Value For Money

Had an engine light on a Toyota matrix for faulty fuel injector. Put three bottles of this product in my tank and after a thousand kilometers the engine light went away and stayed away. The engine light was on for months and I cleared it several times prior to this so I am confident the product did solve the issue. I have driven about 3000km since the light has gone off and the injector code did not come back. I have not noted a change in fuel economy but maybe a little change.

Worked to remove engine light

Started using this additive from 20  years ago, it works well especially on dirty injectors, even it is not the most powerful injector cleaner in the market, it does the job with lower cost. I used it when I feel car lost some power or just fill in one bottle following car manufacturer's service manual in every 6 months.

Good product with lower cost

Going on a 300km run so put in 2 bottles in a full tank, 115k on the car. After the trip noticed a marked difference, engine quieter, smoother and responsive.

Works as described.

Works great.  A fast, easy and economic way to clean your fuel injector.
My tachometer shows engine RPM goes up and down when the car is idling, a sign of dirty fuel injectors.   The first time it happened I took the car to the dealership and they cleaned the injectors for $200.  Since then I learned to use the STP Injector cleaner that cost me less than $20 to do the same thing.  Now I just add a bottle of cleaner to the gas tank once a year and everything works great.

Works great.

I noticed a slight improvement in fuel economy. No significant performance improvement.

Good product

Can not go wrong.

This stuff works. Car performs better than it ever did. I'm impressed with this product.

STP fuel injection cleaner.

delivery made on the 3rd day instead of next day delivery as advertised. though no big deal, I often wait for this sale as my annual purchase event. thankyou. good deal from walmart .

STP fuel injector cleaner

very poor packaging, the bottles are made of cheap plastic and they fractured while the wrapper was being torn by hand!

low quality product
