Great product to use in older vehicles or to keep newer vehicles running smoothly. Cleans out the gunk left behind by the ethanol in our fuels. Cheaper than Auto Parts and big blue box store.

I just purchased a used car and when I got it I was experiencing stuttering when accelerating. I thought to get an injector cleaner to try it out and this one popped up. I put it in with 10 gallons of fuel as stated, and the next day I saw a difference in power and throttle response. I will be putting Royal purple in my car every 3,000 miles without question.

Good product, fast shipping

Appears to be a good product and it should work well.

I dumped it in my tank at the highest recommended concentration. After 400km it almost totally cleared up the rough idle which I suspect was clogged injectors.I'm reordering, and intend to use a bottle every tank from now on.(1998 Silverado 5.0L 577,000km)

Unsure why the bottle leaks for some reviews...it's sealed! + a twist top! Used purple fuel system cleaner and it didn't work. Used the injector cleaner, WHOO! Engine came alive! More MPG, more torque and way better performance! I can't say enough good things!

This is really good stuff... I did a separate manual throttle body cleaning myself first and spark plug replacement... used this product to clean out the other fuel system components primarily the injectors... I have a smaller fuel tank in my Mazda3 (14 gallon)... product says use entire package for up to 20 gallon... I place half of the package in my empty tank and put 10 gallons on top... I repeated this exact recipe a second time... during the first treatment using this mix method I could visibly notice thicker exhaust and experience noticeable performance gains... before the end of the second treatment emissions were clean performance was peak and fuel efficiency was renewed to manufacturers specs

i usually use seafoam,, which is great stuff. on a whim i tried royal purple fuel cleaner. good stuff, stabilizes the ethanol in the gasoline and my cars have been idling smoother since using this stuff.

I drive a 2016 Ram 1500 with the 5.7 hemi, the engine started to seem excessively loud at around 133,000km. Within 3 days of driving to work and back the truck was noticeably quieter ok idle and fuel economy improved over 1 liter per 100km. Will definitely be buying again

I drive just under 15 miles each way to and from work. This means I get to travel at 70mph for most of it. In just over a week I have had chance for this to circulate and do what's promised. It does and I'm very happy. It's a shame it's now out of stock, so many more people can't experience this in their own vehicles.

Tengo un Lincoln MKS que de repente dejaba de acelerar y perdía potencia, mi mecánico sugirió un lavado de inyectores y del cuerpo de aceleración, decidí comprar este tratamiento solo por curiosidad, y después de usar este producto por algunos kilómetros, noté mejoría al grado de ya no llevarlo al mecánico, ahora el auto lleva poco más de 2000 km de haber puesto el tratamiento y sigue sin problemas.

I could clearly feel the difference in drivingThanks
