I use this product once a year on my gmc canyon.

Definitely seen a better acceleration response and did notice my gas lasting longer than usual

Help with the idle of my old car

I believe this is my second purchase of this product. I can tell the difference with my acceleration especially when I'm having to pass another vehicle to get around them. It's been a little difficult trying to see if I'm gaining any kind of mileage per gallon of gas because I can't help feeling that acceleration my engine just runs so much smoother I haven't really noticed any any knocking when I start it being at a Dodge Ram 1500 Sport pickup Rams notorious for knocking. I will be sure to use this every 4,000 miles. Thank you Amsoil for another great product.

Put this in my new truck regularly Just to keep it like new inside my fuel injection system I have used this for years without any problems great product

Really didn't see much improvement

My car runs like it's brand new best product.I ever had I will only use Ams oil products

Offer a deep clean !

This is a great product! I can tell it improves gas milage when I use it! I use it when I go on long trips! Definately worth the money!

I used this product and i notcied a difference after one tank full. I will be buying again.

Good product. I use it regularly.

I am driving 273000 mileage Toyota Camry 2005. I used it on 272568. After 25miles of driving now I suddenly feel, there is something happened. Car responses are way far better than a minute ago. Really very appreciative. Amsoil is not available here. No shop sell their products, so additional $10 shipping makes it expensive where the product price is $18. I recommend to buy, but only when it is near around you.

They did a study in Japan on taxi card and wanted to know how they were getting 300,000 + miles out of there engines. It turns out they were adding something similar to Amsoil PI to the tank every 6000 miles which happened quit frequently due to being taxi cabs. So every 4000 miles is reasonable to me. I have only used this once and then bought a case. In my 2025 Subaru 2 4 liter horizontaly opposed turbo boxer I noticed an immediate improvement in torque and smoother running and acceleration. Again cheap insurance dirty injectors cause nightmares.

Absolutely the best top tier fuel additive that actually works. Smooth out rought idle,cleared my rich running check engine light. I don't feel my truck idling at stops. Worth the buy.

Awesome product I noticed a difference on my fuel mpg and performance

Read the product details and tried it on our vehicle within one tank of gas. Our vehicles are running so much better. This is our new go to and it saves so much money and you don’t have to go to a dealership to get your vehicle serviced I will continue to buy this product.

Performance Improver gasoline additive works very well! It helps keep fuel injectors clean!

Great product, love recommending it.

A great product for continued fuel performance

Loving it i can literally see the difference in driving after adding it to the car
