What Does Motor Oil Do?

Since you already know what gasoline does, let’s cover your motor oil’s job. Your engine’s moving parts create friction, heat, and wear as they operate. Motor oil mitigates these hazards for longer engine life.

So What Do Additives Do?

Fuel and oil additives are chemical compounds that claim to improve performance. They promise added lubrication, minimized wear, cleaner injectors, and other significant benefits. Some additives amount to placebos, and some will do what they claim; however, even the effective ones can cause engine trouble.

Are They Harmful?

So, where’s the harm if an additive does nothing or actually works? Additives can change the chemical properties of what they’re added to, and that’s a problem. You may end up with:

  • Clogged filters
  • Chemical wear
  • Corrosion of key components
  • Cylinder failure
  • And other problems, including the fact that even additives that work can mask deeper issues

How Can I Protect My Engine?

Remember, additives are not a substitute for maintenance. Oil and gasoline are perfectly good at their jobs just as they are.

If you notice a drop in performance or fuel economy, it’s better to address the root cause via maintenance rather than throwing a liquid band-aid on the problem. Your owner’s manual includes the recommended maintenance schedule for your vehicle, which you should follow closely.
