Is it OK to use 10w30 instead of 5w30?

Is it OK to use 10w30 instead of 5w30?

Is it OK to use 10w30 instead of 5w30? Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.

Can you put 10W oil in a 5W car? Yes, if topping up. If your oil must be topped up, then you are burning oil already, so the difference won’t cause more damage than is already there. 5W30 and 10W30 are essentially the same at operating temperature.

When should I switch from 5w30 to 10w30? You don’t really need to change to the 10W30. The 5W and 10W are the numbers that tell you the low temperature behavior of the oil and the second number tells you the high temperature behavior. The oils only differ in cold weather viscosity. If you never see temperatures below zero F then either 5W30 or 10W30 is fine.

Can you put 10W 30 in a 5W 20 engine? Originally Answered: Can I put 10w30 instead of 5w20

Is it OK to use 10w30 instead of 5w30? – Related Questions

Should I use thicker oil in an older engine?

For an older, high-mileage passenger car, it is recommended to switch to a thicker viscosity oil, such as 10W-30, when approaching and passing 100,000 miles, to lubricate the engine well for preservation.

What happens if you 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 5w30 good for high mileage?

Amazon Basics Full Synthetic is the best 5w30 oil for high mileage vehicles. This oil should only be used on vehicles exceeding 75,000 miles. This motor oil is formulated for longer drain intervals. It helps in preventing a build-up on drain intervals and preventing rust and corrosion.

Is Thicker oil better for high mileage cars?

High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. Some mechanics recommend switching to a thicker (higher viscosity) oil — such as 10W-30 full synthetic oil instead of 5W-20 full synthetic — or using oil additives to stop leaks.

Should I use synthetic oil in my high mileage car?

Myth: Full synthetic oil is not good for high mileage cars or older vehicles. The myth is rooted in the idea that synthetic oil is “slipperier”—lower in viscosity, or not as compatible with seals and will therefore leak or leak more in places conventional oil might not. Again, completely untrue.

Is 5w30 or 10w30 better for summer?

5w30 is a great multigrade oil for use in low starting temperatures as well as high summer temperatures. It is also more fuel efficient since it creates less drag on the bearings and moving engine parts. 10w30 is thicker and may provide better sealing capability for older engines.

Will 5w30 hurt my 5W20 engine?

5W-30 and 5W-20 motor oil both feature the same winter rating. This means that both grades exhibit the same viscosity under cold conditions. 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 you mix 5w30 with 10w30?

Keep in mind oils do not mix if you have 5w30 and add 10w30 it won’t give you a blens both oils will stay seperate so you will have a few quarts 5w30 and a quart 10w30 they never mix. Mixing different oils will not improve the performance or efficiency of the engine in any way.

What happens if you use the wrong viscosity oil?

The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. Use only what the owner’s manual specifies. Using the wrong oil can lead to reduced lubrication and shorter engine life.

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 5w30?

If you put in 5W-30 oil instead of 5W-20 when the latter is the grade suggested by your vehicle’s manufacturer, damage to internal engine parts can occur. Additionally, your engine may experience performance issues such as diminished fuel economy and horsepower.

What oil is best for old engines?

When you’re choosing the best oil for older cars or high mileage engines, there are several criteria you can look at.
Pennzoil High Mileage Conventional Motor Oil.
Castrol GTX Part-Synthetic High Mileage.
Valvoline MaxLife High Mileage Synthetic Blend.
Mobil1 High Mileage Engine Oil.
Amsoil Premium Protection Motor Oil.

Can I switch from 10w40 to 5w30?

It’s better to switch to another brand of 10W-40 instead of switching to 5W-30. Yes you can change to total 5w-30 if engine is not reducing oil. It’s one of the best oils in market if you are getting it from total pump directly to avoid fakes.

Which oil is thicker 5w30 or 10w30?

10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.

What happens if you put thicker oil in your car?

Using motor oil with higher viscosity (oil that is too thick) also reduces your car’s overall fuel efficiency. This is because the thicker the motor oil, the higher its resistance on vital metal components, such as pistons.
