I think is a good product definitely has my vehicle running a lot better

My car’s 16 years old with almost 150k miles. I was averaging 20.5 ish mpg, i put a full bottle in my tank at fill up and after that tank I’ve been seeing 23-24mpg and my car runs incredible. Would HIGHLY recommend to anyone wanting to treat their car right.

Even though my vehicle takes 91 octane, this treatment improves my gas mileage.

Man this restored the MPG and horsepower in my moms 2010 Camry LE 2.5! It’s made my BMW 428i get better mileage as well and in my other car, 2018 Camry SE, it’s better than the EFI additive they put in at the dealer when they do the service every 5k miles. Paired with the OE 0W-16 oil from AMSOIL as well, I’m getting almost 45 MPG in a petrol car! Amazing results in all my cars and the best fuel cleaner on the market.

Truck runs smoother and mpg’s have improved in the first use of this product!

Your Amsoil gas additive works very well considering a lot of gasolines have a lot of impurities and some water in their gasoline's ! Personally I use higher octane in my gas tank and a name brand gasoline. that way it helps clean fuel injectors stay clean. Your product cleans my fuel injectors and impurities in my engine and I also use a synthetic oil. Thank you Amsoil Gas additive high quality product. I highly recommend this putting in your gas tank at least once a month or every two months. Especially for those people who are on the budget and use regular gas.

Best one ever. Car ran different by improving my horse power, cold starts & gas mileage.

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.
