Buying Guide

Oil Additive Buying Guide

If you want to prevent your car or truck from breaking down on the side of the road, it's vital you proactively take steps to keep the engine in good condition at all times. In addition to changing the oil on a regular basis, you should also consider using oil additives that will enhance the performance of your engine, allowing the components to work together as efficiently as possible. Doing so will enhance the life expectancy of any car or truck, enabling you to get the most for your money over the long run. You will, however, notice that different types of additives are on the market, and you must take your time when making your decision to avoid common mistakes and pitfalls. This guide will give you some tips that you will want to consider, and you won't have much trouble finding the perfect product for your vehicle.

Oil Stabilizer

As far as additives are concerned, taking a look at general stabilizers is a good point from which to start your journey. These products will work wonders for reducing the rate at which the engine consumes your oil, but they will also decrease friction. This will help your engine to maintain a safe operating temperature while you travel down the road. You will want to use a stabilizer if your vehicle is in good shape, allowing you to keep it that way for as long as possible. People often add stabilizers during each oil change, and this is a safe rule to follow if you want to achieve a desirable outcome.

High-Mileage Stabilizer

If your car has more than 100,000 miles, a standard stabilizer won't be enough to get the job done. The good news is that you can still opt for stabilizers that are designed for older engines. When you want to keep your car moving, getting a high-mileage additive will protect the gears and other vital parts of your engine. Although this option won't reverse any damage that has already been done, it will go far when it comes to preventing additional harm. Once you know that your vehicle has the type of additive that it needs, you can travel to any destination with confidence.

Leak Treatment

If you have recently noticed dark puddles under your car in the morning or after it has been parked for a while, you have an oil leak that you will want to address. Depending on the size of your leak, replacing the missing oil can get expensive, but that is not even the worst part. Leaks can cause your engine oil to drop to a dangerous level, and this problem can cause irreversible damage to your vehicle. Fixing an oil leak can put a dent in your budget, but you can use an additive that will seal the hole and prevent any more oil from escaping. You will still need to monitor your oil level to ensure that the leak has stopped.

Engine Treatment

No matter how well you take care of your car or truck, grime and sludge will build up over time and decrease your vehicle's performance. When you put an engine treatment solution into your oil, it will quickly get to work cleaning and protecting your engine. It will also create a barrier to reduce heat and to keep your engine running efficiently, and you will likely notice the difference. People are usually amazed when they see what these products can do for them, and you are not likely to disagree when you see the results for yourself.


When it comes to things that can harm your engine, oil oxidation is a threat that you won't want to ignore. The process occurs when oil reaches a high temperature and reacts with the oxygen from the environment. Oxidized oil will become thick and can clog your engine faster than most people would think, and you will be facing expensive repair bills unless you prevent this situation from occurring. You will never be able to stop oxidation, but adding an antioxidant to your oil will slow the process. Using such products is wise for cars that are new and old if your goal is to keep them running well for years to come.

Rust and Corrosion Inhibitors

Even when you use high-quality oil, the metal parts of your engine can still fall victim to rust and corrosion. Most drivers are aware of the problems that corrosion can cause, but they don't know how to safeguard their vehicles from the threat. If you don't settle for anything less than the best, use a dependable corrosion inhibitor, and you will be glad that you did when you see what it can do. By keeping rust away, you will enable your engine to maintain its strength and durability, providing you with a reliable source of transportation.

Final Thoughts

There are many threats that can harm your engine and reduce its reliability and performance, and failing to acknowledge this fact is a mistake that you should never make. Choosing the right oil additive will go a long way when it comes to protecting your engine from trouble. When you want to buy something that will meet your needs, keep the age of your car and the outcome that you would like to achieve at the front of your mind. You will then be able to choose an oil additive with confidence, and you will know that your vehicle won't let you down.
