    My rdx has super clean injectors once again. I will always have this on hand, i promise! I also cant wait to put the One Tank Fuel Cleaner in my ride. I just now need you guys to make synthetic 5w30 and my whole ride will have Hot Shots fluids in it!

    4 out of 5 I do think it works

    I purchased the fuel cleaner the first time and tried it on a 1989 Chev 350 ci engin2 in a pick up used to haul a race car. It seemed to have more pickup and cleaner acceleration under load, so I purchased again for a V6 Sonata with 142k miles. Again an improvement in smooth running at speed after a full tankful plus some. Now going to try in a newer Hyundai turbo engine to see what happens.

    WORKED FOR ME. ROUGH RUNNING 4.7 JEEP GAS. 2004 GRAND CHEROKEE. STARTS AND RUNS MUCH SMOOTHER. MORE POWER. THIS ENGINE HAS STICTION PROBLEMS AND THROWS CAM FOLLOWERS. NO MORE, AFTER TREATING WITH STICTION ELIMINATOR AND PRIMROSE 406. DON’T HAVE TO JUNK IT NOW. NOW TO TRY FR3 ON THE DIFF. CLUTCHES.

    The product made a noticeable difference in the engine performance. Smother idling is most noticeable. Better throttle response, a slight improvement in mpg but better mpg on long distance journeys. It’s better than over products I have used.

    4 out of 5 I am pleased with this

    jimm murray (verified owner)

    I have not trusted any fuel cleaner to work over the years, but decided to try this based on the reputation of the company. I am pleased with the first tank of gas with the “clean out” amount added, it felt like it was slightly surging as I accelerated on the interstates. I am finishing up a second tank of gas with my normal driving around town and am seeing a positive mpg difference. Will now buy more and try our other two cars with it.
