You have different options in choosing the right engine oil according to your vehicle’s requirements. You should read the manufacturer guidelines and find the perfect engine oil. Therefore, you should consider buying a thicker engine oil or the non-thicker or low viscosity engine oil. Still, I ask Can I Use 10w30 instead of 5w20?
If you have 10w30 and 5w20 oil, you can select any one of them by considering your engine requirements. If it is better for high thick engine oil, you can use the 10w30. However, if your engine requires low viscosity engine oil, you must use 5w20.
10w30 is used for higher viscosity engines. If you have a vehicle engine that requires high viscosity, you should use 10w30. You cannot use low viscosity oil because the thicker oil will handle the high mileage engine. But you cannot use any low viscosity oil for that engine.
Significantly, all the heavy load engines come with higher viscosity oil requirements. In that case, you must use 10w30 engine oil to get the optimum performance from that engine. Also, if your machine is required for 10 in low temperature and 30 viscosity in high temperature, you must go for 10w30 synthetic oil.
The 5w20 conventional oil is used for cold temperatures where you need to start the cold engine by using a low-viscosity oil. You cannot use high viscosity engine oil under cold weather or snowfall. You cannot turn the machine on by using 5w30 synthetic oil.
However, the 5w20 engine oil is an ideal choice for cold weather. Suppose you have a regular car and need to drive it in cold weather. So, it’s not like you must use the 5w30 under all weather, but you cannot use it for summer.
Yes, you can use 10w30 instead of 5w30 engine oil. They have similar ingredients other than the viscosity level. If you buy the engine oil and find it rated 10w30 or 5w20, you can rely on them.
It’s a clear indication that the 5w20 for low-viscosity engine oil. And the 10w30 is for a higher viscosity engine. You can mix them and use them accordingly. You have some 5w20 in your fuel tank, but you are planning to pour some 10w30. It will not damage your engine or reduce its performance.
You will find three reasons why you can use 10w30 instead of 5w20. They are explained below.
- Similar Ingredients: If you notice the ingredients of these two engine oils, you will find similar ingredients. They are made with synthetic oil and have enough quality to run the engine smoothly. You can easily use 10w30 instead of 5w20 unless it’s cold weather.
- Suitable for All Engines: These two engine oils are ideal for all engines. You can easily substitute them or use one instead of the others. They will keep running your engine smoothly. That’s why you can use 10w30 instead of 5w20.
- Don’t Damage Engine Performance: The logical reason you can use 10w30 instead of 5w20 is that they don’t damage the engine performance. So, you can mix them or use one instead of the others.
Yes, it is safe to mix 10w30 with 5w20 without damaging your engine. You can surely use one instead of the others or mix them. But try not to mix them willingly. If you have any 10w30 in your fuel tank, you can add 5w20. It will be safe.
The best substitute for 10w30 is 5w30. It has a similar viscosity level or other components. You can easily use the 5w30 in place of the 10w30. It will be safe for your engine.
You should not use 5w40 for 5w20 unless you’re in an emergency and don’t have any option. The 5w20 gives you the economical use of fuel that the 5w40 won’t give you.
If you ask, “Can I use 10w30 instead of 5w20”, the answer is positive. You can use them together or separately. There is no problem at all.
