Fuel treatments serve as specialized chemicals poured into your car’s tank to carry out a particular refinement function. This may include formulations from cleansers, lubricant and oil, to fuel performance enhancers.

One popular name that can actually be bought not just in auto shops, but also in supermarkets is STP Gas Treatment.

Benefits of Using STP Gas Treatment

With its stabilizing components, STP Gas Treatment enhances your car’s fuel condition by infusing potent cleaning solutions to prevent the formation of deposits such as varnishes, gum, and toxic carbons in your fuel system.

STP Gas Treatment also helps the oil inside the engine keep its natural state, while also avoiding clogging the delicate machine which could be a major contributor of unwanted damage.

Apart from improving your gas-cleaning performance, STP Gas Treatment is also said to enhance fuel quality and efficiency which could help you save money, as it knows how to maintain the fuel injectors and valves right.

How to Use STP Gas Treatment

The STP Gas Treatment is easy to find, and definitely easier to use.

In one usage, it is advisable to have the entire contents of the STP Gas Treatment poured into a tank that’s at least half full. This can actually treat up to 21 gallons of fuel. Another fact is that it can be mixed together with other STP Gas additives, and is considered safe by the manufacturer.

Other Valuable Insights

While STP products tend to prove its credibility, there are still some motorists who prefer to keep their tank rims closed for these fuel additives.

Although they are known to be “keep clean” products, petrol already contains all of the adequate ingredients that your vehicle requires.

For some instances, putting chemicals can also disrupt your gasoline’s chemical equilibrium that may result in damaging your car’s fuel injectors if used inappropriately.

Some drivers opt to put fuel treatments whenever they encounter fuel and engine-related issues, like misfires.

This isn’t a great start – as the first thing you should do is not to buy a fuel treatment, but to identify what causes misfiring. A certified mechanic can help, and he’ll be the one to determine if it’s a new fuel injector, spark plugs, vacuum hoses, or merely a fuel treatment that could fix the problem.

So, before getting the STP Gas Treatment, have your vehicle checked first to know if it really needs it. The product is pretty affordable, yet it could actually make, break, or actually do nothing with your vehicle.

More importantly, when having any chemical product, it is a must to read the label – as the smallest ingredients could possibly lead to the biggest damage that your car could ever have.
