The Chevron company most likely needs no introduction. It has over the years gained a reputation as one of the leading companies when it comes to lubricants, refining fuel, and additives. But how good is the company’s Techron fuel injector cleaner?

A good fuel injector cleaner keeps your engine clean and running the way it should. Simply put, it should be able to handle anywhere from minor to major problems that arise from deposits that form on your fuel injectors.

Your fuel injectors are designed to deliver a mist of fuel into your intake. This creates the mixture needed to make your vehicle go. When deposits build up on your fuel injectors, you may experience issues as they begin to malfunction.

While fuel injector cleaner won’t solve every problem, a good one should be able to handle tough deposits. So, does Techron fuel injector cleaner stand up to the challenge?

Why is Techron fuel injector cleaner popular?

Techron fuel injector cleaner is one of the most aggressive products in its niche in the market. It is best suited for vehicles that have begun showing performance issues. Techron fuel injector cleaners have a higher concentration of PEA (polyether amines) than their competitors in the market. If you have some serious trouble with your vehicle, this is the kind of heavy muscle it needs.

The claimed benefits of Techron fuel injector cleaner are:

  • Maximizes your vehicle’s fuel economy, acceleration, and power
  • Entire fuel system cleaning from your intake valves, carbs and combustion chambers
  • Reduces rough idles, engine hesitation and lag

This well-reputed injector cleaning agent functions by cleaning valves, injectors, carburetors, combustion chambers, and the entire fuel management system. Techron fuel injector cleaner will help stabilize your fuel consumption for up to one year quickly acting on impaired injectors. Techron fuel injector cleaner is best used on engines that have missed maintenance for a long time.

Basics of fuel injectors

A fuel injector is a valve that passes on required levels of gasoline into your car’s motor. The levels will depend on the signals it receives. The fuel Injector has a tiny nozzle that your gas pump will send gasoline. It is then transformed into a pressurized mist form when it gets to the manifold. Here it creates a combustion reaction as it mixes with eternal oxygen.  Without fuel injectors, your vehicle’s motor will absorb fuel directly as drops. This not only speeds up your motor wear and tear but also consumes a lot of fuel.

How does Techron fuel injector cleaner work?

Engine combustion normally forms carbon deposits that will build up through your fuel system. These deposits after some time will clog up your vehicle’s fuel injectors, impeding the flow of fuel. If you don’t check your car at this point, it can critically impair your engine’s startup, fuel efficiency, and acceleration.

Techron fuel injector cleaner works by targeting carbon deposits. It breaks them down, clearing them out of your vehicle’s system. This action keeps your vehicle’s engine system clean with continued use. Techron fuel injector cleaner also optimizes the performance of your vehicle, minimizes emissions and maximizes fuel economy and power. According to Chevron, Techron fuel injector helps deliver the best engine efficiency your vehicle can get.

Carbon deposits are common with old cars, and Techron fuel injector probably works better with them. However, as engine technologies are advancing, the operating temperatures are becoming hotter. Also, fuel pressure is increasing. In effect, tolerances are tighter than ever, and fuel injector holes are becoming tinier and more numerous. Therefore, carbon deposits will start developing within the first few thousand miles. You don’t need to panic. Techron insists that they manufacture their Techron fuel injector cleaner to work in both old and modern vehicles.

Chevron is the original developer of both the patented PEA (polyether amines) and PBA (polybutene amine) chemical technologies. They are both used as engine cleaning components. While most commercial products prefer using PBA due to its high efficiency and low costs, PEA is considered as the superior technology. PEA makes engine additives such as Techron fuel injector cleaner expensive. However, Chevron has managed to keep Techron fuel injector cleaner price affordable despite its PEA formula.

Techron products use advanced technology

Techron fuel injector cleaner is as competitive as it is unique. It relies on its main chemical ingredient (PEA) that is a natural non-abrasive substance. Compared with its close competitors in the market, it’s a primal choice since many fuel injector cleaners on the market relay on PBA (polybutene amine). PBA is very effective on a two-stroke and diesel engine, however, it still doesn’t deliver the same amount of benefits.

PBA is also known to cause negative combustion chamber deposits that can damage your vehicle’s fuel injection system and engine. PEA products such as Techron fuel injector cleaner offer added benefits. It will not only improve your vehicle’s startup but also prevent combustion chamber deposit buildups. These build-ups are responsible for spark knocks.
