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

Run it every 6000KM - keep the DI injectors nice and clean!

First time user!! After my research I bought AMSOIL gasoline improved for my trucks. I’ve seen huge differences. I use a bottle every 5k when I do my oil changes with AMSOIL oil and filter. I’ve switched all my fluids over to AMSOIL in my trucks. You want the best of the best then buy AMSOIL!!!!

Just put the second bottle in tonight. To early to tell the results however, we will need to wait to see

Never used an injector Cleaner that actually works! That’s including the professional ones like 44K. Blows everything else out of the water.

I had not been using Top Tier gas for sometime and noticed my truck was not running smooth and mileage was down. I added one bottle of Amsoil PI at fill up and after just 1 treatment there was a significant treatment. Since then I have switched to Top Tier gas and add a bottle of Amsoil PI every 3000 miles what a difference!! My truck is a 2011 Toyota Tundra with 287,000 miles and I think I have added another 100k to its life....
