Question: Does It Matter If You Use 5w20 Instead Of 5w30?

Is 5w20 oil good for winter?

The difference between 5W-30 and 5W-20 motor oil The thinner nature of 5W-20 oil also allows the oil pump to move it from the oil pan to the rest of the engine more easily.

This makes 5W-20 preferable for very cold climates, when having thinner oil that can flow easily on start-up is important..

What happens if you put 5w 20 in a 5w 30 engine?

Due to the increased resistance of the thicker 5W-30 oil, your engine will produce slightly lower fuel economy and horsepower output. You also risk engine damage when using 5W-30 instead of 5W-20, as the internal engine components are specifically designed to be used with 5W-20 motor oil.

What happens if I use 15w40 instead of 5w30?

5w30 provides best cold start properties. Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine’s crank. No it won’t blow off,you will just wear your engine out quicker because the oil won’t flow to the moving parts as quickly !

Is Thicker oil better for high mileage cars?

A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil — 10W — can help protect worn engine bearings as well.

When should I use 5w30 oil?

At operating temperatures, both oils will have the same viscosity (30) and will flow and protect identically. If the oil will be in the engine during winter and you live in a place where it gets cold during these months, use 5w30 oil. If it will only be in the engine during the summer, use 10w30.

Is it OK to use 5w20 instead of 5w30?

Probably not. 5w20 oil is fairly light oil and is generally designed to work with newer engines. Motor oil has become part of a manufacturers program to allow engines to get higher fuel mileage. Lighter oils take less HP to pump through an engine than heavier oils.

What happens if I 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.

Is mixing 5w30 with 10w30 bad?

Mixing different oils will not improve the performance or efficiency of the engine in any way. … 5w30 and 10w30 are both 30 weight oils and the exact same thickness in your engine when it is at operating temperature. The 5w30 is better because it thickens less when cool or cold. Thinner oil gets to the top end faster.

Is it okay to mix 5w30 with 10w40?

As posted above, mixing 5w30 with 10w40 will give you an oil that performs somewhat better in the cold than 10w40, but less good cold than 5w30, and that has a viscosity a bit higher than 5w30 but a bit lower than 10w40. … Mixing different oils will not improve the performance or efficiency of the engine in any way.

Can you put 10w30 in a 5w20 engine?

Originally Answered: Can I put 10w30 instead of 5w20? You can, but you will get worse mileage, and in most cases shorten the life of your engine, as it will take longer to pump up pressure for your bearings and lifters, and won’t spray your lower cylinders for an extra second or so on each cold start.

Which is better 5w 20 or 5w 30?

The thicker 5W-30 should see a slight advantage when operating at higher temperatures, while the thinner 5W-20 oil should provide better engine protection at lower temperature levels and has the added benefit of slightly improving fuel efficiency.

What will happen if I put the wrong oil in my car?

The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. … Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so.

What happens if I use 0w20 instead of 5w30?

0w-20 is simply a different viscosity of oil. It won’t be an advantage to your engine if your manufacturer suggests you use 5w-30 and may indeed be a detriment to your engine. 0w-20 may be a recommended oil for certain conditions for your engine and may not be recommended for your engine.

What happens if you put 5w20 instead of 0w 20?

Both 5w-20 and 0w-20 are IDENTICAL once the car is up to temperature. The difference is how thin those oils are when the car is cold. Neither the 0w or the 5w flow enough in the cold to properly lubricate your engine. However, the 0W is thinner and does LESS damage at start up than the 5W oil.
