When it comes to changing your car's engine oil, you may wonder if you can mix different types of oil. For instance, can you mix 10W-30 and 5W-30 engine oils? The answer is yes, but you need to understand what these numbers represent and why mixing them is not ideal.
First, the numbers on the engine oil bottle indicate the oil's viscosity or thickness. The "W" stands for winter, and the number before the W indicates the oil's thickness in cold temperatures. The lower the number, the thinner the oil, which means it flows more easily in cold weather. The number after the W indicates the oil's thickness at normal operating temperatures. The higher the number, the thicker the oil, which means it provides better protection against wear and tear.
Now, let's say you have some leftover 10W-30 oil in your garage, but your car's manufacturer recommends 5W-30 oil. Can you mix them? Technically, yes, because both oils have the same viscosity at operating temperatures. However, mixing them will result in an oil blend with a viscosity somewhere between 5W-30 and 10W-30, which may not be ideal for your car's engine.
Why is that? Well, car manufacturers design engines to work with specific oil viscosities for optimal performance and fuel economy. Mixing different viscosities can alter the oil's flow properties and reduce its effectiveness in lubricating the engine's parts. For example, if you mix 5W-30 and 10W-30 oils, you may end up with an oil that is too thick for your car's engine to pump efficiently, which can lead to increased wear and tear, reduced fuel economy, and even engine damage over time.
So, what should you do if you have different types of oil and want to use them up? The best practice is to stick to the oil recommended by your car's manufacturer and avoid mixing different viscosities or brands. If you have leftover oil that you cannot use, dispose of it properly by taking it to a recycling center or a mechanic who can recycle it for you.
In conclusion, while it is technically possible to mix 10W-30 and 5W-30 engine oils, it is not recommended. Mixing different oil viscosities can alter the oil's flow properties and reduce its effectiveness in lubricating the engine's parts. Stick to the oil recommended by your car's manufacturer for optimal performance and avoid mixing different brands or types of oil.
