Dump this in our old cars we'll see what the outcome is

This is the best fuel system cleaner and octane booster I've used. At the price it is offered, it easily competes with all the expensive fuel system cleaners available.

I have used PI for many years. It seems to help my gas milage.

I had about 26000 miles on my vehicle. I put this in my gas tank. I have noticed better gas mileage. Will buy again and put in every oil change.

So it went through a faze where it ran rough ,then bam was smooth & cool running,I guess it had to adjust to additive.otherwise,5 stars from me ..

Great product

Used a bottle at the start of a road trip, and noticed that the car was getting better gas mileage as well as faster response. With the price of gas the way it is, this is a great investment in your vehicle.

This stuff works! I put two ounces (only) in the gas tank of my Harley Davidson's (I own 3, two carbureated and one fuel injected) and within ten-fifteen miles all my bikes seem to react as if I'd freshly tuned them up. Idle is more powerful, throttle response is faster and more potent, top speed comes much quicker with a much stronger feeling of horsepower and torque in the seat of your pants. I love this stuff. PS You only need to use it once every 1,000 miles. You won't regret trying it.

Better performance and mileage…smooth, really smooth

I noticed an immediate improvement in throttle response and idling. Overall, my 2018 GMC Sierra 6.2 runs better. I will definitely use this additive every 4k miles.

Excellent fuel system cleaner.

Works ad advertised

This product gives amazing results and does what it says it will do.

Getting great fuel mileage

Wonderful

2016 f150. Truck runs smoother. Amsoil just make the best. All I can ask is that my truck keeps going, and Amsoil makes sure it does.

Been using this product for the last couple of years in intervals of every 5k to 7500 miles on my car and I always see small increase in fuel mileage and I can feel the engine run a little smoother after every bottle. Cheap way to maintain the engine.

Used this on a road trip at the first fill up and got even more mpg’s.

Helped clean the injectors and get better gas mileage.

First time using the PI Gas Additive in my 4Runner, which has 170k on it, I have used only one bottle and can tell a difference in fuel mileage. I’ll put another bottle in and see what hsppens. So far so good!
