injector cleaners
 

do any of them work? if so what brand?

besides sending my injectors out for clean and balance ,which is on the to-do pretty soon.

just curious

In my experience nothing that you pour into the gas tank or any on-vehicle servicing will quantitatively do anything positive to the injectors. Only way I recommend is to pull them and send them out for cleaning and flowtesting.

got it. I was just curious. thanks IRP

The real problem is the secondaries tend to be more clogged/weird spray pattern since they only run under full load. You could drive an FD for a very long way without the secondaries coming on once.

Injector cleaners need a tank of gas run through the injectors to clean them up typically. You'd have to full throttle a tank of gas. Not gonna happen.

It's one of those things that are worth doing while you're in there, either if you have to pull the fuel system/rat's nest out or you have the engine out for some reason.

injector cleaners can help but just help and aren't a real solution. for the cost of running 10 tanks of injector cleaner through you might clean them to a degree, but not to the degree you would by sending them for professional cleaning outside the car. cost being the same, labor not included in pulling them nor the time allowing the car to sit, but results will be better.

as long as you keep the fuel system clean to begin with then the injectors will remain clean.

my honda insight had over 300k miles before the injectors started to semi clog and even then only one was roughly 15% off where the other 2 were still perfectly fine. but with a turbo rotary engine, 15% is enough to blow your engine to smithereens.

thank you guys for the replies. I will be pulling them soon to have them sent out for cleaning and tested !

Useing a good brand methanol free fuel will solve most injector problems ! Methanol is engine fuel system killer!!!

no it's not, it however does dislodge all the crap that standard gasoline leaves behind.

most all pump gas has methanol in it, and billions of cars use it everyday.

I us BG44K injector cleaner once a year as regular maintenance. I dont think it will fix clogged injectors, but it will keep clean injectors clean.

oops, i meant ethanol, which is still very similar to methanol.
