Is 10w30 good for high mileage?

10W-30 motor oil makes for a decent high-mileage oil. It gives a better fuel economy while reducing the oil consumption for older engines. Older engines with more than 75,000 miles on them require a thicker oil that will properly lubricate their critical engine parts and prevent oil leaks, sludge, and deposits.

Is 5w30 or 10w30 better for high mileage cars?

5W-30 multi grade oil is ideal for private vehicles and light-duty petrol and diesel engines. It also provides a better cold temperature start than 10W-30 oil. On the other hand, the slightly thicker oil,10W-30, provides better lubrication for commercial vehicles and heavy-load engine cars.

Can I put 10w30 instead of 5w30 High mileage?

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.

What oil is best for high mileage cars?

Is Thicker oil better for high mileage cars?

The slightly thicker oil film from the heavier base weight oil - 10W - can help protect worn engine bearings as well. As long as you're not hearing knocking or serious mechanical noises from the engine, the heavier oil should buy you many more miles of service from your vehicle.

The importance of choosing the right engine oil quality and viscosity for your car or truck - VOTD

Will heavier oil hurt my engine?

Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.

Can high mileage oil damage an engine?

Using a high-mileage oil in a new vehicle would be ill-advised, since no manufacturer recommends this type of oil for a new vehicle. Would it harm your engine? Most likely not, but it would be better to adhere to what is specified in the owner's manual, at least until the warranty has expired.

Can I use 10w30 oil instead of 5w30?

The answer is yes. You can use 10w30 instead of 5w30 oil since both meet the SAE standard for viscosity at operating temperature. Generally, the viscosity difference between the two is neglectable.

What oil is best for old engines?

Which engine oil lasts the longest?

This is because synthetic oil is highly refined and can last longer than conventional oil. The refined quality of synthetic oil also gives your engine better performance, which is why it's often used on high-performance vehicles.

What is 10W-30 oil used for?

10W-30 motor oil makes for a decent high-mileage oil. It gives a better fuel economy while reducing the oil consumption for older engines. Older engines with more than 75,000 miles on them require a thicker oil that will properly lubricate their critical engine parts and prevent oil leaks, sludge, and deposits.

Is 10w30 good for winter?

10W30 vs 10W40 Oil FAQs

10W-30 motor oil is recommended for ambient temperatures not exceeding -30°C/-22°F in the winter or 35°C/95°F in the summer. This is a great motor oil to use if you live in Canada or cooler U.S. states. Colder regions would require 5W-20, while hotter regions may call for 10W-40.

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.

Is 5w30 or 10w30 better for summer?

Answer: There is absolutely no need to switch to 10W-30 motor oil in the summer if 5W-30 is an acceptable grade for your engine. While some car manufacturers still advocate the use of 10W-30 (or even 10W-40) as an appropriate engine oil option for summer use, it is completely unnecessary.

Can I put 10w30 instead of 5w20?

Notwithstanding the recommendations of the car manufacturer, mixing 10w30 and 5w20 will not cause any sort of harm to the engine. However, a few drivers claim that it is safer to combine two multi-grade or straight weight oils, rather than mixing multi-grade with straight weight oils.

Is 5w30 or 10w30 better for winter?

10w30, the thinner 5w30 will circulate quicker, and flow through bearing tolerances better during an engine startup in the winter or colder climates. The “w” behind the five and the 10 indicates that those are the viscosities in colder or winter temperatures.

Why do older cars need thicker oil?

Older engines use more oil, but it gives them a better fuel economy. Older engines with more than 75,000 miles on them require a thicker oil that will lubricate their critical engine parts and prevent oil leaks, sludge, and deposits from forming.

Is synthetic oil OK for older engines?

It protects better, performs better, and lasts longer, and it's no longer made with a chemical compound that could hurt older vehicles.

Is 20w50 good for high mileage?

Is 20W-50 Oil Good For High Mileage? 20W-50 is only used for certain older vehicles or worn engines that require the extra cushioning of a high viscosity oil. Other than that, it really isn't a high mileage oil.

What cars use 10w30?

In addition to high-performance turbocharged, supercharged, multi-valve fuel injected engines found in passenger cars, SUVs, light vans, and light trucks, Mobil 1 10W-30 is recommended by ExxonMobil for all types of modern gasoline-powered vehicles.

Will thinner oils damage your engine?

Just like using an oil with too high a viscosity may lead to problems in Brad's engine, using a thinner oil can have the same result. Oil that's too thin can fail to develop a consistent lubricating film, inviting metal-to-metal contact that causes wear. Extreme stress and heat add to the challenge.

What is considered high mileage?

What is considered high-mileage? Typically, putting 12,000 to 15,000 miles on your car per year is viewed as “average.” A car that is driven more than that is considered high-mileage. With proper maintenance, cars can have a life expectancy of about 200,000 miles.

Can I mix high mileage oil with regular oil?

High-mileage motor oil.

Mixing them will not improve the performance or efficiency of your engine in any way. Nor will mixing improve the oil performance, either. This is illustrated by these two equally important points: Adding synthetic oil to regular motor oil will not enhance the regular oil.

When should I use high mileage oil?

High mileage motor oil is designed specifically for older cars with high mileage (75,000 miles or more). Compared to regular motor oil, high mileage oil contains special additives that improve engine longevity.

Is 10W 40 too thick?

A low viscosity oil will move quicker through the engine to keep it lubricated and cool. Additionally, if your engine has a lower running temperature, 10W-40 motor oil might be too thick. Its higher viscosity at running temperature can reduce engine effectiveness as it'll need more energy to keep the engine operating.
