Question: Do High Mileage Oils Work?

Do you really need high mileage oil?

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..

Which is better 5w30 or 5w20?

The key difference between 5W20 and 5W30 motor oil is that the former is thicker or less viscous. … The more viscous motor oil is, the better it will be able to resist the heat and not break down. In this case, 5w30 oil will provide better overall engine protection than 5w20.

Does high mileage make a difference?

In general, buying a higher mileage newer is better than buying an older car with less miles. … On top of that, cars are meant to be driven so cars with higher mileage tend to last longer because car tends of lubricate itself more often and burns carbon build up which are all helpful for a long lasting engine.

Which oil is best for high mileage engines?

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.

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.

Which oil is thicker 5w30 or 10w30?

10w30 is thicker then 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil.

Is it OK to mix 5w20 with 5w30?

Can I mix 5W20 oil with 5W30 oil? Yes, you can. It is best if they are from the same brand and level of API service to be the same formulas, but they are certainly compatible, even if different formulas and brands.

How many miles can you go on high mileage oil?

The majority of automakers today call for oil changes at either 7,500 or 10,000 miles, and the interval can go as high as 15,000 miles in some cars.

Is 5w20 good for high mileage?

​5w30 or 5w20 for high mileage 5w-20 or 5w-30 oil can work effectively with a high mileage car. The former is more appropriate in cold weather, while the latter is advisable during a warmer temperature.

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.

Will thicker oil damage my engine?

Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.

When should I start using high mileage oil?

The first is to switch when your vehicle reaches 75,000 miles. The second is to switch if your older vehicle is beginning to show signs of engine loosening. If you notice an oil drip, that’s a sign you should start using high-mileage engine oil.

Can you go from high mileage oil to regular?

You can always go back to regular oil after using the High Mileage products.

Is it bad to put high mileage oil in a low mileage?

It can help reduce oil consumption, smoke, and emissions from older engines. High mileage oil also works to minimize leaks and oil seepage. While you could use high mileage oil in a younger car without harming it, the issues that high mileage oil addresses usually don’t appear in vehicles with fewer than 75,000 miles.

Is 5w 20 or 5w 30 better?

The thicker 5W-30 should see a slight advantage when operating at higher temperatures, while the thinner 5W-20 oil should provide better engine protection at lower temperature levels and has the added benefit of slightly improving fuel efficiency.
