Should I use 5w30 or 10w40?
The one, 5w30, will be able to flow better when the temperatures are low than the 10w40.
So at a lower temperature, the 5w30 oil will be the best to protect the engine.
When at high temperatures, the 5w30 oil becomes thinner than the 10w40 oil since 30 is lower as compared to 40..
Does oil get thicker as it warms up?
Oil weight, or viscosity, refers to how thick or thin the oil is. … Your engine needs oil that is thin enough for cold starts, and thick enough when the engine is hot. Since oil gets thinner when heated, and thicker when cooled, most of us use what are called multi-grade, or multi-viscosity oils.
Should I use thicker oil in a high mileage engine?
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.
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.
What happens if you put wrong oil in your car?
You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.
What happens if you don’t change your oil for 10000 miles?
Depending on the vehicle and oil, the time between oil changes could range from 3,000 to 10,000 miles. But what happens if you decide to skip oil change? The end result is that your engine won’t last as long as it could. It might also mean an extravagant bill for an engine replacement or a sooner-than-expected rebuild.
Which oil is thicker 5w30 or 10w40?
A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.
Does oil go bad if you don’t drive?
Oil that degrades too much can cause engine sludge that can block oil flow entirely. Even if you don’t drive very often and you’re not hitting the recommended mileage interval, it’s best to get your oil changed twice a year. Your oil may be fine, but it’s the moisture in your engine that’s the real enemy.
Is 5w30 good for high mileage?
Both high mileage 5w30 and 10w30 engine oils have the same additives, the only difference is the viscosity at cold startups. Since both oils have the same operating temperature viscosity (30) and additives, they will perform exactly the same. However, 5w30 flows much better than 10w30 during cold starts.
Will a thicker oil hurt my car?
Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.
Is it a good idea to put synthetic oil in older cars?
Using synthetic oils in older models The synthetic oil could leak out and the vehicle could burn or lose oil. … Because synthetic oil does a better job of cleaning out sludge, it could remove deposits that are acting as seals. It’s not accurate to say that you should never use a synthetic oil in an older car.
Is 20w50 good for high mileage?
Considerations. The viscosity level of engine oil 20W50 is geared toward racing engines, as opposed to high-mileage engines, that run extremely hot and need heavy load operation. … Since its viscosity is so great, it can drag down the functioning of the crankshaft, resulting in less horsepower.
What is the best oil to use in a high mileage car?
Mobil 1Mobil 1 High Mileage If you know your vehicle has received regular oil changes at the manufacturer’s Mobil 1™ High Mileage synthetic motor oil is the best choice. Why? This high mileage oil contains a higher base oil viscosity to help reduce leaks and provide better high temperature protection.
What happens if you put thicker oil in your car?
The higher the number, the thicker the oil. Thicker oil protects engine parts better than thinner oil under tough conditions. For instance, if you’re driving in Arizona in the middle of summer, a 20W-50 motor oil would protect your engine better than a 5w-20 viscosity.
Does 10w40 hurt 5w30 engine?
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.
How long can you drive on synthetic oil?
Davis says that educated drivers should opt for longer lasting, better performing synthetic oils, which are “most likely good for 10,000 to 15,000 miles or six months” whether or not their manufacturers recommend more frequent changes or not.
Should I use thicker oil in an older engine?
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.
Can you go over 10000 miles with synthetic oil?
Full synthetic oils will actually last well beyond 10,000 miles. The lifespan of synthetic oil depends, but it’s not crazy to see oils still working at 15,000 miles or longer. … Our standard recommendation is 7,500 miles for a normal vehicle based on the thousands of engine repairs we’ve seen over the years.
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 it OK to 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 I put 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.
