Upon my first use, and by recommendation of Scotty from YouTube, this product made an immediate difference and I thought the car ran fine before. I had used Lucas and Techron for years thinking they were both good products but with fuel changes Scotty was right, a new additive was required and he was right. Felt the difference, saw the difference, could tell the difference immediately.

I used this in my 2016 Grand Cherokee, 2013 Grand Cherokees and 09 Hyundai. This stuff works very well. My 2016 Grand Cherokee gained 3 mpg and the 2013 gained 3.5 mpg. The 09 Hyundai was a friends spare they rarely ever driven so I bought it and tried this first with an oil change using quality synthetic products (oil drained was burnt black conventional), it gained 6 mpg (31mpg)

So AutoZone told me it wasn't going to work because my tank wasn't nearly empty. But I'm not going to let my tank get to nearly empty gas is too high. It took a week or so but my engine light turned off I took my car to get inspected and I passed with flying colors. Thank you so much!!!'

This helps to offset the need of a higher octane gas

After about 3/4 of a full tank I started to notice better response from the truck. Pretty good stuff I say. Looked at my carb and it was spotless. It Removed all deposits and left my carb bright and shiny

I have been using Rislone engine products since I started to drive in 1965. Even then, my old 1955 Chevy Belair ran better and smoother with occasional doses of Rislone fuel system cleaner.

Got this becauae of other reviews.......and it worked...cleaned up a rough idle problem and it did increase mileage, not very much but I will take it.....It also cleared a O2 sensor issue, it was not switching properly and threw a code on a whim......have not seen that code ar a MIL in months! Going to buy more and add every 3,000 miles or so.

I used this product in a 2007 Honda Accord , with a I-4 , VTEC , engine. Miles per gallon had dropped to 23 city 26 highway The car has 247,000 miles on it. I added this to a full tank. I then drove towards Atlanta on I75 75 miles per hour. When I filled up at Half tank left Highway mpg had jumped to 32. Like when the car was new. I improved starting. My main goal was cleaning the fuel injectors. When I returned home I rechecked the car with the computer scan tool. And both long term and short term fuel trims had improved.

Refueled a 2005 Ford Explorer, with 226K miles, and added this product. Historically I've used Techron and now STP, but thought this was worth trying. Even though the Explorer desperately needs its air intake cleaned (KN) and will need an oil change in the near future, a significant improvement in fuel economy has been seen since refueling (about 75 miles driven so far). I would recommend using this for anyone who likes to keep any vehicles well maintained. So far is has proven to be worth the price.

I have had a problem with a rough idle on my 2011 Jeep Liberty with currently only 44k for the last three years and have tried everything mechanical and additives to no avail, but one bottle of Rislone and the idle is now smooth as ice! I am pleasantly shocked as I had all but given up. Give this a try, it's worth the few extra bucks.
