Fuel Systems Maintenance

What is Automotive Fuel and What Does It Do?

It’s no big mystery that your vehicle runs on fuel, gasoline or diesel; though today more and more are “fuel less cars” in that they run on electricity (but that’s a whole other chapter).

Today’s fuels are a far cry from their earlier predecessors. Fuels today are advanced in terms of how they are refined, how efficiently they burn and the additive package they contain, compared to yesterday’s fuels. Well, to be honest, they’re kind of an amazing work of science. And on top of that, the major oil companies’ fuel products generally contain cleaning agents, detergents and other additives that actually help keep the engine internal parts cleaner, burn more efficiently and run better, longer.

WORD TO THE WISE: DO NOT BUY CHEAP, OFF-BRAND GAS UNLESS YOU ABSOLUETLY HAVE TO (and then only one-off as needed). The reason being, many of the local and national ‘off-brands’ do not contain the quality detergents and fuel enhancing additives that the better fuels contain (hence the cheaper price). Better quality fuels from reputable oil companies, with a good additive package, among other things, should:

  • Reduce injector fouling and valve deposits formation
  • Reduce fuel consumption
  • Offer better power and acceleration
  • Be environmental conservation (reduction of CO2 and other pollutant emissions)
  • Protect vulnerable engine parts (especially against corrosion)


Essentially, the fuel system delivers gasoline or diesel fuel to the engine. The fuel system transfers fuel from the fuel tank, via a fuel pump, and passes it through a fuel filter for straining before it gets sent on to the injectors and into the motor. A pressure regulator controls fuel pressure to ensure good engine performance under a variety of speed and load conditions. The fuel system works with the engine control system to deliver the best performance with the lowest emissions. Fuel injectors, when activated, spray a metered amount of fuel into the engine. Some vehicles use a return line system to return unused fuel back to the tank.

Your vehicle should run at a maximized output and efficiency when the fuel system is maintained and working as it should. When it doesn’t, that’s when a fuel injection (or fuel system) cleaning service comes in.  See your local automotive service center, Pride Auto Care does fuel system services, to properly clean and maintain your vehicle’s fuel system for optimum fuel economy, power and longevity if any of these issues occur:  poor gas mileage, hard starts, ‘CEL” (check engine light) is on, poor drivability.

FYI—Typical Wear and Tear. Intervals for fuel system maintenance may be influenced by:

  • Fuel quality
  • Vehicle age
  • Mileage/time
  • Operating conditions
  • Maintenance history

Warning: Check your car’s fuel system immediately if you smell gas, have issues with starting (can be several components, fuel is one), drivability issues (poor performance or low mileage, etc) or if you suspect the car is driving under-powered.
