more stable at cold temperature than the latter and flows smoothly through the critical engine parts. 5W-20 is a comparatively thicker viscosity oil and is better for a normal operating temperature range of -22°F to 68°F.

What oil is thicker than 5W-20?

When it comes to their higher operating temperature performance, 5W30 motor oil performs slightly better than 5W-20 and is a thicker oil than its counterpart. 5W30 motor oil would be more robust and not break down very easily at a higher temperature.

What is 0W40 engine oil?

Engine oil with class 0W40 is a multigrade oil and therefore exhibits good flow behaviour at cold and warm temperatures. The special temperature behaviour also enables the oil to be used in adverse conditions such as extreme cold. "0W" stands for the viscosity at low temperatures (W=winter).

Can I use 0W 40 instead of 0W 30?

For winter, the use of both 0w-30 and 0w-40 oils are equally good for this purpose and will do their job, the temperature range being somehow small but it can have a great impact on the engine overall, especially in higher temperatures.

What happens if you use wrong engine oil?

You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn't working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.

Can you mix 5w30 and ow20?

THIS. And now with a warmer summer no problem using 5-30 better protection, I would not use it if I had a 2010 or newer with less than 40k miles, but mixing should be ok, It will protect and no damage to worry about.

What happens if I use 0W-30 instead of 5W 30?

A 0W-30 grade can operate at much lower temperatures than a 5W-30 as the oil will flow faster thereby protecting the engine at an earlier stage. Some engines are not suited for a 0W-30, always check your owner's manual before adding oil to your engine.

What happens if I put 5W-20 instead of 5w30?

If you are using 5w20 instead of 5w30, you should be careful. The 5W20 is thinner and colder than the 5W10. The use of 5w20 in warmer temperatures may result in more friction and faster engine wear, as opposed to 5w30 in cooler temperatures. It will eventually affect your engine's performance and life expectancy.

Can I use 0w30 instead of 0w20?

Essentially 0w-30 does not protect your engine nearly as well as 0w-20 but is ideal for more extreme temperatures (temperatures of over 400°F). According to stikkitnow: While the 0w30 motor oil promises to protect your engine from tear, the 0w20 motor oil does this in a more outstanding and dramatic way.
