I think it just happened to me also. I have a 2006 Lexus es330, I am aboutat a quarter tank now, I cant wait until it is all out of my engine. My car doesn't run right, I ended up with error codes. I had sears clear the error codes today march 7, 2010 I added it to the car yesterday the 6th, My car was running great. F--------------------------------------------k! What it does is idle bad when I first start the car. The error codes that I got were
PO300 PO303 PO3004 PO3006. I parked the car for about an hour after driving it, it seemed to drive fine, then when I started it, it idle very ruff, I then pushed on the gas peddle to drive it and it drives ok for now.
you can reach me anytime. gbrownresume@yahoo.com if for some reason this site doesn't let me leave my address. the address is gbrownresume at yahoo dot com. I have never had a problem ever with my car, it needs alignment that is about it, now I was hoping that since the car idles ruff, that all I have to do is change the spark plugs, but doesn't sound like that now that I read the other complaints. again you can reach me anytime. I will see what my car is doing tommorow morning when it is cold.

I should have never used the dollar chemical in my car. shaking my head. If you have posted about this already or about to post, leave your information. again contact me anytime gbrownresume at yahoo.com

I have a 2006 BMW 745LI. I use SMB Fuel injector cleaner once every third fill up and it does the opposite to my engine. It runs smoother and gets more gas mileage. Then about 2 months later I read that chevron with techron cleans your engine and injectors. Try to change the gas you use to a better gas company. (Chevron or Shell) Again, I have felt improvement when I used SMB fuel injector. I used it literary over 25 times and sometimes I use 2 bottles...

can any one find a list of the accual ingredients?

Please do not use the smb gas treatment it says it will help your engine they are wrong I put it in my truck and it ran fine before and now it idles rough and it pings this is the worst thing u can put in your car

This product is awful. Put it in my 2002 Durango... now it runs like crap. It was a buck. I wasn't expecting miracles, but I didn't expect it to mess up my truck either. I'm very mad right now!

I also bought a bottle of SMB. I haven't used it yet, and after reading all the neg. comments, I'm not about to. What other brands perform better?
Could it be that other inj. cleaners do the same harm.Anyone out there that is qualified, please suggest a brand.My Vibe is starting to stall at low idle.
May be time to change the plugs. Or is there a good inj. cleaner that works well? Dolph

I use this product on almost every tank of gas I use on this vehicle and the car previous. Both mid line Hyundai make. I find this product to increase horse power ever so slightly and I get easier acceleration and passing on highway. I was very skeptical of the product but for me it has completely replaced the expensive brand I used to use. As I had similar results with a higher price I am very pleased.

Dear Sir
I am wondering if this fuel injector cleaner will work on a diesel engine Cummins 6 cylinder??
