After I added the gasoline improver to my tank, I noticed a huge difference! My car ran substantially smoother. I highly recommend everyone gets this product.
Using this product along with the Amsoil oil change is the perfect combination for a great running vehicle.
Bottom Line
Yes, I would recommend this to a friend.

I have been using this PI fuel treatment in all my gasoline engines. From lawnmowers to cars and trucks.
It keeps them running smooth.
My lawnmower was hard to start, and ran rough. I added this. Ran a tank of gas through it while mowing and changed the spark plug afterwards. Runs like a dream now. It sat for months. Started on 2nd pull
I try to use this at least once every 5,000 miles to keep things clean. It seems to work better than other products I've used so I will be sticking with PI.
Bottom Line
Yes, I would recommend this to a friend.

Great for mpg

I put this treatment in my cars tank about 5 or 6 times a year. The engine runs really well and gas mileage has improved over time. The only small problem to me is the plastic seal under the cap. It can be tough to remove.
Bottom Line
Yes, I would recommend this to a friend.

PI fuel injection cleaner

Good product motor runs smooth… if running on long highway travels… it’s helps the cleaner circulate through better..
I have a 2022 BMW with 20,000 miles. I've been noticing the engine has a little stumble now and then at idle at a stop light. I put a whole bottle of this injector cleaner in with a full tank of gas. By the time I'd used a half of a tank of gas the engine idles so smooth that I can't even tell if it's running or not. I look at the tachometer and it's idling very nicely and smooth. This stuff works !!
