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.
Will high mileage oil hurt a new car?
Using a high-mileage oil in a new vehicle would be ill-advised, since no manufacturer recommends this type of oil for a new vehicle. Would it harm your engine? Most likely not, but it would be better to adhere to what is specified in the owner’s manual, at least until the warranty has expired.
Is there a difference between regular and high mileage oil?
Most vehicle manufacturers would say it’s normal for an engine to consume some oil between oil changes. 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.
Can I use high mileage oil in my car?
Generally speaking, it’s safe to run synthetic oil in an older or high milage engine. That’s not what you might read online though. And there’s a reason for that. It used to be true that synthetic oil wasn’t good for older engines, namely because the additives in synthetic oils can damage the seals and gaskets.When should you 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.
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.
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.
Why is a high mileage bad?
Most people shy away from high mileage cars because they are “riskier” because they assume that with higher kilometers corresponds with things going wrong. … This is because at higher mileage, the depreciation curve of the car flattens out and you can put extra kilometers on the car without losing too much in value.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 high mileage oil thicker or thinner?Newer vehicles can utilize thinner oils for faster lubrication of new engine parts. In contrast, older, high-mileage engines benefit from thicker oils to prevent friction and oil loss.

Do high mileage cars need more frequent oil changes?
Car engines wear out as miles add up. Older engines and engines with high mileage have lower tolerances, making more frequent oil changes necessary.
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 put 10W40 in a 10W30 engine?
If you were to put 10W40 in an engine designed for 10W30, the “thicker” oil would lead to friction in the engine and an increased load on the oil pump. The car would have to do more work to get the oil around the engine block.
What happens if you use the wrong oil in your car?
Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.
What happens if I put 10W40 instead of 10W30?
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 mix engine oil?
THE ANSWER IS NO! Even if two different brands of oil have the same viscosity, you still should not be mixing them together. … Technically, using a grade of oil that’s recommended by your car manufacturer is correct. However, if you combine two different brands of motor oil, you could be at risk of damage.
When should I use 10W40 oil?
While both are low-temperature grade oils, 10W40 is thicker at high temperature; therefore, better to use in warm weather.
How many miles is high mileage?
What is considered high-mileage? Typically, putting 12,000 to 15,000 miles on your car per year is viewed as “average.” A car that is driven more than that is considered high-mileage. With proper maintenance, cars can have a life expectancy of about 200,000 miles.
What mileage is too high for a used car?
There’s no absolute number of miles that is too many for a used car. But consider 200,000 as an upper limit, a threshold where even modern cars begin to succumb to the years of wear and tear.
Is it better to buy a car with low mileage?
WHAT ARE THE ADVANTAGES OF BUYING A LOW MILEAGE CAR? Low mileage cars are typically seen as more desirable than high mileage counterparts because they’re essentially younger in terms of usage and can typically command more money on the used car market.
Is changing your own oil cheaper?
So to answer your question, no. Changing your own oil is not cheaper (unless you drive a Bugatti). If anything, it’s more expensive. But the little details like knowing exactly what’s in your car, and the pride of knowing you did it yourself, makes DIY oil changes worth the time, money, and overall struggle.
What oil is good for older engines?
If the car you’re maintaining is worth extra care and extra cost, Amsoil Premium Protection Motor Oil is pretty much the best you can get.

Do I need to change oil if I don't drive much?
It’s not just about miles: If you don’t drive your car a lot, your oil still needs to be kept fresh. 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.
Do I really need an oil change every 3000 miles?
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!
How long can you go without an oil change after its due?
WHEN TO GET AN OIL CHANGE Due to this, cars can generally go 5,000 to 7,500 miles before needing an oil change. Furthermore, if your vehicle uses synthetic oil, you can drive 10,000 or even 15,000 miles between oil changes.
Is it OK to mix 5w30 with 10w30?
No– you wont get the desired output by mixing these two oils. Because , both have different grades, 5w30 is more light and the density is less , and is intended for light usage (scooters). Whereas a 10w30 is a higer grade with more density and suitable for more higher capacity engines.
What does 10W30 stand for?
That’s why you see two numbers on most oils. For Example: 10W30. This means the viscosity is at 10W when the engine is cold and 30 when the engine is hot. Low viscosities are good for cold temperatures (hence the “W” association) because the oil is thinner. Thinner motor oil flows more easily and moves quickly.
Is 10W30 good for summer?
As a general rule, you’ll get the best protection in the summer when you use a slightly thicker grade of oil, such as a 10W30 instead of a 5W30. Engines need a thicker oil in the summer months because of the summer heat and its effects on thinning the oil out.
Is 10W30 good for winter?
A 10W flows well in cold weather, to protect the engine at start up, but it’s is too thin for use in the summer. A 30 grade oil, thick enough to protect in the heat, was recommended for summer use. … A 10W-30 had the winter cold start flow properties of a 10W and the summer, high-temperature thickness of a 30 grade.
