A injector flush works well if you have buildup that is affecting your spray pattern. If you don't have a buildup problem then a flush is worthless. You can also have worn pintels (inside the injectors) and if you do the only solution is to replace the injectors. They are not rebuildable.

Techron is still a good cleaner & is probably the only off the shelf one that actually works.

I pour a bottle into 1/4 tank of gas instead of a full tank about 4 times a year. I do this with every vehicle I own.

Listen yourself with a mechanic's stethoscope (Lisle make a good one) or a long screwdriver stuck to your ear. At idle you should clearly hear the "tick" as the valve operates.

Some years ago it was the received wisdom on the list that a bottle of Techron every so often was a Good Action. Haven't heard much about it lately -- I suspect that it's because the fuel companies have finally gotten it together and everyone's gas now has enough of the right detergents in it to avoid injector fouling. But Techron is still around, and I think it's pretty good stuff. Certainly won't hurt (except paying for it) to use a bottle and see what happens.

That's as far as my knowledge goes. But your mechanic's tale sounds just a tad fishy to me.

Yours, David
