Can You Mix 5W30 And 10W30 Reddit?

Can you mix 5W30 and 10W30 Reddit? This has been a question that many car owners have been asking lately. The answer is not as simple as yes or no, but it all depends on the circumstances.

Let’s take a closer look at this question so that you can make an informed decision about your own car. The main difference between 5W30 and 10W30 motor oil is the viscosity, or thickness, of the oil. Viscosity is important because it determines how well the oil will flow and lubricate your engine parts.

In general, thicker oils (like 10W30) are better for cold weather because they don’t thin out as much when the temperature drops. Thinner oils (like 5W30) are better for hot weather because they flow more easily and don’t get sludgy as quickly.

So, if you live in an area with extreme temperatures – like very hot summers and very cold winters – it’s probably best to use two different types of motor oil in your car.

During the winter, you would use a thicker oil like 10W30, and during the summer you would use a thinner oil like 5W30. However, if you live in an area with moderate temperatures year-round, then using one type of motor oil should be fine.

If you do decide to mix different types of motor oil together, be sure to add them slowly so that they have time to blend together properly.

Also, keep in mind that mixing different brands of motor oil together isn’t recommended since each brand has its own unique formula.

So if you’re going to mix different brands together, be sure to ask a professional first to make sure it’s safe for your car.

Can I Mix 10W30 With 10W40?

It’s generally recommended that you don’t mix different types of motor oil together. So if you have 10W30 in your car, you shouldn’t top it off with 10W40. The reason for this is that each type of motor oil has different properties and characteristics.

Mixing them together can result in a sub-optimal oil mixture that doesn’t provide the best protection for your engine.

If you’re unsure what type of motor oil to use, consult your car’s owner manual or ask a qualified mechanic.

Mixing 10W30 And 5W20

It’s no secret that motor oil is one of the most important fluids in your car. Not only does it keep all the moving parts in your engine lubricated, but it also helps to cool and clean those parts. Over time, oil breaks down and loses its effectiveness, which is why it needs to be changed regularly.

Most cars these days require a specific type of motor oil, typically either 5W20 or 10W30. However, there are some cases where you might need to mix these two types of oil. Here’s what you need to know about mixing 5W20 and 10W30 motor oil.

First, it’s important to understand the difference between the two types of oil. 5W20 is a lighter weight oil that is designed for use in newer cars with smaller engines. 10W30 is a heavier weight oil that works well in older cars with larger engines.

In general, you should always use the type of motor oil recommended by your car’s manufacturer. However, there are some circumstances where mixing the two types of oil might be necessary.

For example, if you’re topping off your Oil tank and only have one type of oil available, it’s better to mix it than not add any at all!

If you do find yourself needing to mix different types of motor oils, there are a few things to keep in mind.

First, make sure that you’re using oils with the same base stock – this will help ensure that they mix together properly.

Second, remember that adding more light weight oil (5W20) will thin out the mixture overall while adding more heavy weight oil (10W30) will make it thicker.

This can affect how well your engine runs so be sure to keep an eye on things after changing your Oil .

Lastly , don’t forget to dispose of any mixed Oil properly – check with your local automotive center for guidance on how to do this . While most people never have to worry about mixing different types of motor oils , knowing how to do so can come in handy in a pinch .

Just be sure to take care when doing so and always monitor your engine afterwards for any potential issues .

Can You Mix 5W30 And 10W40?

The quick answer is yes, you can mix 5W30 and 10W40 motor oils together.

However, there are a few things to keep in mind if you’re going to do this. First of all, it’s important to understand that the W in motor oil stands for winter.

The number following the W indicates how well the oil will flow at cold temperatures. The lower the number, the better the oil will flow at cold temperatures. Conversely, the higher the number, the thicker the oil will be at cold temperatures.

So, what does this mean for mixing 5W30 and 10W40? Well, since 5W30 is thinner than 10W40 at cold temperatures, mixing these two oils together will result in an oil that is somewhere in between the two in terms of thickness. This may not be ideal depending on your climate and driving conditions.

Another thing to keep in mind is that different motor oils have different additives in them. These additives can perform various functions such as protecting against wear or helping to clean your engine .

When you mix two different oils together, you may not be getting the full benefit of each additive since they could potentially cancel each other out .

Therefore , it’s always best to use motor oil that is specifically designed for your vehicle .

Can You Mix 5W30 And 5W20?

If you’re like most people, you probably don’t think twice about what type of oil goes into your car. As long as it’s the right grade and weight, you’re good to go, right? Well, maybe not.

It turns out that there can be some big differences between types of oil, even if they share the same grade and weight. So what happens if you mix 5W30 and 5W20 oil? It’s actually not recommended to mix different types of oil, even if they have the same grade and weight.

The reason for this is because each type of oil is formulated with a specific set of properties in mind. Mixing different oils can result in a mixture that doesn’t have the ideal properties for either type of oil.

In worst case scenarios, mixing different oils can actually damage your engine.

So what should you do if you accidentally mix different types of oil? The best course of action is to drain the entire system and start fresh with the correct type of oil. This may seem like a pain, but it’s worth it to avoid any potential problems down the road.

Is It Okay to Mix 10W30 With 5W30?

If you’re looking at the labels on your bottles of motor oil, you might be wondering if it’s okay to mix 10w30 with 5w30. The answer is technically yes, but there are a few things you should know before doing so.

For starters, mixing these two types of oil will result in an oil with an average viscosity.

This means that it will perform somewhere in between the two oils – not as well as either one individually. Additionally, it’s important to make sure that both oils are compatible with each other. Some oils aren’t meant to be mixed, so always check the labels before adding anything to your engine.

Finally, remember that mixing different types of oil can affect your car’s warranty.

So if you have any concerns, it’s best to check with your mechanic or dealership first.

Is It Ok to Mix 5W And 10W Oil?

While it is technically okay to mix 5W and 10W oil, it is not advisable. The reason for this is because the two oils have different viscosities, meaning they flow at different rates. Mixing the two together can cause problems with how your engine operates.

Is It Ok to Mix Motor Oil Types?

Motor oil is a lubricant that helps keep your car’s engine running smoothly. There are different types of motor oil, each with its own benefits and drawbacks. Mixing different types of motor oil can have some negative consequences, so it’s important to understand the risks before you do it.

One of the main reasons why you shouldn’t mix different types of motor oil is because it can cause sludge to build up in your engine. Sludge is a sticky, gooey substance that can clog up your engine and reduce its efficiency.

If you mix different types of motor oil, the sludge will be even more difficult to remove from your engine.

Another reason why mixing motor oils is a bad idea is because it can lead to inconsistent performance from your engine. Different types of motor oil have different viscosities, or thicknesses.

If you mix them together, they will no longer provide consistent lubrication for your engine parts.

This can cause increased wear and tear on your engine, leading to premature failure. If you need to add more motor oil to your car, make sure you use the same type that’s already in there. Mixing different types of motor oil may seem like a good way to save money, but in reality it will just end up costing you more in the long run.


If you are unsure about which oil to use in your car, you may be tempted to mix different types together. For example, can you mix 10W 30 with 5W 30? The answer is no.

Motor oil is designed to maintain a certain level of viscosity, or thickness, throughout its lifetime. Mixing different oils together can disrupt this balance, leading to engine problems down the road.
