STP Motor Oil Review: My Top Pick

STP Motor Oil Review: Which One is the best?

STP motor oil is a petroleum-based product that is designed to lubricate and protect car engines. It is available in a variety of grades, each of which is designed for use in specific types of engines. The most common type of STP motor oil is 10W-30, which can be used in both gasoline and diesel engines. 

STP motor oil is also available in higher viscosity grades, such as 20W-50, which are designed for use in high-performance engines. In addition to its lubricating properties, STP motor oil also contains additives that help to protect against wear and tear. 

These additives include antifoam agents, anti-rust inhibitors, and anti-wear additives.

๐Ÿš— STP Motor oil 5w-20 Review


โœ… On the plus side, this oil is designed for extended drain intervals. That means you can go longer between changes, which can save you time and money.
โœ… It’s also compatible with a wide range of engines, including those with turbochargers or direct injection.


โŒ However, there are a few potential drawbacks to keep in mind as well. First, this oil may not work as well in extremely cold temperatures (-30 degrees Fahrenheit or below).
โŒ If you have an old vehicle, I wonโ€™t recommend it.
โŒ Little less thick compared to other motor oil.

I have been using this oil for the last 1 Year because it kept my engine from wearing out significantly. But I also used it on an old car and I must say the motor oil didnโ€™t work really well and the engine was looking rusty and dirty.ย 

But when I used it on a comparatively new car, the engine was cleaner. Surprisingly, It also reduced oil sludge and varnish deposits. 

Rust and corrosion protection works well too. I can say it because I have experienced premature wear of critical engine parts such as piston rings, valves and cylinder liners earlier. 

STP 5w-20 is formulated with a proprietary additive package that protects the engine for up to 20000 miles*. 

I will surely recommend this oil if your car is not more than 5 year old. 

This oil utilizes STPโ€™s patented technology to combine outstanding engine performance, protection, and cleanliness with the added benefit of power. So whether youโ€™re looking to improve your carโ€™s fuel economy or just keep it running smoothly, STP 5w-20 has you covered.

It meets ILSAC GF-6 standards to help provide low-speed pre-ignition (LSPI) protection and helps keep engines clean for up to 20,000 miles*.

๐Ÿš— STP 10w30 Pro Formula Motor Oil Review


โœ… It’s also formulated to help keep your engine clean and running smoothly.  
โœ… It offers better cold-start performance and faster oil circulation than conventional motor oils.


โŒ This oil doesn’t mix well with gasoline, resulting in engine problems. 

I have observed high-performance motor oil that has been scientifically formulated to insulate your engine from the damaging effects of wear, because I used to have a used car business. I used STP 10w30 in almost all used cars, because it is cost effective. 

protection against engine wear worked really well even though I used it on old and used cars. This motor oil also has the capability to slightly increase your fuel economy. Only one problem I had sometime, mixing it with gasoline. Not all the time, maybe there were some faulty pieces in the line of product. 

This motor oil is formulated with a unique blend of additives that provide superior protection against wear and tear, while also helping to improve fuel economy. 

STP Pro Formula 5W30 Motor Oil is ideal for use in all types of engines, I have used this oil at high temperatures and heavy loads. This motor oil exceeds all the requirements of all major automotive manufacturers, making it an excellent choice for my vehicle.

๐Ÿš— STP High Mileage Oil Treatment Review


โœ… It can help reduce or prevent leaks.
โœ… Improve the overall performance of the engine.


โŒ It will not solve your leaking or oil consumption problem permanently, it will work more like a bandaid, a temporary solution. 

I was looking for a high-quality oil treatment that can help extend the life of my 2001 Honda Accord, then I tried STP High Mileage Oil Treatment + Stop Leak. This unique formula is designed to help seal and protect engine parts that are prone to leaks, while also improving lubrication and reducing friction.

Well, it worked well for 2 month after applying and you can only add one bottle per oil change. As my Honda Accord is not used often, I had to wait for another oil change to add another bottle to stop leaking. So, I wonโ€™t recommend it for you if you donโ€™t drive too often. 

The oil additive contains ZDDP, which prevents metal-to-metal contact and reduces friction. Well, it serves its purpose in that case. 

The Honda accord engine ran more smoothly and I have experienced less wear on my vehicle’s components. STP High Mileage Oil Treatment is safe for use in both gasoline and diesel engines. But as I mentioned above, it only worked well for 2 months.ย 

Overall, if you’re experiencing leaks and your vehicle is old or has a lot of miles on it and you want a temporary solution then using a high mileage oil treatment stop leak formula may be worth a try. 

Types of Motor Oil

๐Ÿš— SYNTHETIC Engine Oil

Some of the main benefits of synthetic oil include:ย 

  • Reduced friction and wear – This led to improved engine life and performance.
  • Improved fuel economy – Synthetic oils are designed to flow more easily at lower temperatures, which can lead to better fuel economy.
  • Enhanced cold starts – Because they flow more easily at lower temperatures, synthetic oils can help your engine start more smoothly in cold weather.

๐Ÿš— HIGH MILEAGE Engine Oil

High-mileage motor oils are designed for cars with more than 75,000 miles on them. They have special additives that help keep the engine clean and lubricated. This can help reduce wear and tear on the engine and extend its life.

  • Protection against wear and tear.
  • More viscosity for better lubrication.
  • Sealant to prevent leaks.
  • Cleansing agents to remove built-up sludge and deposits.


One key advantage of conventional motor oil is that it comes at a relatively affordable price. In addition, conventional motor oil has a fairly low density, which means it flows readily through your engine โ€“ even in cold weather. This can help minimize start wearing and tear on engine components.

However, there are also some drawbacks to using conventional motor oil. For one thing, it doesn’t last as long as synthetic oil, so you’ll need to change it more frequently. In addition, conventional motor oil can break down at high temperatures, which can lead to engine damage.

Which Type of Motor Oil is Best For You?

There is no one “best” motor oil for everyone since the best type of oil for your car will depend on its make and model, as well as your driving habits. However, most motorists can benefit from using high-quality synthetic motor oil.

Synthetic oils are made from purified natural gas liquids, which means they have a much higher quality than traditional mineral-based oils.

They also have a higher viscosity index, meaning they resist thinning out at high temperatures better than traditional oils. This makes them ideal for use in high-performance or luxury cars that are driven extensively during the summer months.


STP motor oil is a great choice for your car if you can manage those minor cons that come with it. It protects the engine and keeps it running smoothly significantly in my experience. STP has been making quality products for over 50 years. So, you can try it for once at least and see if it suits you.
