What oil is better for a high mileage engine?
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.
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.
What oil is recommended for cars over 100k miles?
Castrol GTX High Mileage motor oil is a blend of traditional motor oil and a series of special additives to make it more suitable for high mileage engines. While a synthetic blend won't work as well as a fully synthetic oil, it's the next best thing and still a step above conventional oil.
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 5w40 better for high mileage cars?
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 engine 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.
What oil should I use for 150000 miles?
Valvoline High Mileage 150K with MaxLife Plus Technology Motor Oil offers high-mileage engines better protection against the four major causes of engine breakdown – wear, friction, heat, and deposits.
Can high mileage oil damage an engine?
High-mileage motor oil doesn't hurt and it could prevent leaks from starting. Most vehicle manufacturers would say it's normal for an engine to consume some oil between oil changes.
Should I use synthetic or conventional oil?
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 5W-20 or 5W 30 better for high mileage?
As you have likely now concluded, 5W20 is better suited for colder temperatures. If you need motor oil for summertime performance, 5W30 is going to be the better bet. However, you should only switch to this oil type of your car manufacturer or personal mechanic recommend doing so.
Is 5W-20 oil good for high mileage?
Designed for high mileage vehicles
Mobil 1 High Mileage 5W-20 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils†), including: Cars. Trucks.

Which is better 10w50 or 20w50?
10w50 is thinner than 20w50 at low temp. So it will flow between every small parts and gives better cold start as compared to 20w50. First number lower than recommended and second number higher than recommended is good. You can go for 10w50.
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 10w30 instead of 5w30 High mileage?
The answer is yes. You can use 10w30 instead of 5w30 oil since both meet the SAE standard for viscosity at operating temperature. Generally, the viscosity difference between the two is neglectable.
What happens if I use 5w40 instead of 5w30?
In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.
Can I use 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.

How long does high mileage oil last?
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!
Should I use 10w30 or 10w40?
There's not much difference between 10W-30 and 10W-40 motor oil. What sets them apart has more to do with temperature fluctuations and engine load. For moderate weather, either engine oil grades should work fine. Your choices will become more critical when you start getting into high-heat situations.
Which is better high mileage oil or synthetic?
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 I mix high mileage oil with 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. This is illustrated by these two equally important points: Adding synthetic oil to regular motor oil will not enhance the regular oil.
