Direct injection engines have changed the automobile industry over the last decade allowing for better combustion and cooler engine temperatures while improving horsepower without sacrificing, or improving, fuel economy. These improved results came with a cost, greater carbon build up on injector tips and intake valves. That cost can be managed by strict adherence to a scheduled maintenance program and understanding what to look for. Warning signs of carbon build up can include:

  • Engine Vibration or not running smoothly
  • Jerking or surging at stops
  • Check Engine Light
  • Misfires

Here are few things you can do to minimize, or eliminate the possibilities of carbon build and possibly avoid a more costly repair later:

  • Oil Changes done regularly with a full synthetic will keep those intake valves performing at their best.
  • Spark Plug Replacement at the recommended mileage because old plugs reduce effectiveness and efficiency of the combustion process.
  • Use Top Tier Gasoline as not all fuel is the same and the higher grades are best for Direct Injection Engines, and stay away from fuels with ethanol additives.
  • Regular Direct Injection Cleaning dissolves hardened fuel deposits on the injector tips and intake valves depending on your make it could be every year or 16,000 miles up to every three years or 30,000 miles. Check maintenance manual for your specific make.
