What do fuel injectors do for your Porsche?

The fuel injectors are responsible for pumping fuel to the engine and at a certain pressure. If the fuel injectors get blocked vehicle performance suffers.

Ask your performance vehicle mechanic if it’s time for an injector cleaner. If you’re a backyard DIYer, you may be able to perform this maintenance task to rid the injectors of dust and debris.

How do you know if it’s time to clean the fuel injectors?

If you’ve driven your Porsche for more than 50,000 miles, it’s probably about time to have this maintenance task performed.

  1. Is your Porsche not performing as well? If so, the problem could be blamed on fuel injector blockage.
  2. You hear an odd, irritating sound when you start your Porsche. You’ll recognize any sounds that are out of the ordinary.
  3. You notice that you aren’t getting as many miles to the gallon as you’re accustomed to.

Your driving habits could be the cause of the need for a fuel injector cleaning. If you:

  1. Drive in cold temperatures
  2. You take a lot of short trips with a lot of stop-and-go-driving

These two conditions can lead to the formation of carbon deposits in the Porsche engine. These deposits dampen the fuel economy and vehicle performance. Today’s fuels can also lead to the buildup of debris in your vehicle’s fuel injectors. The gas we used today is more unstable than in the past and that’s because ethanol is being used as the octane-boosting chemical. The alcohol emulsifies and oxidizes and together they form a noncombustible byproduct and build up in the fuel injectors.

When you use a fuel injector cleaner you’re removing and perhaps eliminating harmful deposits. You should only need to use the fuel additives annually. Thankfully, it is easy to do as all you’re doing is pouring the fuel injector cleaner right into a full gas tank.

Here are a few options for your Porsche’s fuel injector cleaner. When it comes to this it’s not usually vehicle-specific, but you will want to buy the best fuel injector cleaner you can find — you’re caring for your Porsche, after all.
