Fuel Injector Cleaning

I was at the dealer today and noticed that they recommend a fuel injector cleaning at 15k and 30k. I started to think back and I've never had my fuel injectors cleaned on any car I have ever had. ( Ist car I think I had with fuel injection was a 1984) I think they want about 100 bucks to do this. I know its a rip off but was just wondering does anyone get this service done and why.

I had a friend who used to work at Jiffy Lube and he said their cleaning system they had actually worked decent. Nothing crazy like 'will make your fuel injectors spray like new' but just enough to notice some gain in gas mileage. And their cost was only like $30. $100 sounds like a complete rip off (well, so does $30 lol)

I've never gotten it done on any of the cars i've had but I do use fuel injection cleaner with every oil change. I use Lucas Fuel Injection Cleaner. It's like $4 a bottle at AutoZone. You pour it in your gas tank at the gas station right before you fill your tank up. Honestly, I don't notice a difference when using it, however, my cars have never experienced any loss in performance or gas mileage throughout the years i've had them.

As for why people do it, for the same reason people don't use cheap gas... to prevent gunk and build up from hampering the spray pattern and flow.
 
I used to use fuel injection cleaner on my 1991 Chevy Cavalier and noticed some difference on power and fuel economy (OK OK, it was a friggin' old engine so needed to keep it alive).

I've used the same thing a couple of times on the 06 MZ5, mostly after being parked idle for 2 weeks or so, just to "purge" the injectors. Haven't noticed a difference though, possibly is just an old custom, along with checking levels every time I travel more than 50 miles :D
 
You'd have to use extraordinarily poor-quality gasoline all the time to need a $100 cleaning every 15,000 miles.
