What is considered high mileage on a car for 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..
Is 5w30 good for high mileage?
For example, a high mileage engine oil rated at 5W30 will flow better and has a superior viscosity at low temperatures when compared to an engine oil with a rating of 10W40. If you live in a cold environment, it is always best to go with a high mileage oil that has a lower SAE rating like 5W30.
Can I use 20w50 instead of 5w30?
20w50 is actually thicker than 5w30. This will result in less fuel efficiency, less horsepower, and more engine damage because it will have to work harder to rotate. Trust the engineers that made your vehicle.
What’s the difference between high mileage oil and synthetic?
In this respect, synthetic oil is far superior. Conventional oils will thicken in cold weather and thin out when very hot, while the viscosity of synthetic is much more uniform. … High Mileage Oil: Vehicles are lasting longer, and more than 2/3 of the cars on the road have more than 75,000 miles on them.
Is it bad to put thicker oil in your car?
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.
What happens if you 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.
Is 5w20 good for high mileage?
High mileage protection Mobil 1™ High Mileage 5W-20 is designed to help maximize engine performance and extend the engine life of vehicles with over 75,000 miles.
Is there a 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 it better to use 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 I mix 5w30 with 10w40?
As posted above, mixing 5w30 with 10w40 will give you an oil that performs somewhat better in the cold than 10w40, but less good cold than 5w30, and that has a viscosity a bit higher than 5w30 but a bit lower than 10w40. … Mixing different oils will not improve the performance or efficiency of the engine in any way.
Is synthetic oil good for high mileage cars?
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. After all, some mechanics have said to this author that engine oil is more important than fuel.
Is it better to use thicker oil in older engines?
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 10w40 good for high mileage?
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.
What is the best oil to use in a high mileage car?
Mobil 1Mobil 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.
Which oil is thicker 5w30 or 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.
Can I go from 5w30 to 10w40?
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.
Do high mileage oils work?
High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. … In addition to having seal conditioners, high-mileage oils usually boast more detergents designed to clean out sludge inside the engine, plus other additives meant to reduce wear on moving parts.
When should I use 20w50 oil?
Warmer Temperatures 20W50 motor oil is suitable for warmer climates, where the higher temperature causes the oil to thin. It is also useful for vehicles subject to hot temperatures and for those used for high-stress activities such as hauling or pulling trailers.
