Quick Answer: What Is 10w 50 Oil Used For?

What is the difference between 10w 40 and 10w 50?

The difference between 10w40 and 10w50 is how thin the oil gets when it’s hot, 10w50 oil won’t thin out as quickly as 10w40 when oil temperature goes up, but it also might be too thick during regular running in cold temperatures (I think you’ll be fine though)..

What is the difference between 5w 40 and 10w 50 oil?

The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity). … However, the main difference between these two engine types is that the 5W40 can work better than 10W40 in very cold places.

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.

When should you use 20w50 oil?

Warmer Temperatures 20W50 motor oil is suitable for warmer climates, where the higher temperature causes the oil to thin. It is also useful for vehicles subject to hot temperatures and for those used for high-stress activities such as hauling or pulling trailers.

Can I mix 20w50 with 10w40?

Re: 20w50 and 10w40 mix The filter holds a good amount of oil, so yes, you will be mixing two different grades of oil which can lead to it congealing and cacking up all your oil ways.

For Example: 10W30 Low viscosities are good for cold temperatures (hence the “W” association) because the oil is thinner. Thinner motor oil flows more easily and moves quickly. When you start a cold engine up again, motor oil needs to travel to the top of the engine, where it trickles back down.

Can I use 10w 40 instead of 5w40?

10w40 is thicker than 5w40, ONLY when cold. At operating temperature it is exactly the same. … Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures. There is no need to use a 5w-40 if the vehicle only requires 10w-40.

What is the best oil for high mileage trucks?

Valvoline High Mileage with MaxLife Technology. … Castrol Edge High Mileage. … Mobil 1 High Mileage. … AmazonBasics High Mileage Motor Oil. … Pennzoil High Mileage Motor Oil. … Lucas Oil High Mileage Oil Stabilizer. … Royal Purple HMX High Mileage Synthetic Motor Oil.

When should you use thicker oil?

Within reason, thicker oil generally maintains a better film of lubrication between moving parts and seals vital components of your engine better. With the right additives to help it resist thinning too much in the heat, an oil can be rated for one viscosity when cold and another viscosity when hot.

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.

Which is better 15w50 or 20w50?

20W50 will maintain its viscosity for longer running than a 15W50. Ofcourse, everybody knows that 15W50 viscosity is better suited than 20W50, but practically, because of more shearing in case of 15W50, 20W50 is better and that is why most companies make 20W50 and not 15W50 when it comes to mineral oils.

What weight oil is best for high mileage?

The Best High Mileage OilValvoline High Mileage Motor Oil. … Castrol GTX High Mileage Synthetic Motor Oil. … Mobil 1 High Mileage 5W-30 Motor Oil. … Pennzoil High Mileage Oil. … Castrol High Mileage Advanced Full Synthetic Motor Oil. … Royal Purple High-Mileage Synthetic Motor Oil. … AmazonBasics High Mileage Motor Oil. … Mobil 1 High Mileage 5W-20 Motor Oil.

Can you mix 5w30 and 10w40 oil?

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.

Is 10w30 better 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.

Can I mix 20w50 with 10w30?

If you mix viscosity grades such as a 10W30 low-viscosity oil and a 20W50 higher-viscosity oil, it is reasonable to expect that the resulting product will have viscosity characteristics which are thicker than the 10W30, but thinner than the 20W50.

What happens if I put 5w40 instead of 5w30?

In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to temperatures of 50°C, as opposed to 30°C.

Can I use 10w 40 instead of 10w30?

Overall the 10W30 will be the more appropriate oil for cold weather and non-performing engines while 10W40 is perfect for warmer temperatures and older vehicles. But, if you are still not sure what to use, talk to your local mechanic or check the vehicle’s manual.

Which oil is better 10w40 or 20w50?

the huge problem is the other number though. The smaller number, (the 20 part of 20w-50) describes how the oil behaves at 40 deg C and a 20w at 40 deg C is about 10 times thicker than your engine wants. A 10w-40 is better at around 6 times thicker and a 0w-40 is much better at about 4 times thicker.

Is 20w50 good for high mileage?

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. The thickness is not meant for daily, older vehicle use.

Is Thicker oil better for older engines?

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.

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.
