Buyer FAQ. What you Need to Know to Set the Best Deal

What the best fuel system cleaner must have?

There are a lot of multi compatible formulas out there, but you have to stick with the ones that better suit your vehicle. If your fuel is a blend formula, with ethanol and other additives for example, is always good to stick to fuel cleaners that are either highly solvent or quite dedicated to the kind of fuel blend you work with.
Formulas that clean up more than only the fuel system, in other words, cleaners that can bring benefits to engine and other parts of the car are also a must have on the product you are going to buy.

How does the best fuel system cleaner work?

They must be poured into your tank of fuel and preferentially, after filling it completely. This way the formula gets better mixed with the fuel and won’t cause damages since it will be in the correct proportion. In general, only 1 ounce will work for every gallon of fuel and the cleaning formula will work for up to 10k miles. Depending on your car and fuel this number might increase or decrease. Consult the manufacturer of your brand and check any special indications.
