Royal Purple Max-Clean Fuel System Cleaner and Stabilizer 11722 20 Ounce

Used on my 2016 F-150 200k miles, wasn’t expecting much from a fuel cleaning product, BUT I did notice acceleration improvement. Bought more for wife’s Jeep and father’s Lincoln So YES, I would recommend.

Need a cleaner to clean from fuel tank to exhaust stroke? Boom, here you go. This is a great and strong product to really clean carbon deposits and the fuel system entirely. And protects for future. Easy to use and comes with a little funnel if you don’t have one. Good price and doesn't smell.

This is very good stuff. I was doing a lot of driving and realized my gas mileage had decreased significantly. It was taking 2 tanks from Texas to AZ. My car was sluggish getting on the freeway. I put a can in my tank and filled up. After the first tank driving back to az I put another can and filled up. Drove the second half of the trip. The third fill up which was to begin my trip back to Texas i was accelerating quickly , finding myself doing 100mph, throttle response was excellent. The return trip to Texas i used 1 and a half tanks. 2017 toyota corolla se, 90,000 miles before I ran 2 cans, one after the other. I recommend using a few cans in back to back tanks (one can per tank for most vehicles) and you will see a difference. I follow the directions on the can now and use it every 10,000 miles. My gas mileage is like the day I bought the car new with 32 miles on it.

My family and I have been using Royal Purple Max Clean Synthetic Fuel System Cleaner & Stabilizer for about two years now, and it works great. My brother, who is very mechanically inclined, recommended it to me — and he hasn’t steered me wrong yet! The product itself does exactly what it claims, and we’ve been very happy with the results. My only complaint isn’t about the product, but about Amazon’s shipping. The first bottle I received was missing the funnel that is supposed to come attached, which meant I had to send it back and wait for a replacement. For that inconvenience, I’m giving four stars instead of five. Other than that, this is an excellent product, and I would absolutely recommend it.

I did not look at any of the inside items like the top of the pistons or the valve stems or anything like that but as far as performance, my vehicle which is a 17 suburban 1500 I got better gas mileage, and the engine certainly ran cleaner than it was. Hope some find this review helpful. I also use royal purple oil in several of my vehicles. I certainly like the brand. The product comes with an attachable fill tube, which makes getting it in the fuel tank a lot easier. Note: the deeper your fuel system inlet is the better off you’ll be so you don’t spill.

WORKS GREAT, I PUT IT IN WITH 1/42TANK LEFT DROVE IT AROUND TILL 1/4 TANK FILLED IT UP GAINED 2 MPG

This might be the best of the three top fuel system cleaners I use: Royal Purple made an almost instant improvement in fuel economy and acceleration in two of my vehicles, one an 18 year-old mini-van with nearly 200K miles and the other a newer CUV with almost 100K miles with a turbo. I also use BG44K and Chevron Techron. I always read and was told that Chevron was the "gold standard" in fuel system/fuel injector cleaners, but now I'm not so sure.

A+++ Great stuff. It has PEA which is what you need to clean your fuel injectors. It also has stabilizers to allow you to leave your car for months and still have viable gas when you return. A+++

Pues parece que si funcionó bien, hay muchos productos como este sin embargo si noté que la camioneta recobró cierta potencia. Lo recomiendo

I noticed a more smooth engine performance when I applied the Royal Purple Max-Clean into my fuel. I am still watching out for further improvements as it will take some time to fully realise the benefits.

This product gave me 11% extra mileage but it didn't remove check engine light.
