Can I Put 5w30 Instead Of 5w40?

Can I mix 5w30 with 5w40?

Mixing different oils will not improve the performance or efficiency of the engine in any way.

The additives in synthetic oil may have limited or no effect at all when mixed with a regular engine oil.

You can use 1 litre of 5W30 mixed with 5W40 and it will not cause any sort of ill effects to the engine..

What can I use instead of 5w30?

A 10w30 oil tends to move slower than a 5w30 oil during cold startups. This is perhaps the major difference between these two oils. Both oils have the same viscosity with is 30, at operating temperatures.

What does 5w 30 stand for?

multigrade oil5W-30 means that this is a multigrade oil. This is indicated by the two numbers separated by a “W” 5W – shows thickness/viscosity of the oil on a start-up – when you start the car (W – stands for Winter, this indicates oil performance under colder engine temperatures when the engine has not been running)

Whats the difference between 5w30 and 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.

Which oil is thicker 5w40 or 5w30?

The working viscosity of 5w30 is basically from 9.3 to 12.5mm2/s whereas the operating viscosity of 5w40 is 12.5 to 16.3mm2/s. That means 5w40 has larger viscosity than 5w30.

Is 5w30 good for high mileage?

For example, a high mileage engine oil rated at 5W30 will flow better and has a superior viscosity at low temperatures when compared to an engine oil with a rating of 10W40. If you live in a cold environment, it is always best to go with a high mileage oil that has a lower SAE rating like 5W30.

Is 5w30 good for old cars?

In general thinner oils flow faster and lubricate better, and keep the engine parts cooler. using a thicker oil is asking for trouble. So if your original specification calls for 5W30, I wouldn’t change it. … It protects the engine due to lower levels of friction.

What does 5w40 mean in oil?

5w40 engine oil has a winter viscosity grade of five, meaning it’s less viscous at very low temperatures, compared to, say, 10w40. It has a hot viscosity grade of 40, which means it is just as viscous as 10w40 at high temperatures but less viscous than oils such as 15w50.

Can I use 10w 40 instead of 5w40?

10w40 is thicker than 5w40, ONLY when cold. At operating temperature it is exactly the same. … Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures. There is no need to use a 5w-40 if the vehicle only requires 10w-40.

What happens if I use the wrong 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.

Are all 5w30 oil synthetic?

When it’s brand new, a 5W-30 conventional motor oil acts exactly like a 5W-30 synthetic motor oil. Over time, however, the chemical additives used in the conventional oil to alter its properties begin to break-down, vaporize, or get used up.

Is SAE 30 oil the same as 5w30?

No. SAE 30 is a single viscosity motor oil. Only multi viscosity motor oils only should be used in any car. … 5W30 is motor oil that is thinner when cold than 30 weight motor oil and thicker than 5 weight motor oil when hot.

Does it matter what 5w30 oil I use?

If your car takes 5w30 oil and you put 5w30 oil in it, it’ll be fine. Totally wrong, these days the spec compliance of an oil is often more important than the viscosity. Don’t put any 5w30 in, put the correct 5w30 in.

Will 5w40 hurt a 5w30 engine?

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 temperatures of 50°C, as opposed to 30°C.

Can I put 5w40 in my BMW?

The Castrol oil that BMW used to spec was midway between a 30 and 40 weight. Anything from 0W30 to 5W40 will be fine if it has the LL-98 or LL-01 rating. You don’t even need that if you are running shorter change intervals.

What happens if you put 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.

What oil is best for my car?

Most modern cars work best on synthetic oils, while turbo-diesel engines like semi-synthetic, and older, classic cars prefer mineral. Again, your car’s manual will specify which type of oil you should be using.
