Cleaning direct injectors after E85 use
 

Is it recommended to simply replace them as opposed to cleaning?

Local dealerships don't seem to have the necessary tools to do the work. :thumbdown:

If cleaning is alright, any vendor recommendations? New ones are expensive, I have no need for a second set :iono:

Y'all back up and running? I had checked with you earlier in the year and your guy was moving or something.

There are a number of places that can do it. Dr. Injector, Fuel Injector Clinic.

HG performance in San Marco's can do this for you.

Yup, back up and in business!

I ended up using Injector Pulse here in Virginia. For folks in the east, they are a bit closer and they are a NASA Mid-Atlantic sponsor. Quick turnaround time too.

Does having run E85 for a time make it more advisable to do this? I ran it for about 10,000 miles but can't get it here anymore. I'll have my ESC installation finished in a week and plan to stay with 93 octane after that.

what would need to be cleaned after using E85? Its a very clean fuel. what am I missing? I would think that needing cleaning from gasoline is more common as its known to be much dirtier.

What can you tell us about the use of the graphite seals vs reinforced vs OEM? I can't see any physical difference with the reinforced ones from photos. Never met anyone running graphite either? I believe I have one bad seal that's causing a misfire on cylinder one. No matter what Zach does, it's always that cylinder that misfires first and much earlier than others.

btw for anyone reading this, I'd much rather trust CSG to clean and install these than the local subaru dealerships. Local dealership mangled my first set of DI seals and don't do this very often.

OEM is factory.

Graphite is standard by Bosch for all their high-heat and motorsport applications for GDI.

The reinforced are Autofactory seals which are easy to install, stronger, and have a secret sauce that is proprietary to the reinforced seals.

Is running a few tanks of 93 to 'flush' and 'clean' the injectors not enough anymore? I run 93 for 3 months out of the year and that's when it gets cold here in Chicago. I was under the impression that was enough to keep the injectors clean and healthy. I guess not?
