I very rarely leave product reviews, but this one deserves a review. I have 4 vehicles (mine, my wife's, and both of our kids), and 3 of them were bought as used vehicles. So far, I have run 2 bottles through each of the vehicles, and I have noticed a marked improvement in idling, acceleration and gas mileage. My younger son's vehicle had the best improvement. He has a 2018 Subaru, and after 2 bottles of Amsoil he went from getting 18 mpg in the city to getting 22 to 23 mpg in the city, along with much better acceleration and smoother idling. It was getting about 21 to 22 mpg on the highway, but I haven't tested that yet since using Amsoil, although I'm positive it'll be much better now. Additionally, I used 1 bottle, so far, in my mom's 21 year old truck. It idles much better and accelerates much faster and smoother than before. I haven't calculated the gas mileage usage yet, but I'm sure it's better as well. For the past 36 years, I used 2 other very well known fuel additives every oil change, and I did quite a bit of research before buying Amsoil. After the improvements I've seen in 5 different vehicles ranging from 2005 to 2026 year models...I will ONLY use Amsoil every oil change.

Nice product! Its works!

Went from maybe 17 mpg to 18.5 after using this product.

Applied the Amzoil Gasoline PI to a 2015 Subaru Forrester 2.0L Turbo, and after one tank noted a smoother idle and what feels like an increase in power. Very pleased with the product.

This great product also does an amazing job of keeping the ports clean and will prevent the buildup of residue in the engine!

I use P.I. In all of my gas powered equipment. Seems to really work well with keeping things clean and stable.

With the worsening quality of fuels getting delivered these days, to keep your fuel system running clean, and prolong your engine life, use this!

Great product have had zero fuel issues

Great product

I use it once a year. My garage queen sits for extended periods and this product protects and cleans my fuel system for optimal pergormance

I like the performance it gives my engine & will be ordering more soon

I've got to be able to take my Terminal Wife to her appointments or to VA to visit our Son's without problems. I'm not taking chances with my cars. This product has the science and correct ingredients to keep my fuel system clean.

We have a 2014 Lincoln Navigator, and an 08 F150. I've been using this at least twice a year on both trucks. I don't track MPG, but I know that both trucks are running smoother than when we got them. In my mind, this is cheap insurance.

You can see the difference in gas mileage when you use this additive.

No fuel problems and improved gas mileage

Ran PI in my 2016 5.0 f150 on a road trip with 93 borescoped my motor and so much cleaner, then changed my oil Amsoil 5-30 full syn I’m pushing 90 k on the OD and my baby runs clean. All Amsoil products have gotten me to 300 on OD on my fords I’ve owned!!! Freakin great stuff

Legit Street Cars recommended this for any and all fuel system cleaning. I have a HIGHLY modified Audi RS3 on E85 that developed an idle misfire on cylinder 4. Within about ⅓ of a tank, the check engine light was off and has not come back since with 2 full tanks. This is probably the best for cleaning DI injectors out there. Highly satisfied with the additive.

I have seen many ads and have heard many reviews about this product. First time using this product and it has enhanced my vehicle performance.

I added to all three cars with the idea that on DI, the inlet will be clean. I never w degradation - so no idea if it works. I'll give it as a recommendation for now and 4 stars. If I find evidence for improvement, I'll rank this as 5 stars. Cars are two 992.2 3.0L and an Explorer 3.0L.

I use the P.I. every 5k miles in all of my vehicles to keep the fuel system working at peak performance. I know I get the results having pulled the fuel rail off my truck at 162k miles. All the fuel injectors were completely free of any carbon buildup and working like factory new!
