Things To Know About Your Car From Capitol Subaru: Fuel System Maintenance

 

4. Purchase Only Quality Fuel From A Reliable Source

For best performance, make sure you purchase gas only from a reliable filling station. Not that there are many unreliable ones around nowadays. But improperly stored fuel can have debris or water contamination, which could end up in your car and do damage to the fuel system. However, most modern gas stations from major chains won't have such problems. But if you're trying to save a few bucks by getting fuel from a dingy, run-down station with ancient pumps, you might want to reconsider.

 

3. Have The Fuel Filter Replaced Regularly

As part of the routine maintenance guide for your Subaru vehicle, you'll find the recommendation for when to have the fuel filter replaced. What little contaminants that may find their way into your fuel tank are generally picked up by the filter so only pure gasoline makes it to the engine. For example, all 2016 Subaru models should have a new fuel filter installed every 72,000 miles. That means the filter will last quite a long time, but don't forget this important milestone. The fuel filter protects the sensitive fuel injectors from damage.

2. Understand Your EVAP System

Another part of your vehicle's fuel system helps to recapture any gasoline fumes in the tank. It's called the EVAP system. So nothing is wasted, gasoline fumes are directed toward the engine to get burned up. The system also prevents fumes from entering the atmosphere whenever you open up the gas cap and fill the tank. If this system develops problems, you might get a check engine light in the dashboard, or the fuel filler may behave strangely, such as shutting off too soon when refueling. If you're experiencing these problems, a friendly technician in our service center can lend a hand.

 

1. What About Fuel Injector Cleaning?

You may have heard of fuel injector cleaning services, which may promise to enhance fuel economy and restore lost performance. We don't want to recommend this service unless we can point to an actual problem with the fuel injectors. The injectors can become damaged by debris in the gas tank, but the fuel filter should help with much of that. However, the injector nozzle can become clogged with residue over time. A professional injector cleaning can help with this. Fuel system additives won't do much to help fix bad fuel injectors. In some cases, the injectors may simply need to be replaced. But as a rule, your car doesn't need fuel injector cleaning unless a technician says your fuel injectors are badly clogged.

That's why it's great to trust the pros at Capitol with all your auto maintenance needs! We'll diagnose your vehicle properly, so you get all the expert service you need without paying for anything you don't.
