So, what exactly is high mileage oil? As the name implies, this type of motor oil is formulated to address the specific problems encountered by high mileage vehicles, or those with more than 75,000 miles. It can help reduce oil consumption, smoke, and emissions from older engines.
What is the difference between regular oil and high mileage 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.
What is considered high mileage for an oil change?
It all depends on how the vehicle has been driven and maintained. Some people might consider switching to a high mileage oil at 200,000 miles, while others may want to change to a high mileage oil at 80,000 miles. For the average driver, anything over 100,000 miles could safely be considered a high mileage vehicle.
What is the difference between high mileage oil and full synthetic oil?
High Mileage with MaxLife™ Technology is created using a blend of natural and synthetic oils as its foundation, while Full synthetic High Mileage with Maxlife™ Technology uses an even more robust base of entirely synthetic oil. Either way, they contain similar additives to address the problems related to wear.
How often should you get a high mileage oil change?
It used to be normal to change the oil every 3,000 miles, but with modern lubricants most engines today have recommended oil change intervals of 5,000 to 7,500 miles. Moreover, if your car’s engine requires full-synthetic motor oil, it might go as far as 15,000 miles between services!.
Is high mileage oil a gimmick?
It’s a gimmick that can lead to damage. High mileage oils have additives to cause seals to swell under the guise of ‘reducing leaks’. These same additives cause those now swollen seals to get brittle and crack after several months which can lead to a severe oil leak resulting in engine failure.
Are high mileage oils worth it?
Reduced oil consumption: High mileage vehicles tend to leak and burn off more oil than younger cars due to degraded engine seals. High mileage oil rejuvenates degraded seals, which leads to less oil consumption and burnoff. Less engine sludge: Older engines tend to accumulate sludge left behind by other motor oils.
What is better full synthetic or high mileage?
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 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.
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.
Which high mileage oil is best?
10 Top-Rated Oils and Additives for High-Mileage Vehicles Valvoline High Mileage with MaxLife Technology Synthetic Blend Motor Oil. Pennzoil High Mileage Motor Oil. Slick 50 Recharged High Mileage Treatment. Gumout Fuel System Cleaner. Royal Purple High Mileage Synthetic. Techron Fuel Cleaner. Mobil Super High Mileage Oil.
Can you switch to synthetic oil with high mileage?
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.
Can you mix high mileage and 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.
Do synthetic oil changes last longer?
Longer Oil Change Interval: Some vehicles that require synthetic oil can wait up to 15,000 miles before an oil change because of the refined properties of the oil. Better at Higher Temperatures: Synthetic oil lasts longer than conventional oil because it doesn’t become as thick when exposed to extreme heat.
What happens if you go too long without an oil change?
Go long enough without an oil change, and it could eventually cost you your car. Once motor oil becomes sludge, it no longer draws heat from the engine. The engine might overheat and either blow a gasket or seize up. If the heat doesn’t cause a gasket to blow, it will warp the parts in your engine.
Is it OK to change oil once a year?
Many automakers have oil-change intervals at 7,500 or even 10,000 miles and 6 or 12 months for time. Even if you drive fewer miles each year than your automaker suggests changing the oil (say, 6,000 miles, with suggested oil-change intervals at 7,500 miles), you should still be getting that oil changed twice a year.
