Question: What Oil To Use For High Mileage Car

Mobil 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 engine oil should I use for a high mileage car?

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.

Is 5w30 good for high mileage?

5W-30 motor oil is the top viscosity recommendation by automakers over the past four decades for use in many vehicle types. Furthermore, high-mileage 5W-30 motor oil is specially formulated for late model vehicles or newer vehicles with over 75,000 miles/120,000 kilometers.

Can you use regular oil in a high mileage car?

High mileage oil is designed for vehicles with more than 75,000 miles. As a rule of thumb, most new cars require synthetic oil. Older cars generally run well with conventional oil, unless your vehicle has more than 75,000 miles on it, in which case high-mileage oil is recommended.

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.

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.

Do you really 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.

Which oil is better 5w30 or 10w30?

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.

Which is better high mileage oil or synthetic?

So which one is better? The short answer is full synthetic is always better, but cost is the main reason why I buy high mileage oil vs synthetic oil. If you have over 75,000 miles on your modern car or truck, consider switching to a high-mileage motor oil.

What is the difference between high mileage oil and regular oil?

High-mileage oils have ingredients to take care of older engines, like conditioners, seal swells, antioxidants, detergents and wear or friction additives. The higher-mileage oils are formulated with seal conditioners that increase flexibility and restore shape, which can help prevent leaks in the long run.

Is Full synthetic oil Better?

Is synthetic oil better for my engine than conventional oil? Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can’t compete with the overall engine performance and protection provided by synthetics.

Is high mileage oil thicker?

High mileage oils contain viscosity modifiers that are durable and won’t diminish over time. This causes the oil to stay thicker for longer periods of time, helping protect your engine parts.

Is 10W40 better than 10w30?

The higher the number, the more viscous or thicker, the oil is at higher temperatures. 10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.

Can I switch from 5w30 to 10W40?

If your handbook recommends SAE 5W-30 AND SAE 10W-40, then you can change by all means, but the only difference will be slightly worse fuel economy and slightly harder starting when cold.

Can you switch from 5w30 to 10w30?

The oils only differ in cold weather viscosity. If you never see temperatures below zero F then either 5W30 or 10W30 is fine. If winter temperatures are regularly below 0 degrees F then 5W30 is what you should run and you can run it year round if the 30 weight is good according to your owner’s manual.

Is it OK to use 10W40 instead of 10W30?

Similarly, SAE 10W-40 motor oil performs well in cold weather conditions. It has the same low-temperature limits as the 10W-30 but is better in higher temperatures. Either 10W30 or 10W40 for summer use is fine; however, 10W-40 motor oil will better protect your engine.

What is 10W 50 oil used for?

10W50 oil is a high-performance engine oil that offers outstanding engine reliability and temperature stability under extreme driving conditions. It’s used for a wide range of motorsports and modern engines with turbochargers.

What does 10W30 mean?

Answered January 07 2020. The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold and 30 when the engine is hot. This is different than an oil labelled 5W30, which has a thinner viscosity when the engine is cold at 5W.

Is 20w50 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. This is because 20W-50 is a thicker oil, and the added resistance can cause further engine wear and damage to both newer and older vehicles.

Does oil brand make a difference?

As long as the oil weight and certifications match what your car needs, there is no point in paying extra for a brand name. The answer is they’re all interchangeable so long as they meet the oil weight and certifications for your vehicle.

What happens if you use 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.

Can I use 5W 20 instead of 5w30?

5W-20 oil, being the lower viscosity oil (thinner oil) than 5W-30, might help boost your fuel economy. And although you may not notice a vast difference, it does add up over time. However, remember that you should always use the motor oil recommended for your car by your engine manufacturer or mechanic.

Is 5w30 thicker than 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.
