STP diesel injector cleaner is safe for all gasoline engines and cap-less gas systems
The STP diesel injector cleaner is a DIY fuel injector cleaner that contains concentrated detergents that help dissolve and remove harmful carbon, gum, and varnish deposits on fuel injectors. These deposits, if left untreated, can lead to hard starts, lost acceleration, and rough idling. The cleaner is safe for any gasoline engine and is compatible with cap-less gas systems.
The STP diesel injector cleaner is a strong combustible solvent. When added to your gas tank, it helps to break loose and push through any crud between the gas tank's filter and the fuel injectors. This product is safe to use in any gasoline engine, including those with cap-less gas systems.
The STP injector cleaner is designed to be used with an almost empty tank (1/4 full or less). The treat rate for this product is specified on the bottle: a 5.25 fl. oz. bottle treats up to 15 gallons of gasoline, while a 12 fl. oz. bottle treats up to 21 gallons. It is important to follow the instructions on the bottle and use the correct amount for your gas tank size.
While some people find fuel injector cleaners effective, others consider them unnecessary or even a scam, as modern gasolines already contain additives that help clean your engine and combustion chamber.

Use on an almost empty tank (1/4 full or less)
When using STP diesel fuel injector cleaner, it is recommended that you do so when your tank is almost empty (1/4 full or less). This is because the cleaner will be more effective when there is less fuel in the tank to treat.
The STP diesel fuel injector cleaner is designed to be added to your gas tank, where it will break loose and dissolve any crud, carbon, gum, or varnish deposits that have built up between the gas tank's filter and the fuel injectors. These deposits can lead to hard starts, lost acceleration, and rough idling, so the cleaner helps to prevent and fix these issues. By using the cleaner when your tank is almost empty, you ensure that the majority of the fuel being treated is the cleaner itself, which can help to thoroughly clean your fuel injectors and improve engine performance.
It is important to note that while STP diesel fuel injector cleaner can be beneficial, some people consider it unnecessary unless you are experiencing issues with clogged injectors. Additionally, it should be used sparingly, as some solvents can be hard on fuel system components such as rubber gaskets and hoses. Always read the instructions on the bottle and check the MSDS for any strong polar solvents that may be incompatible with your fuel system.
When using the STP diesel fuel injector cleaner with an almost empty tank, simply pour the entire contents of the bottle into your gas tank before refueling. The treat rate will depend on the size of the bottle you have purchased and the capacity of your gas tank, so be sure to check the treat rate specified on the bottle to ensure you are using the correct amount. For example, a 5.25 fl. oz. bottle treats up to 15-21 gallons of gasoline, while a 12 fl. oz. bottle treats up to 21-28 gallons.

Avoid strong polar solvents that are incompatible with rubber and plastics in your fuel system
To use STP diesel fuel injector cleaner, you'll need to add it to your gas tank. This will help to break loose any crud between the gas tank's filter and the fuel injectors, which will then be pushed through the fuel injectors. It is recommended to use this product when your tank is less than a quarter full, and to avoid refilling your tank until it is close to empty.
When using STP diesel fuel injector cleaner, it is important to avoid strong polar solvents that are incompatible with rubber and plastics in your fuel system. Strong polar solvents can attack and dissolve certain plastics and rubbers, causing damage to your fuel system.
The polarity of a solvent refers to its electrical charge, which can be measured on a scale from non-polar to highly polar. Non-polar solvents include paraffin, petrol, and diesel, while highly polar solvents include alcohols and water. In between are moderately polar solvents such as acetone, esters, and chlorinated solvents.
Some common strong polar solvents that should be avoided include turpentine, mineral spirits (paint thinner), linseed oil, lacquer thinner, and methyl alcohol. These solvents can damage materials such as rubber, EPDM, LDPE, HDPE, and polypropylene.
To ensure compatibility and avoid damage, it is important to refer to chemical compatibility charts and consult with experts or product instructions before using any solvent in your fuel system.
