Chevron Techron Fuel Injector Cleaner Review

Recently, we’ve looked at some fuel injector cleaners that are available on the market. In this article, we are reviewing the Chevron Techron Concentrate Plus Fuel system cleaner.

The claimed benefits of Techron Concentrate Plus are:

  • Entire fuel system cleaning, from the fuel injectors or carbs to the intake valves and combustion chambers
  • Maximises power, acceleration & fuel economy
  • Reduction of rough idles, surging, lag or hesitation of the engine
  • Improvement of cold start ignition
  • Stabilizes fuel

These promised benefits are typical amongst fuel injector cleaners and as this product is aiming to compete with others on the market, that makes sense.

Why is Techron Fuel Injector Cleaner different to other products?

Chevron officially says that it is intended to be used as a preventative measure against the formation of IDID (internal diesel injector deposits) which can reduce fuel flow and cause poor ignition.

Baked on deposits can reduce power and increase fuel usage, causing sticking of the valves and lower engine compression.

It is suggested that this product is used more frequently than others.

Concentrate Plus Tested

Unlike other injector cleaners, Techron Concentrate Plus has been rigorously tested. Using a variety of 3+-year-old gasoline cars saw an average fuel economy improvement of 8.7%.

When testing diesel vehicles of similar ages, the results evidenced a 7.6% fuel usage decrease. Both fuel types also showed lower CO2 emissions and an improvement in peak power.

Used periodically, those experiments suggest that Concentrate Plus could save the average motorist money.

How long does a treatment last?

The manufacturers claim a treatment will last 6,000 – 10,000 miles or an annual renewal, whichever comes first. Because Concentrate Plus is added to the fuel tank, it is easy to incorporate into scheduled maintenance.

Does Techron Concentrate Plus work?

Almost all reviews of this product online and on YouTube show users testing the product only once, in a reactive manner, rather than a preventative way as per the manufacturer’s instructions.

With that said, the packaging does state that up to 1/3rd of carbon deposits will be removed on the first treatment. We have not seen this clearly in the reviews we observed. It does appear to be a less aggressive substance when compared with products like Sea Foam.

Do you recommend Techron Concentrate Plus?

We suggest that you try a product like Sea Foam instead.

Concentrate Plus is a lot more expensive than Sea Foam, clocking in at around $14+ for 20oz. From the tests we’ve seen, it doesn’t seem to work quite as well.

It also is more complicated to use this product, which must be added to an almost empty gas tank that is then filled to the brim. It’s just not as convenient as other products.

Looking through reviews of this product on Amazon, it appears many people say that it either didn’t do anything or that it caused their fuel usage to drop, even after using multiple bottles of the stuff. Some reviewers recommended using Sea Foam over the Techron solution.

With that said, Chevron are a respected manufacturer and a well established one, they have an outstanding reputation. The conditions above are only what we’ve found, and you may get different results depending on your vehicle, engine, and environment.


A more expensive treatment that is intended to be used as a preventative measure. It doesn’t quite match up with the claims on the packaging or in sales literature and so for that reason; we cannot endorse this product. Instead, we suggest you try Sea Foam.

If you use Techron Concentrate Plus, do let us know below whether it works for you and the results you achieve from treating your fuel.
