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

I was having vapor-lock and VERY rough running issues with my snowblower. Within one tank problems were solved. I would highly recommend.

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.

This was a decent price on a PEA additive cleaner, where the others do not have the valuable PEA - which is the true cleaner and not just a touch up! The only complaints would be that the cap could more easily close tightly, and it needs a type of funnel cap to pour it in the gas tank on cars. Without it, it makes things tedious where you need gloves, a long funnel and a little bit more time. Other than that, this is best deal I could find.

my car runs smooth

Works great

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.

Cleaned out my fuel injection and still have plenty more I can use in the future

I own a 2010 flex fuel avalanche that was running a bit sluggish even after a tune up I had a mechanic mention this product so I purchased it. I added this to half a tank and ran her on the highway. after 20 miles I started experiencing better acceleration and better mpg truck also idles better.
