AMSOIL P.i. is a potent gasoline performance improver with concentrated detergent that aggressively cleans stubborn, power-robbing deposits from injectors, valves and the combustion chamber. Effective in port and direct injection systems. Bottle compatible with capless fuel systems. Cleans entire fuel system in one tank of gasoline. For use with cars and trucks. Treats up to 30 gallons. Add entire bottle to tank at fill-up. For best results, clean your fuel system with P.i. every 4,000 miles (6,400 km). Do not use with diesel, E85 or 2-stroke mixed fuel.
Aggressive additives attack the most common forms of engine deposits and limit their effects.
REMOVES FUEL-INJECTOR DEPOSITS
P.i. removes deposits and keeps injectors functioning as they should.
Testing shows P.i. restored GDI fuel injectors to a 100% flow rate after one tank of fuel.2
RESTORES HORSEPOWER
Third-party testing demonstrated performance of P.i. using a 2016 Chevrolet* Silverado* with 100,616 miles on the odometer.
Following a single treatment with P.i., the truck measured an incredible 14% improvement in horsepower.1
CLEANS COMBUSTION CHAMBER DEPOSITS
Fights combustion chamber deposits to help restore power, control knock, increase fuel economy and reduce the need for higher-octane fuels.
Protects against compression loss, difficulty starting and rough idling.
Reduces possibility of "carbon rap," when deposit buildup causes the piston to hit the cylinder head.
Decreases the possibility of pre-ignition "knock" or "pinging."
CAPLESS-COMPATIBLE BOTTLE
Bottle is fully compatible with capless fuel systems.

Sure! Here's a brief example of a review based on a short experience using AMSOIL injector cleaner:
"Recently, I decided to try out the AMSOIL injector cleaner to see if it could improve the performance of my car. I followed the simple application instructions, adding the recommended amount of the cleaner to my fuel tank.
After using it for a few tanks of gas, I did notice a slight improvement in my car's overall performance. The engine seemed to run smoother, and I experienced fewer instances of hesitation or rough idling. Additionally, I noticed a slight improvement in fuel efficiency, which was a pleasant surprise.
One aspect I appreciated about the AMSOIL injector cleaner was its ease of use. The bottle came with clear instructions, and pouring the cleaner into the fuel tank was a hassle-free process.
In conclusion, based on my short experience, I would recommend the AMSOIL injector cleaner. It provided noticeable improvements in engine performance and fuel efficiency. Just be aware of the strong scent it leaves behind. Overall, I found the product to be effective and easy to use."
Remember, this is just a brief example, and you can expand on each point or share more specific details based on your personal experience.
Had a high idle in my 1990 Mazda Miata that performance improver lowered after pouring this into my gas tank. I believe the engine is now running cleaner and stronger. Way better then store bought products like Lucus etc ..
I put this in a 2012 Mercedes GLK 350 that has 120,000 miles. We had loaned this vehicle to the father in law and it did a lot of sitting…often a couple weeks at a time between startups. We got the car back, added a bottle of this magic, and in no time the idle was smooth as new and the car wasn’t downshifting as much on the open road. This is the only time I’ve ever used a fuel additive and actually felt a difference.
Bottom Line
Yes, I would recommend this to a friend.

I have used your synthetic oil for years I just put the new synthetic oil for car with 100,000 miles. I have 2012FordFusion with a 3.0 l V-6 with 97,000 miles and I just put in this new oil and we shall how much the engine will like the new oil. It run like a top and know I will recommend this synthetic foil to any one that wants the engine much longer thanks for the best oil for all gasoline engines
I have always used PI as a preventative solution to combat combustion deposits and a fuel system cleaner. Must be working as I have not had a fuel issue in 15 years.
Bottom Line
Yes, I would recommend this to a friend.
