Tech Tip: Spot and Solve Common Fuel System Problems

Here’s the truth no matter how you cut it: a vehicle won’t run right if it’s not consistently getting the fuel it needs. Consistency is key, because the gateway to today’s fuel systems are the fuel injectors that open and close in millionths of a second to spray a controlled dose of fuel into the engine. Here are three typical symptoms that indicate a fuel system problem, usually because the fuel injector tolerance is no longer in balance.

  1. Power Loss: Power loss, as well as alternating high and low engine revving and sluggish acceleration, can be a clear sign of fuel injector problems. This is often the result of fuel injectors being clogged or dirty, which impedes fuel delivery.
  2. Misfiring Engine: An engine that misfires may be doing so because the fuel injector valves are not opening or closing correctly, or are leaking fuel. These fuel injector problems are also likely to lead to poor gas mileage performance, poor or rough idling, engine knocking and difficulty starting.
  3. Smoke Emissions: Especially for diesel engines, smoke coming out of the tailpipe, along with general poor engine performance, may be a result of poor-quality fuel which, in turn, clogs fuel injectors.

The solution for these typical fuel injector problems

There are basically two ways to treat these malfunctioning fuel injectors: replace them or clean them. Replacing fuel injectors can be a costly process and is usually not necessary. Cleaning and treating is a much better option. It’s faster, cheaper, and if you use the right solution, very effective. However, not all fuel injector/fuel system treatments are created equal.


There are many fuel injector cleaner products on the market, so it’s best to trust solutions with proven track records and ironclad guarantees. Rislone offers a Complete Gasoline Fuel System Treatment (p/n #4700) and a Complete Diesel Fuel System Treatment (p/n #4740) that not only clean fuel injectors and keep them clean, but can also enhance other aspects of your fuel system that have become dirty due to low-quality fuel, harsh conditions and fuel quality factors.

To clean gasoline engine fuel injectors, simply install Rislone Complete Gasoline Fuel System Treatment into a full tank of fuel. It will eliminate engine noise and engine smoking while simultaneously helping your vehicle use fuel more efficiently. To clean diesel engine fuel injectors, add Rislone Complete Diesel Fuel System Treatment to a tank of fuel. Like the gas counterpart, it will also boost cetane levels, provide anti-gel protection and stabilize the diesel fuel.

We weren’t first to the fuel game, because we realized many of the products on the market did very little in terms of real results, and some didn’t work at all.

We refused to offer a product like that.
