Do I Need a Fuel Flush?

The fuel system in your car is the way you keep your engine firing correctly, and you keep things in order when it comes to hoses, emissions, and other components and factors. Over time however, your fueling system can really take a toll on the car, which can inadvertently cause a decrease in performance, and overall longevity of main components. If you think you’re having an issue with your car’s performance, fuel may be the issue, and a flush may be necessary. Below are a few things to look out for! 

RPM Issues

Noticing an issue with your RPM’s might seem hard, but it’s much easier than you may think. Because there are traditional revolutions associated with different speeds and torque numbers, your car should be in a fairly routine spot during normal driving. If you begin to see anything out of the ordinary, it may point to a case in which your car isn’t getting the fuel it needs to perform at a high level.

Bad Sounds/MPG

Hearing your engine sound funny typically triggers a yellow check engine light in the bay, however this simply isn’t the case for everyone. If your MPG’s are taking a plunge, or you’ve noticed your engine sound like it’s working harder in order to operate, again, fuel might be an issue that needs checking before going on any drives where it can become more compromised.


A fuel leak can mean holes in your lines, or a backup that’s causing pressure, and a sprung leak in odd places. This may be due to too much sediment in the line, which isn’t a good sign. Additionally, this may mean that there is a higher risk of this sediment making its way into the engine, which could in theory, cause a larger issue. 

Should you feel as if you’re experiencing any issues with your car and you believe it may be related to fuel, bring it somewhere that will take care of properly diagnosing and fixing the issue the first time.
