[Hidden Features] STP Synthetic Oil Review

You have the power to help your engine last for a long time by using the right oil quality. Note that the right oil will keep your engine clean, thus increasing its efficiency. You will also get better mileage. There will be no overheating and destruction of engine components hence no risk of dangerous emissions. If you’re still wondering about the right oil to use, here is a complete STP synthetic motor oil review.

Specifications and Approvals

STP synthetic oil meets all the requirements of the proper oil and even exceeds them. One of the main advantages is that it has a long changing interval of 7500-10,000 miles.  It’s affordable and comes in 6pack of 1-quart bottles. It’s a perfect match for both gasoline and diesel engine. The brand comes with three viscosities, namely 5w-20, 5w-30, and 10w-30, to fit in any type of environment.

The market is full of counterfeit goods, and you can’t afford to pick the wrong oil. Note that this is a certified brand since it meets all the requirements of ILSAC GF-5, API SN, not to mention that it also exceeds the previous API standards.


You will understand the benefits well once you know what would happen if you fail to use it. The high friction produced by the engine during the combustion process causes wear and tear of some vital engine components. Rust and other substances may stick on the engine parts, causing an engine knock/stalling. The engine also uses much power, thus consuming more fuel.

Eventually, your pocket will get a severe hit once you start replacing components or even incurring hefty repair costs. Remember, if the exhaust system gets damaged, dangerous emissions may escape to your cabin, thus threatening your life.

That’s where STP synthetic oil comes in handy. It lubricates the engine parts and removes any rust, thus preventing corrosion on the components. The engine will operate smoothly, meaning it will use less fuel.

Chances of wear and tear are highly reduced, thus saving on your running costs. Since the exhaust system is protected, no dangerous emissions will be produced, thus saving your life and environment.

What customers say?

Maybe you’re impressed by the STP synthetic oil review. Before buying the product, it’s good to consider what past buyers think. We have researched on your behalf from different sites, including Amazon, and have compiled the feedback below.

One customer says that he has been using this product for many years, and it has never let him down.

Another one says that she is impressed by the quality of this product and its long-changing intervals. Although she complains that it’s more expensive than conventional oil, she says that the extra coin is worth it.

Yet another customer claims that he was using low-quality oil until his friend introduced him to STP motor oil. At first, he never believed that any oil could have such a long changing interval. Since he started using STP synthetic oil, his trip to the garage has dramatically reduced.

A motor industry expert advises drivers to have regular car maintenance even before exceeding 7,500 miles. He notes that some drivers get a rude shock after ignoring the car for long, only to realize that a minor issue in the engine has highly escalated, and they could have prevented it early.

Should I Switch to STP Motor Oil?

Yes, you should. After all, it’s the perfect oil for all the 4- cycle engines of any capacity. Whether you are dealing with the truck, private car, busses, or even SUVs, STP motor oil remains the best. It meets the proper standards and offers many benefits to your engine.

Never use any type of oil in your car without first consulting the owner’s manual. Note that the oil comes in different viscosities and may harm your engine if you use oil with the wrong viscosity.

Once you read the manual, use the STP motor oil with the right viscosity. Note that the manufacturer in the STP oil recommends that you change the oil every 7,500-10,000miles.

Note that its thermal properties offer excellent protection to the hot engine.

The initials STP stand for the “Scientifically Treated Petroleum” oil.

2. Who makes STP synthetic motor oil?

The STP synthetic oil is manufactured by an American company called Energizer Holdings. This company produces automotive aftermarket products.

This oil also helps the engine to operate efficiently, thus offering you good fuel economy.

Note that some oil in the markets contains corrosive chemicals that harm the internal components of your engine, but STP motors are free from all those chemicals.

4. How long does STP oil treatment last?

When changing the oil, you need to include STP Oil plus STP oil treatment to get a better film. According to the experts, that bond created will protect your engine for over 25,000 miles.

If you want to give your engine better protection, then you need to consider adding synthetic treatment. The treatment prevents oil leaks that result from wear and tear due to excess friction. Treatment comes with a premium seal conditioner helping to repair the seals.

6. Is STP motor oil good for high mileage?

Note that high mileage requires oil with a thick viscosity. So, synthetic oil with a 10w30 viscosity would be better in such an area. However, note that people have complained about the STP oil having an easy flow though not very favorable for the high mileage.

Luckily, you can add STP high mileage oil treatment to offer more protection to your engine.
