So you want your injectors cleaned? This product is worth every penny.
The injectors in my Mercruiser 7.4l were gumming up and I was told they needed replacement.
I put two bottles of this stuff in and ran it in the water under load for about 15 minutes and all of a sudden, the boat is running like new. No issues after 10 hours.
I have a T-GDI vehicle and after using this product, I am noticing better acceleration and idling, albeit a very subtle change.
Anything that can help clean injectors is a very good product.
I will continue to use this product every 4000 miles as instructed in the directions for use.
Bottom Line
Yes, I would recommend this to a friend.

I try to use this product every other oil change and I'm amazed that every time it seems to get better MPG. I use it on a Suburban with a 5.3. When I started using the products from Amsoil it would average 14.5 MPG now it averages 15.9 MPG. Still not great but I'll take what I can get.
Bottom Line
Yes, I would recommend this to a friend.

Excellent Product

Been using PI now for several years. In my wife's previous Ford Expedition (2007 5.4L) she did not buy the most quality fuel all the time. Would add PI at every oil change and could actually tell a difference. I use PI in all our current vehicles as well. Not sure I see the MPG increase that it states, but it does help performance.
Bought the truck used. Was operating on f as rm fuel. Was never winter driven and stored in a quonset. 60k Km on odometer. Seemed to be burning a bit rich. Thought I noticed a bit of soot.
After one application of this product I noticed a significant improvement in average fuel economy and the soot issue cleaned right up.
The engine idles smoothly and power and acceleration was improved.
I ran one applications through a 2013 Buick Enclave. Same results. Smoothed out the idle and marked improvement in fuel economy.
I’m happy with this product.

This is the first fuel additive I've used that actually does what it says it will do. Used it in my GMC truck that had hesitation issues and it cleared up the hesitation and skipping after the first bottle.
Bottom Line
Yes, I would recommend this to a friend.
