Helped me

Used this hoping it would help my rough idle in my jeep and sure enough there has been some improvement. Added 1 can to quarter tank and filled up right after. Next day I changed the oil and within a day or so I started noticing a slight difference in the way it's idling. Not saying it will work miracles but some improvement is better than none!

was having lots of miss fire in my CTS-V over a couple of tanks of gas. I put some of this in on new tank of gas and the misfires were gone.
Passed my California Smog Test

Not 100 percent sure that it helped, but sure didn't hurt. I put it in an empty tank as instructed. Filled up and ran on the entire tank before the smog test. Also ran car at highway speeds for a few days prior to clean out the catalytic converter.

Okay... i have a 2003 Honda Shadow with a gunked up fuel line. I was on 2nd can of seafoam and was all set to send it to the mechanic for a cleaning but, it was so clogged that I was unsure I would make it there. I ordered royal purple on a whim and figured i would try it. After about 10 mins of thinking eh... all of a sudden the line opened up and i had some fun riding around.. There is still some popping coming from the exhaust but, it's less and less with each ride as the stuff works through. Gonna keep at it but, this stuff does well it seems.
this Royal Purple made my car run a whole lot better than what it did before

I got to admit. I thought this product was a bunch of hype. Now that I've used it, I have to eat my words. I don't know about anyone else but, this Royal Purple made my car run a whole lot better than what it did before.
