Taking care of a vehicle’s engine is super important, and one of the best ways to do that is by using the right engine oil. Engine oil does more than make the parts slippery; it actually protects the engine from damage caused by heat, friction, and wear.
But not all engine oils are the same. They come in different thicknesses, known as viscosity, which makes a big difference in how they work in your engine.
One question people often ask is: Can you mix engine oils with different thicknesses? Some bike owners and mechanics think mixing a little bit of one kind with another is okay, but others believe you should always stick to one type. In this blog, we’ll look at whether it’s safe to mix different oils and explain how to choose the best one for your vehicle. Let’s find out what happens when engine oils of different thicknesses are combined!
Engine oil viscosity is a way to measure how thick or thin the oil is and how easily it flows. It’s important because it affects how well the oil can protect the engine. Engine oils have a rating from the Society of Automotive Engineers (SAE), shown with two numbers and a “W” (like 5W-30).
The first number, before the “W,” shows how the oil flows in cold weather. The lower this number, the better the oil flows when it’s really cold, helping the engine start faster. The second number shows how the oil flows when the engine is hot. A higher second number means the oil will stay thicker and protect the engine well when it’s running at high temperatures.
Why is Viscosity Important?
Engine oil helps protect the engine by reducing friction, heat, and wear on important parts. The right viscosity (or thickness) makes sure the oil can flow easily to reach all parts of the engine, even when it’s really hot or cold. If the oil is too thick or too thin, it might not protect the engine well, which could cause more engine wear, lower gas mileage, or even engine damage.
Single-Grade vs. Multigrade Oils
Single-grade oils have just one thickness level and work best in specific weather. For example, SAE 30 oil is often used in warm weather because it’s thicker. Multigrade oils, like 10W-40, can work in both hot and cold temperatures. They have special ingredients that let the oil change thickness based on the temperature so that it can protect the engine in different kinds of weather.
Why are there Different Types of Engine Oil Thickness?
Engines need different oil thicknesses (called viscosities) because they work in all kinds of conditions, like super-cold winter mornings or really hot summer days. Here’s why different viscosities are needed:
- Temperature Changes: Engines can get really hot or really cold. Thicker oils (higher viscosity) are better in hot weather because they don’t get too runny, while thinner oils (lower viscosity) flow more easily in the cold, helping the engine start up smoothly.
- Cold-Start Protection: When it’s cold, engine parts need quick protection. Oils with a low “W” number, like 5W, flow quickly when it’s cold, giving the engine fast protection.
- Hot Weather Stability: When engines get super hot, some oils can thin out too much, which can reduce protection. Oils with a higher second number stay thicker in the heat, which keeps the engine safer.
- Fuel Efficiency: Some engines use thinner oils, like 0W-20, which help reduce friction and save fuel, giving you better gas mileage.
- Heavy Loads: Vehicles that carry heavy loads, like trucks, often need thicker oils to protect the engine parts from extra stress.
- Manufacturer Recommendations: Bike makers suggest specific oil types to keep the engine working its best. Using different oils might cause problems over time.
All these different needs explain why there isn’t a “one-size-fits-all” oil for every engine. Mixing oils that are too different in thickness can mess up this careful balance, which could hurt your engine.
What Can Go Wrong if You Mix Different Thicknesses of Engine Oil?
Mixing engine oils with different thicknesses might sound okay, but it can actually cause some serious problems for your engine. Here’s what could go wrong:
- Poor Protection: Your engine parts need a certain oil thickness to protect them from rubbing together. Mixing oils with different thicknesses can make the oil too thin or too thick so that it won’t protect the parts as well. This can cause more wear and even damage.
- Bad Oil Flow: Oil is designed to flow in a specific way to reach all parts of the engine. If you mix oils with different thicknesses, this flow can get messed up, so the oil might not cool or protect the engine parts properly.
- More Engine Wear: Mixed oils may not protect your engine from normal wear or a single type of oil. This can make engine parts wear down faster and hurt performance.
- Thick or Thin Oil Problems: Mixing oils can change how thick or thin the oil is. If it gets too thick, it may not work well in the cold. If it’s too thin, it may not protect well when the engine is hot.
- Clogged Oil Filter: Sometimes, mixing oils can create a sludge or goo that clogs the oil filter. This stops oil from flowing smoothly, which can make the engine overheat.
- Wastes More Fuel: If the oil isn’t the right thickness, the engine may have to work harder, which uses more gas.
- Warranty Issues: Bike companies recommend a certain oil thickness, and if you use something different, it could void your warranty. This means you’d have to pay for any repairs.
So, even though it might seem okay to mix oils, it’s best to stick to the right thickness recommended for your bike. That way, your engine stays protected and works its best!
Is It Okay to Mix Oils that are Close in Thickness?
You might wonder if it’s okay to mix oils that are similar in thickness, like 5W-30 and 10W-30. Here’s what you need to know:
- Small Differences: Oils that are only a little different in thickness, like in this example, probably won’t cause big problems right away. However, over time, these small changes could affect how the oil works in extreme conditions.
- Keep It the Same: It’s best to stick with the same type of oil. Mixing even similar oils can change how the oil works, which could affect your engine.
- Follow the Bike’s Instructions: Vehicle makers recommend a specific oil for a reason—they’ve tested it to work best for your engine. Using a different oil could cause issues later on.
- Long-Term Problems: Mixing oils might not cause problems right away, but it could lead to bigger issues down the road that are hard to figure out.
To keep your engine running well, it’s best not to mix oils. Always use the oil recommended in your motorcycle’s manual for the best performance and engine health.
Best Tips for Keeping Your Engine Oil in Good Shape
Taking care of your engine oil is important to make your motorcycle last longer and run better. Here are some simple tips:
- Change the Oil on Time: Follow the schedule in your bike’s manual for oil changes. Fresh oil with the right thickness keeps your engine running smoothly.
- Use the Right Oil Thickness: Always use the oil recommended in your bike’s manual. This helps the engine work well in different weather.
- Pick Good Oil: Choose high-quality oil that’s known to work well. Oils like Fubex are made to protect your engine and keep it running strong.
- Check Your Oil Level: Check your oil level often and add more if it’s low. If there’s not enough oil, your engine won’t be protected, and it could get damaged.
- Prepare for Tough Driving Conditions: If you drive in hot weather or tow heavy things, use oil that’s made for those tough conditions. It will help keep your engine safe.
What to Do if You Mix Different Engine Oils by Accident
Mixing different engine oils by mistake can happen, but it’s important to fix it as soon as possible to avoid damaging your engine. Here’s what you should do:
- Check the Mix: See how much of each oil you mixed and how different they are. If the oils are close in thickness (like 5W-30 and 10W-30), the risk might not be too bad.
- Change the Oil: If the oils are very different, it’s best to drain them out and put in the right oil your bike needs, as mentioned in the bike’s manual.
- Replace the Oil Filter: You should also change the oil filter, especially if mixing the oils could cause any problems with it.
- Watch the Engine: After you replace the oil, pay close attention to how the engine runs. If you hear strange sounds, notice it’s overheating, or if it doesn’t run as well, talk to a mechanic.
- Ask a Mechanic: If you’re not sure if there’s any damage or what to do next, ask a mechanic for help. They can give you the best advice.
- Prevent Mixing in the Future: To stop this from happening again, keep your oils separate and label them. Also, make sure anyone else who changes the oil knows which one to use.
Fixing the problem quickly is important, but the best thing is to always use the right oil for your bike and ask for help if you’re not sure.
