This product is a part of the maintenance regimen for my truck. After 75000 miles, my truck's power and gas mileage has remained consuistent.

Product really works. Purchase a 2020 chevy silverado 2 month ago very low miles runs good added the p.i. and I see the difference right away love it really works

I’m cautious about snake oil in a bottle. However, I’m very impressed with this. Started using it in Allis-Chalmers Antique Tractor, we pull with . Out of the hole, the engine is snappier . And in the light class, I’m able to pull a gear higher. Rarely power out. Just started using it in my ‘18 CT6 Cadillac. These are noted for a problematic 8 speed automatic. Not sure how it’s related, but it’s shifting smoother between gears. Not sure on the MPG improvement yet?

Part of my oil change regiment, when the oil gets changed this gets put in my gas tank. 100% trust any thing amsoil puts there name on !!

I have had excellent results with this product.

I have been using PI for a long time. We have three vehicles that I maintain. I believe it makes a real difference. I recommend PI.

Beware of shady business practices. The product is great but I felt scammed by the business. I ordered a 2 pack and paid $34.88 (about $17 bottle). I later receive and invoice for $20.00 more. When asked, a rep said $20 was for shipping. My total for 2 bottles becomes $54.88. I know pairs about $27 per bottle. Who would pay that much? I felt like they charged me the normal price and after I received the product they sneak in an extra bill. Use caution because I don’t know if they add another charge to your order way after the fact. If they were upfront about the total cost I would have been able to make a better decision on my purchase. Instead, I feel scammed, ripped off, conned, etc.

Have been a Amsoil customer for years, just purchased a new Mazda CX-5 with DPI fuel system just wanted to start the car off with some preventative maintenance A++

I used a bottle of amsoil gasoline in my GMC sierra, and my wife's Buick lacrosse. Ran the tanks until almost empty. I couldn't tell a difference until I refilled the tanks. Let me tell you, all I can say is WOW! They both idled better and definitely had more power! I will be buying more! I highly recommend Amsoil gasoline treatment!

This product did the job! I’ve tried many fuel additives and they’ve never worked. This product cleaned my injectors on the second use!

Amsoil P.I. helps keep your injectors clean, and your engine running smooth! Good stuff!

Super produit je l’adore 😎

This gas treatment is the best in the market I use it 4 different vehicles see the change in more power and more gas mileage i put in my vehicles every 5000 miles

Used as ND could notice improvement in power and milage.. would recommend

Knowing you are doing the best you can to keep it clean and running good. I have seen videos of how good this works so I will keep using.

A must do treatment every 3000 miles. Contains a great PFI chemical with is the best for cleaning carbon and deposits in the fuel injectors. Best to be using top tier fuels and avoid the minimum detergent non top tiers. Additives without the pfi's are snake oil

A thrifty way of life drove me to always seek the cheapest gas prices. My 2019 F150 has a 36 gallon tank. A popular fuel service in my area has Shell colors and at one time had TopTier fuel. They changed. I noticed my fuel efficiency dropped a couple miles per gallon, especially on highway trips at constant speed where I would be expecting better mpg. Truck serviced regularly and no known visible issues that could cause loss of mpg. I used 2 bottles of AmsOil PI in 1 tank, yes, 1 tank, and got better throttle response but most important, now back to expected mpg. As a rule I now only use TopTier fuel and will use PI as maintenance in all my vehicles. Don't be fooled by cheap fuel. It's what you can't see that hurts your engine.

The truck runs smooth with it

Amsoil is always top notch.

best fuel additive on the market
