Anyone use this stuff? I think you just pour some into your tank (I think) and it is supposed to clean your injectors. I know stuff like ZMax is just a scam but I heard good feedback in regard to Grease Lightning. Any input would be appreciated.

 

I used some when I first bought my car. I can't say I noticed any difference, but at worst it didn't hurt anything. For the $5 or whatever it costs I say go ahead and use it, it's not going to harm anything and it might just help.

 

I have not used the Greased Lighting cleaner. I do use Redline fuel injector cleaner on about a monthly basis. It does seem to help and the price is about $7.50 per bottle, which lasts about 3 months in my case.
