It’s a cleaner

So no way of tell on my personal vehicle of before and after use without scoping. But I would say it’s a good habit to use a good fuel treatment on occasion to help keep any carbon build up in check.
It's a must for all D.I. engines even with a catch can. I use it about every couple of months seems to work for me. I also use it on my motorcycle, not the whole bottle just what it calls for and no problem. Sure it costs but it works and that's a small price.
Been using this product in all my vehicles never had an issue with any injectors I've logged over 100,000 miles in four different vehicles with this product with never a problem
Have not been able to detect any improvement. Possibly changes are so minimal that it is hard to notice a change. I am not saying that the product is defective but might need some test equipment to pick up a low-lying improvement.
I have been using this for years in all my vehicles. I trust Amsoil to supply me with the best products to protect my vehicles. I have never had an issue with any part of my vehicles that are Amsoil protected.
I have no idea if this did any good in my cars or not. Honestly without tearing down the engine before and after I dont know how you could tell one way or the other. That said, Everything I have used by amsoil has worked very well. Most of it I could actually do the research on and could see the results by those who tested it so I could see the numbers for myself. So Im going to put my trust in amsoil on this and continue to use it with the belief that it does work well. I do know that its the PEA that works in fuel additives and this and redline have the highest concentration of PEA.
Outstanding product to clean fuel injectors!!! It got the job done!!!!
Bottom Line
Yes, I would recommend this to a friend.

Best P.I. Ever

I haven’t even gone through half the tank after filling it up with Amsoil P.I. and I can already notice the difference in the performance of my vehicle. I have a 99 Ford Ranger 2.5l with 275k miles and it is running smoother than ever. There has been a significant improvement in throttle response as well as a significant reduction in pre-ignition knock that occurs when I step on the gas a bit. I will definitely recommend this P.I. to my friends instead of any other brand.
