I just started using this in my tacoma it's a 4 cylinder I have to tell you the performance is impressive it says it's good for 4000 miles im on my 2nd tank of gas and my gas mileage improved but the performance is awesome 👌

I run a bottle of PI through at every oil change to help with making sure the injectors in my DI engine are deposit free. The first time I did I could feel the car idling smoother after running through that tank.

Keeps my gdi motor running like new see

I’ve used this on different vehicles I’ve never had a problem with all it says it does. The gas mileage always stayed up.

This product cleans the entire fuel system. It is definitely noticeable. Even my cars idle is smoother. I highly recommend this product every 4,000 miles as directed 👍

Used in my Tahoe the day we left on vacation to the Tennessee Mountains, when we did leave I could noticeably tell a difference in performance and throttle response. At the pumps I was averaging a 1-2mpg gain. With that I would highly recommend.

Well, I've tried just about all of the fuel (Non $3 special Lucas upper ring lubricant additives), aka $$$, and have meager results for the money that was paid. Tried Lucas (Various), Liqui-Moly Fuel Treatment, VP Racing, Chev Techron, Marvel MO (Need to Test More), and Royal P. Only one that made a difference for more than 1 week was MMO, well, until I found this from Amsoil. Not only has this improved my fuel economy, my engines purrs with the injectors being as clean as this got them. Suuuper smooth, restored a lot of lost HP and TQ. I love Amsoil!!!

Just started using, car has low miles. Haven't notice any big changes yet, seriously doubt I gained HP, but? Use with Upper Cylinder Lube. As long as it keeps inside clean it will be well worth it.

After adding and driving a few miles, I noticed my engine went to 4 cyl operation and stayed there for quite a while. The engine seems more responsive and continues to run on 4 cylinder operation more frequently than in the past - better milage.

With product added to my vehicle I’m getting better than manufacturers stated mileage per gallon.

I use every 3 tanks

Made a difference!

J'avais 2 codes "check engine" P0420 & P0430, faisant rapport au catalyseur et oxygen sensor qui se sont effacés après un seul traitement. De mon côté ce fut bénéfique :)

Very noticeable difference in the way my car 2014 ford taurus sho runs with a 2 mpg so far

Great product

Love amilsoil products been running them in all my vehicles for 5+ years!

We tend to keep our cars a long time so this product helps to keep them running smooth.

GREAT PRODUCT! I use it on every fourth fill up. I believe it helps with performance as well as keeping it running smooth and clean.

Great stuff

Noticeable improvement and piece of mind protection.
