Review of STP 78577 Concentrated Fuel Injector Cleaner
The STP 78577 Concentrated Fuel Injector Cleaner will help you save on repairs through its efficient maintenance of your fuel system and engine. Sold in concentrated form, it can dissolve contaminants in or caused by your fuel system so you get a smoother and faster ride.
It will not repair damaged injectors but it can maintain and clean them so you don’t have to go through expensive repairs. From the STP Concentrated Fuel Injector Cleaner, you enjoy better fuel economy and efficiency.
One 5.25 ounce bottle can treat 20 gallons of gasoline (not diesel fuel) but should be used only after 3,000 mile intervals. You cannot use it as frequent as with other fuel cleaners because it is in concentrated form and could damage your fuel line. For older cars with larger gas tanks, you might want to go over the ratio and consider using more.
It is oxygen sensor safe and used by professionals in the vehicle repair and maintenance business. For all vendors of this product, ground shipping only is allowed because of the volatile nature of the ingredients in this product.
Consumers should be warned that this product will not repair damaged parts. If your engine or parts of your fuel system are already compromised, it would better to have them replaced first and then start on a maintenance plan that includes this product.
The STP Concentrated Fuel System Cleaner is an excellent product that comes in small bottles but since it is concentrated, will go a long way. It will improve your fuel efficiency; maintains your engine and fuel system; and works on all gas engines. It is also oxygen sensor safe. In terms of quality and value for money, this is one of the top products you can buy in the market today.
