You own a new or low mileage vehicle and are unsure whether to use high or low mileage oil. Anyone would assume that high mileage oil is better for your car because it is superior on paper to low mileage oil. 

That is not always the case. In this article, we will learn when it is appropriate to switch to high mileage oil and whether you can use it in your low mileage vehicle or not. 

Let us first learn more about high mileage oil. 

What is Considered High Mileage Oil? 

High mileage oils are high-quality motor oils specially formulated to withstand extreme conditions. These oils are designed to protect engines from wear and tear and help them last longer, and are specifically engineered to withstand higher temperatures than regular engine oils. 

Here’s a quick video to solve your query on the topic.

What Can Happen from Using a High Mileage Oil in a Low Mileage Car? 

High mileage oil is typically used in older vehicles or those that have traveled more than 75000 miles. A high mileage oil will not harm a low mileage engine. It is a complete myth that using high mileage oil in a low mileage engine can cause wear and tear and overheating problems in your car. 

Although high mileage oil has no such drawback for your low mileage car engine, it also has no major advantage when used in new vehicles. It can be used as a preventive measure to reduce engine wear and tear in newer or low-mileage vehicles; however, it will not result in any significant improvement. In some cases, high mileage oil can benefit your low mileage car by improving its fuel economy, reducing damage, and increasing engine longevity.  

Can High-Mileage Oil be Used in Low-Mileage Cars? 

There are no hard rules for determining what qualifies as high mileage. If your car is experiencing corrosion, significant wear, leaks, or power loss even after using your regular oil, you can shift to high mileage oil and see the difference.  When going on long rides, you can use high mileage oil if your vehicle frequently overheats and exhibits degraded performance; if this does not make a difference, avoid buying high mileage oil in the future. 

It is entirely up to you whether or not to pay a premium for high-performance oil.  If your engine isn’t leaking or burning oil, or if it only needs a quart every 6,000 miles or so, switching to high-mileage oil may not be worth the extra cost. 

Signs That You Should Shift to High Mileage Oil 

Your vehicle is probably getting older and has run thousands of miles, and you’re probably wondering when you should switch to high mileage oil to avoid any wear and tear to engine components. Here are some signs that your car should be using high mileage oil: 

  • You see oil patches directly beneath where your car was parked. 
  • You can smell oil like gas or see oil stains on engine parts. 
  • Often hearing rattling sounds from the engine indicates that the engine parts are getting old. 
  • Overheating and performance issues during long rides 

Why should you switch to High Mileage Oil 

  1. Cleaner burning- When you run your car on high-mileage oil, it burns cleaner than regular oil. This means you won’t get any black smoke from your tailpipe. Switching to high-mileage oils could help reduce emissions. Also, High-mileage oils typically contain extra chemicals designed to remove sludge from the engine. 
  2. Last longer- If you use high-mileage oil instead, it’ll probably last much longer. This means that you don’t have to worry about running out of oil while you’re driving somewhere. 
  3. Better lubrication – High mileage oils are thicker (higher viscosity) and contain additional compounds for wear resistance, film strength, and so forth. They attempt to compensate for the increased gaps in piston rings and bearings. 

Why should you not switch to High Mileage Oil? 

  1. Cost ineffective – If price is the most important consideration while purchasing engine oil, you should look for low-performance oil as most of these high-mileage oils are more expensive. 
  2. Puffed seals – You can’t simply switch back to standard oil is a huge drawback with high mileage oil. When you use high mileage engine oil, the chemicals begin conditioning your engine seals and attempt to resurrect them. If you switch back to standard engine oil, your engine seals may shrink again, causing your engine to leak the oil. 


To summarize, yes, you can use high mileage engine oil in your low mileage automobile, given that your car is getting older and experiencing performance issues. If your car is brand new and has run limited miles, using low mileage oil will suffice for your car.

Aside from that, you can utilize it as a preventive precaution to avoid wear and tear in your engine components over time. High mileage oil has no side effect on the engine of your vehicle’s performance. In some cases, it is said to be slightly more beneficial for your engine components than regular engine oil. 


No oil of any sort will cause a leak. High mileage oil essentially acts as a detergent for your old engine. A leak will not be caused by cleaning detergents or softening seals. If you return to the low mileage oil, the stretched seals can leak.

Manufacturers recommend changing the engine oil every 10,000 to 15,000 km for high mileage engines and every 3000-5000 km for low mileage engines.
