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.

Should I use thicker oil in a high mileage engine?

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.

At what mileage should I use thicker oil?

Identification. 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 is the best oil for high mileage trucks?

Comparing the Best High Mileage Motor Oil

• Best High Mileage Motor Oil Overall. Pennzoil High Mileage Motor Oil. ...
• Best Value Oil. Mobil 1 High Mileage Motor Oil. ...
• Best Budget Motor Oil. Castrol GTX High Mileage Motor Oil. ...
• Best Premium Oil. Amsoil High Mileage Motor Oil. ...
• Also Consider. Valvoline MaxLife Higher Mileage Motor Oil.

Is synthetic oil bad for high mileage engines?

It's not accurate to say that you should never use synthetic oil in an older car. In fact, Castrol EDGE High Mileage is a synthetic oil designed specifically for high-mileage cars. If the car has been maintained and is in excellent running condition, the synthetic oil may protect the vehicle and prolong its life.

Is 10w40 good for high mileage?

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 10w40 oil?

Ambient Temperature This is the reason your location is so important in selecting which oil to use. Between a 10W-30 and 10W-40, 10W30 motor oil would run smoother in colder climates while a 10W40 would be more effective in preventing engine wear and tear in warmer temperatures.

Which is better 5w30 or 10w40?

The difference is in the viscosity of each at different temperatures. ... The 5w30 oil will flow better at low temperatures than the 10w40 oil. This means that the 5w30 oil will protect the engine better at low temperatures, usually when the engine is just starting or during weather conditions such as winter.

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.

Does 10w40 hurt 5w30 engine?

Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

Which oil is thicker 5w 20 or 10w 40?

For 10w40 motor oils, they tend to be a bit thicker than the 5w40 but still, rather thin and tend to work well in lubricating moving parts of engines during startup.

Which oil is better 0W20 or 5w20?

The smaller the number, the better the motor oil will flow. A 0W20 will be more fluid than a 5W20 at startup temperatures but will perform the same way at standard engine operating temperatures. Remember, engine oils naturally thicken as they cool down and thin as they are heated.

Will it hurt to use 5w20 instead of 0W20?

Yes you can use both. 0w-20 just provides better engine protection when starting up in cold cold winters. You should use what's specified in the owner's manual.

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.

Is it OK to put 5w30 in a 0W20 engine?

0w20 is a fully synthetic motor oil. ... 5w30 can be fully synthetic, however, putting it into your engine which is designed for 0w20 is a bad idea. If it isn't on the fill cap don't put it in your engine.

Does 0W20 damage engine?

Answer: Yes, 0W-20 is unquestionably safe for your engine. Manufacturers have been specifying 5W-20 and 0W-20 since the early part of the last decade and there is no evidence whatsoever that engine wear rates have increased.

What's the difference between 0W20 and 5W20 motor oil?

So, 0W20 means the oil's viscosity is 0 in cold temperatures and 20 at the operating temperature. The 5W20 oil is the same except for a viscosity of 5 in cold temperatures. Both oils are designed to use in cold-weather regions. However, these multi-grade oils can perform in hot weather too, although not extremely hot.

Is mixing 5W30 with 10w30 bad?

No- you wont get the desired output by mixing these two oils. Because , both have different grades, 5w30 is more light and the density is less , and is intended for light usage (scooters). Whereas a 10w30 is a higer grade with more density and suitable for more higher capacity engines.

What happens if you put 10W oil in 5W?

In winter the 5W will flow like a 5W oil and a 10W will flow like a 10W oil just until the engine reaches operating temperature. This multi-grade performance allows faster oil flow during cold start, however when the oil warms up, they both reach the designated 30 weight viscosity.

Can you mix 10W30 and SAE 30?

Yes, you can make use 10W30 engine oil instead of the SAE30 in your Lawn Mower. Older engines can use the SAE30, while the 10W30 is for modern engines. Again, the SAE30 is better for warmer temperatures while the 10W30 is suitable for varying temperature ranges and also works well in cold weather.
