What oil does a high mileage car take?

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 oil is recommended for high mileage cars?

High mileage oil is designed for vehicles with more than 75,000 miles. Such oil features additives that help protect seals. This leads to less leakage and oil burn-off, which can be common in older cars. If your vehicle is high-mileage and high performance, it's suggested that you go with this type of synthetic oil.

Does a high mileage car need high mileage oil?

Who needs high mileage oil? Cars with more than 75,000 on their odometer can usually benefit from high mileage oil. Older vehicles with fewer miles can benefit too, as engine seals can erode over time regardless of mileage. Degraded seals mean leaking oil, and leaking oil means your engine isn't working at its best.

Do high mileage cars need synthetic oil?

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 good for high mileage cars?

Mobil 1 High Mileage 5W-30 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils^†), including: Cars. Trucks.

My Favorite Engine Oil for High Mileage Cars and the Reasons Carefully Explained

Is 10w40 good for high mileage?

Mobil 1 High Mileage 10W-40 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils^†), including: Cars. Trucks.

Is 10w30 better 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.

Will synthetic oil damage a high mileage engine?

Your Mileage May Vary

Naturally, every situation is different. However, if a vehicle has been well maintained and is in good running condition, synthetic oil may very well prolong its life.

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.

Is there a difference between high mileage oil and regular oil?

What makes high-mileage engine oils different? High-mileage oils have ingredients to take care of older engines, like conditioners, seal swells, antioxidants, detergents and wear or friction additives. Typically they use a viscosity modifier that is durable and won't lose viscosity very easily.

Why do high mileage cars burn oil?

In order to reduce friction and achieve additional fuel economy, the auto manufacturers have reduced the piston ring tension. This ring tension change has resulted in small amounts of oil getting past the piston rings into the combustion chamber where it is burned.

Can I use 10w30 instead of 5w30?

According to API motor oil guide [1], If you are using 10W–30, you can safely switch to 5W–30 (in car engines). 5W–30 is thinner than 10W–30 when cold. (you must follow the manufacturer's recommendations). However, switching from 5W–30 to economical 10W–30 is not always recommended.

How often should high mileage oil be changed?

The quick-lube chains usually recommend it be done every three months or 3,000 miles, but many mechanics would tell you that such frequent changes are overkill. Indeed, most car owner's manuals recommend changing out the oil less frequently, usually after 5,000 or 7,500 miles.

Which is better 5w30 or 5w40?

5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.

Which car 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.

Which is better 10w30 or 20w50?

It really comes down to personal preference. As your engine does put out significant horsepower, we would lean toward using 20W-50. If your engine sees very light duty or is built exceptionally tight, 10W-30 would be fine. But again, if you twisted our arm, we would give 20W-50 the nod for the thicker viscosity.

Should I use 10w40?

So, if you drive in a warm climate — especially more than 32°C (90°F) — or have an engine that runs hotter than others, 10W-40 oil viscosity is a good option. This higher viscosity oil is designed for hotter temperatures and can handle the added heat stress from the environment.

Which oil is thicker 10w40 or 20w50?

10w40 oil is a popular all-purpose oil designed in many different engines. 20w50 (also known as 10w30) is another popular all-purpose oil used in engines. The differences between 10w40 and 20w50 are small, but they have something in common: They are thicker than regular 20w50 oil.

When should you not use synthetic oil?

Better For Older Engines

This being said, however, it is still not recommended to use synthetic oil in engines that have experienced significant actions – specifically, those that have reached around 75,000 miles on the odometer.

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

Lubrication. 5w30 provides better lubrication compared to 10w30. It is best suited for private vehicles and light-duty diesel and petrol engines, while 10w30 is more suitable for commercial vehicles and other cars with heavy load engines.

Is 5w30 or 10w30 better for high mileage?

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 10W40 instead of 5w30?

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.

What happens if I use 10W40 instead of 10W30?

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.

Should I use a thicker oil?

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 you just add oil instead of changing?

Topping up your oil is typically not recommended unless the level is below the minimum mark. If you're running low on oil, however, topping off may help you get to your nearest Firestone Complete Auto Care for an oil change service.
