Anyone who owns a car has probably seen commercials for engine oil additives that improve engine performance and protect against wear and tear. But do these products work? In this blog post, we'll take a close look at engine oil additives and discuss whether or not they're worth your hard-earned money.
What are Engine Oil Additives?
Engine oil additives are chemical compounds blended with motor oil to improve an engine's performance. Many can provide enhanced protection between oil changes.
Do I Need Engine Oil Additives?
Not all vehicles need engine additives. If you have a newer vehicle with a warranty, be sure to check the terms of the warranty before using any additive because some manufacturers void the warranty if an additive is used. Some people believe using an additive can cause more problems than it solves, so use caution before adding anything to your motor oil.
Talk to your mechanic to see if he or she thinks an additive is necessary for your vehicle. They will be able to give you specific advice based on your make and model of car as well as your driving habits.
Common Types Of Additives
When it comes to motor oil, various types of oil additives can be used to improve engine performance. Here are some of the more common additives.
Viscosity Modifiers
Viscosity modifiers are added to motor oil to help it flow better in cold weather and maintain its properties at high temperatures.
Dispersants
Dispersants are added to motor oil to keep solid particles suspended in the liquid so they don't settle out and coat engine surfaces.
Rust Inhibitors
Rust & corrosion inhibitors help prevent corrosion by forming a protective film on metal surfaces.
Anti-Wear Agents
Anti-wear additives protect your engine against metal-to-metal contact and friction-induced wear.
The Good, The Bad & The Ugly Side Of Oil Additives
The Good:
Some engine additives can improve your engine's performance and lifespan. For example, products that contain detergents can help keep your engine clean by preventing the build-up of harmful deposits. Other additives, like those that contain friction modifiers, can reduce wear on components and help improve fuel economy.
The Bad:
Not all engine oil additives are created equal. Some products on the market today are little more than snake oil and won't do anything to improve your engine's performance. Some of these products can do more harm than good by clogging up your engine's oil filter or causing other problems. For example, using too many anti-foaming additives can have a reverse effect and increase the production of air bubbles.
The Ugly:
Even some of the best engine additives can only offer limited protection against wear and tear. Over time, all engines will succumb to the ravages of time and mileage. The best way to protect your engine is to change your oil regularly and keep up with scheduled maintenance.
If you're considering using an engine additive in your vehicle to improve your engine life, you must do your homework first. Some of these products can improve your engine's performance, but others are little more than snake oil. Even the best additives can only offer limited wear protection – the best way to protect your engine is to change your oil regularly and keep up with scheduled maintenance at our car service center.
