Rislone 4732 Fuel Injector Cleaner with Upper Cylinder Lubricant, 32 oz

Traveling to FL and added to my RV. I find it hard to explain the great job this product did. Obviously cleaned out crude I didn’t know existed in my vehicle. A marked increase in performance and mileage!

Use this from time to time to keep your baby running smooth. I "juice" my gas tanks up with this by using extra on a low tank of gas then let the car sit either over night or a couple of days. Then take it out and run it hard for 50-60 miles or so then fill the tank. You can feel the difference in the smoothness of the engine as well as easier starts.

Good cleaner but watch the dosage. I put around 4 oz in a 1/2 tank and started getting rough idle and stutter/misfire due to dilution and bad combustion. Once I filled up the tank issues were gone. Just be aware and follow recommended dose.

I'm not brand loyal and usually shop for certain active ingredients to the cost per gallon of fuel doped with fuel additive. This has both PEA and a "Top Lube" that helps keep my Subaru pistons happy. When I purchased a case it was only going to cost about a dollar to treat 15 gallons of fuel at the "normal dose" or around 2.05 USD if the vehicle had a known fuel related issue and needed "double the dosage". It also seemed to fix up a 4 stroke dirt bike one of the neighborhood youngsters was on in a matter of minutes... the motorcycle had trouble idling and would stall after 10 or so feet of riding.. After seeing the design of the frame and engine layout, it would take a little too long to disassemble half the bike to pull the carburetor and properly clean the jets, so he agreed to trying a fuel system cleaner instead. I popped the fuel drain on the carburetor to try and get any sediment out, added an ounce of Rislone to the fuel and topped off the tank with 91 octane ethanol free fuel. Took a few tries to start but finally got it running long enough to spray some Amsoil Power Foam into the running engine. After a few sprays it held a rough idle and let it get up to operating temperature when I sprayed a lot more Power Foam. After the Power Foam burned off he was able to ride down the road out of sight (quarter mile or so) and then out of hearing range so I'm guessing the two Snake Oils did their job and the youngster was able to get back to counting smiles per hour instead of stalls per minute.

I find Rislone products to be a great value and this injector cleaner works well in my 3 cars with various miles. Once a month treatment and my engines run smooth.

Most stuff is snake oil, but if you do the research injectors dry out and become clogged, this is a great conditioner it may not clean but has worked for my small engines and car, trucks just don't overuse it. like any cleaner or additive to much could foul plugs. This will give extra milage for the tank full and notice less sluggishness to acceleration.

So it’s a little more viscous than Lucas fuel treatment and was priced well but after 2 32oz bottles and thousands of miles my mpgs did not improve. The engine appeared to run a bit smoother and acceleration was a bit better but that extra oomph disappeared after the first tank.

good
