What Is Engine Maintenance?

Engine maintenance refers to routine care and preventive services that ensure your engine runs efficiently and avoids major breakdowns. This includes:

• Oil and filter changes
  
  
• Spark plug and ignition system inspections
  
  
• Timing belt or timing chain service
  
  
• Coolant and fluid checks
  
  
• Air and fuel filter replacement
  
  
• Engine diagnostics and performance testing
  
  
• Valve and cylinder inspections
  
  
• Cleaning of fuel injectors and intake valves
  
  

Skipping routine engine care is like ignoring the “Check Engine” light and hoping for the best. Over time, neglect leads to poor fuel economy, engine knocking, overheating, and costly repairs—even full engine replacements.
