Hello, I have had a couple people tell me recently that they used too much fuel injector cleaner and it damaged the injectors. Anyone hear of this?

More likely, they had fuel injector problems and those didn't go away by (an attempted fix-in-a-bottle) cleaning.

You should get more specific details from those who stated it.

I've only read of one instance where a leaky injector was attributed to over zealous use of a cleaner (SL-1).

Trav is probably the most qualified to answer this question.

"A couple people?"

I can barely name a couple people who HAD fuel injector problems... let alone several that attribute it to fuel injector cleaner.

Highly unlikely if it's the bottle in tank type, especially if you follow the directions, even if you don't that stuff is very safe for any modern (past 30 years) rubber and plastics.

The most recent person had a Toyota truck and a check engine light came on. Supposedly the shop stated the injectors shorted out because of too much cleaner. The other two people (this was a while ago) were no starts/not getting fuel... All people said they use a bottle almost every tank. I agree and dont feel injectors really are something that fail that often, and the off the shelf cleaners are not aggressive enough to damage an injector. But just thought I would see if anyone else heard of this.

I think I'd ask the show to explain how something in the fuel would cause a short in the electrical part of the injector.

Or maybe it's time for that person to seek out another shop.

Maybe Trav could explain how this could or could not be the case.

The injectors are not shorting out inside from using cleaners, alcohol or anything else. If the person ran a full bottle every tank the concentration keeps getting greater with every tank and at some point the mix doesn't like to light (if its PEA based cleaner), solvent based types like Berrymans, Kreen, etc are not as effected.
SI-1 for example works fine with one full bottle the first use a full bottle every 3-5K or 2-3oz or so every full tank.

Trav may better explain than I but if this electronically controlled fuel injector is of typical construction, one has to ask himself how would PEA or fuel for that matter could ever come in contact with the coils carrying the current pulses?

See "Animated cut through diagram of a typical fuel injector. Click to see animation."
