STP fuel injector cleaner usage frequency
The STP Fuel Injector Cleaner is designed to be used every 3,000 miles or 4,800 kilometres. Deposits can form quickly, even after a vehicle has been driven for as little as 1,000 miles, so regular use of the product is recommended to keep injectors clean and maintain engine performance.
The manufacturer suggests that the entire contents of the bottle should be added to a full tank of gas (50-60 litres or up to 28 gallons) every 3,000 miles. This can be done before or after fuelling, and the product is suitable for all classic and modern engines.
The frequency of use can also be measured in terms of oil changes, with the manufacturer recommending use every oil change or 4,000 miles, whichever comes first. This is because oil breakdown can cause harmful deposits to form in the fuel system, so regular oil changes and the use of a fuel injector cleaner can help prevent this.
It is important to note that the frequency of use may vary depending on driving conditions, engine type, and other factors. For best results, it is recommended to follow the manufacturer's instructions and consult a qualified mechanic for advice specific to your vehicle.
