The Top 3 Turbo Killers

Oil Starvation – to keep your turbo in good condition, you need a constant flow of oil, particularly when the vehicle is driven at high speed. Limited flow of oil can lead to blocked or split pipes.

Oil Contamination – dirty oil or an oil filter that has not been changed can contaminate your engine and can cause abrasive damage to the inside of your turbocharger, reducing its efficiency and causing irreparable damage over time.

Foreign Object Damage – debris and other foreign particles entering your compressor inlet, or the turbine inlet, can also cause damage.

Your driving style– aggressive driving and accelerating hard, for example–may also be a contributing factor. But we’re not kill joys. We love cars and we know you do too. Just ease off every now and again.

How to Spot Turbo Engine Issues

  • Engine warning lights – they’re not just for turbo failure, but can alert you to other issues as well
  • Boost Gauge – if it’s not going up as much as it used to, check it; it might need repair
  • Power loss – if your vehicle is accelerating slower than usual
  • Smoking Exhaust – caused by oil leaking into your exhaust system
  • Whining noise – often a signal of a failing turbocharger

There are a number of actions you can take to help reduce the risk of Turbo Engine failure including changing the oil and oil filter in your vehicle regularly and checking for loose connections or debris. But for a more thorough review, we recommend you get your air filter serviced regularly and get your car serviced annually.
