Default Techron harmful to injectors??

Took my 98 C5 (31k on the clock) to the dealership for intermittent hard starting.
Mechanic found 2 leaky injectors (5&6).
The mechanic had asked if I had used any additives...I replied with yes, used Techron twice in the last 6k miles to correct my gas gauge problem (which it had). Mech. suggested Techron may be at fault for
the bad injectors.
Just wondering if there is any truth to this theory, since many forum members here use this additive w/out any issue?

Thanks in advance for your replies.

I put a bottle in the 34 gallon tank on my GMC dually, and it made my " service engine soon " light come on and stay on for two more tanks full. Must have some powerful ingridents. One bottle in our 18 gallon tank would be twice as concentrated.

In fact GM actually uses techron in their fuel system treatment (part#88861011) and recommends using it on a regular basis. I would have to say that if it was bad for the injectors GM would not use it. The label even reads: "removes deposites from injectors which can restrict fuel flow and cause improper fuel injector operation."

That's what I said.
Mech seems to think techron is more for coating than it is for cleaning.
I tend to disagree.

There are a lot of people here using Techron regularly in their cars and I've not heard of a single case of injector failure caused by it.

I'll be the first one to call

I use Chevron gas exclusively and have used Techron without injector problems. Find another mechanic.

Ask him if this is his "theory", or if he has hard data to back it up?

I think you just need to take it out and run the crap out of it at WOT for a while.

Tell him to read the bottle and see if he still thinks the same thing. I'm sure they have a few on their shelves.

I'm a fan of Techron, and use it a lot - but not in the Vette.
I figure I get enough in the Chevron fuel.

But, I do remember reading somewhere about it not being recommended for the Vette injectors. I wonder if it was on this forum?
You might do a search. But as you guys said, lots of us use it all the time.

One ancedote; on my Mercedes forum one of the guys put an additive, (not Techron, BG I think) in his CIS-injected engine, and clogged the tiny injector filter screen with debris that the additive broke loose.

There was an issue with it removing insulation on the L-98 injectors, but it resulted in an electrical problem. Haven't heard of this since.
