    • Rislone fuel system cleaner 1/12/2024
Size: 16.9 Fl Oz (Pack of 1)
Wow! My 2018 RX 350L was running kind of sluggish and was getting worse. I watched several videos on fuel cleaners and Rislone was always in the top three. It was more expensive than the others by far. But considering replacing the fuel injectors would cost $1000 and probably more for my car I decided to pay the $13. And wow, I could tell the difference in acceleration in the first mile! After 15 miles I had no sluggish acceleration at all. I have only driven 20 miles so far. So I expect the acceleration will get even better. I recommend it and will buy it again. UPDATE 1/22/2024: After driving 175 miles my car runs like new! My car has 53,000 miles on it. This stuff is great. ... show more

    • Great product !!!
Size: 16.9 Fl Oz (Pack of 1)
It does work for a temporary fix. Price wise is very inexpensive against other brand products that are 30 to 40 dollars or even 50 dollars that guarantee passing emission results. If you use this product for every 5 -10 full fuel tank period or more, I can say you can extend your catalytic converter life, a system with a smooth riding & less noise under the hood. If it is every 2 fuel fill up, you will need a new catalytic converter. I have used it on my vehicles the last year and mileage increase has been noted. ... show more

    • Can’t tell the difference
Size: 16.9 Fl Oz (Pack of 1)
Hopefully this stuff is working gas still runs out the same etc. hopefully this prevents future Issues. It’s clean it’s durable and quality is to be determined by ones self. There isn't really a noise difference.

    • Best tune up in a bottle EVER!
Size: 16.9 Fl Oz (Pack of 1)
The mechanic gave my dad a $600 quote to fix his van. I told him to wait a couple week and I put a bottle of this in about half a tank of fuel and in about 4 days his problem of hard start and bad fuel economy was fixed. No, mechanic was not screwing my dad. Mechanic was going to perform the Industry standard repair they were bought to do; change spark plugs and clean injectors. This product removed all the carbon from everything and solved the problem in a cheaper way than the mechanic was willing to do ... show more

    • A little of everything at once
Size: Pack of 4
I'm not sure my car knows what to do with the octane booster but the rest of the additives should help my newer 1.5L tiny turbo stay clean and happy. I'm a little concerned about the summer ethanol mix when the temp here is still below freezing and I expect this should help. It looks and smells like unrefined kerosene. ... show more

    • this is too strong for some cars
Size: 16.9 Fl Oz (Pack of 1)
I put this in my Toyota FJ and now my engine is loud--as in not running smoothly. Toyota said they did not recommend this product, because it's too strong for Toyota sensors.
