Can an Oil Change Cause the Engine Light to Come On?

Whenever you see the dreaded engine light illuminate on your dashboard, it’s natural to experience a surge of anxiety. It’s a warning system that something’s amiss under the hood, but the question remains: what exactly is the cause? Surprisingly, an oil change can sometimes trigger the engine light to switch on, sparking a chain reaction of inquiries.

Engine Light After Oil Change: A Deeper Dive

It’s crucial to understand that an oil change isn’t inherently the culprit behind the engine light. However, here are a few scenarios where an oil change might inadvertently initiate the light’s illumination:

  • Loose oil cap: During an oil change, the oil cap might not be properly tightened, resulting in an oil leak. This loss of oil pressure can trigger the engine light.
  • Damaged oil filter: A damaged or poorly installed oil filter can restrict oil flow and cause the engine light to come on.
  • Overfilled oil: Overfilling the engine with oil can create excessive pressure, leading to the activation of the engine light.
  • Incompatible oil: Using the wrong type of oil for your vehicle can cause engine problems and illuminate the engine light.

Avoiding Engine Light Woes

To minimize the likelihood of the engine light coming on after an oil change, consider these expert recommendations:

  • Check the oil cap: Ensure that the oil cap is securely tightened after the oil change.
  • Inspect the oil filter: Inspect the oil filter for any damage or improper installation.
  • Measure the oil level: Use a dipstick to check the oil level and ensure it’s within the manufacturer’s recommended range.
  • Use the correct oil: Refer to your vehicle’s owner’s manual to determine the appropriate oil type and viscosity for your engine.
  • Regular oil changes: Maintain a regular oil change schedule to prevent the buildup of contaminants and extend engine life.
