Royal Purple Max-Clean Fuel System Cleaner & Stabilizer, 20 fl oz

Worked really well for my Ram 1500. Restored lost performance and fuel economy. Will use once a year. Thank you.

I never received them. Instead, some traing pants for toddlers. It doesn't look like Royal Purple Max fuel stabilizer, 2 cans.

Wow, this actually works! Wife's turbo Sonata was getting a rough idle and a little hesitation on acceleration. No trouble codes found. After reading reviews I took a chance, filled tank and added this Royal Purple. Within 20 miles idle smoothed out, NO Hesitation on acceleration now. Same results on friends and family vehicles. Highly recommended!

Car was idling a little off smooth that I was used to. Decide to add at gas fill up Royal Purple system cleaner. Car after 2 days was back to real smooth running engine. Not to bad a price for what you get. Thanks Walmart for on line purchase and free shipping same day at no additional cost. Better than many online stores especially the big ones and no subscription to get free shipping same day if order early enough. 56

I had been using Lucas upper cylinder lubricant with injector cleaners after reading favorable reviews. It didn't work well for my 2020 Ford Explorer ST as it had developed a pause during acceleration so I tried Royal Purple brand and acceleration has improved significantly. I recommend this product.

After some research, I discovered royal purple's fuel injection System cleaner has the highest level of the best chemical used to clean injectors. Has worked well in our vehicle with direct injection.

keepin my engine with royal purple. with all the crappy gasoline nowadays it pays to throw a can of max clean in the tank occasionally. keep the fuel clean and helps engine performance.

I think this actually did help a bit after two doses (fill-ups) It seems to have helped the engine run smoother and a little more pep. I didn't notice anything after 1 treatment. My car is 10 years old and has about 100,000 miles but no big problems; just wanted to see if a little extra easy cleaning of the fuel system would help. I intend to use fuel treatments every other tank going forward.

If you have an older vehicle that is getting terrible gas mileage this is the miracle fix. I put this in my 200,000 mile car that was down to about 1516 miles to the gallon now I'm getting 18 miles to the gallon. This stuff is amazing. It is the only stuff I tried that cleaned my fuel injectors

Having tried many similar products on the market, I was skeptical about spending money on another lackluster product. But this one did provide noticeable results in my 2008 Maxima. I filled the tank, added the full bottle and took it on the freeway for a few miles of spirited driving. Now the engine has better throttle response.
