Any speculation if this is an application-specific issue, something with that station or just an inevitable long-term e85 drawback? Looking into this briefly tonight, its coming up in mostly boosted engines (and mostly dsm’s at that, although that probably has more to do with the widespread e85 usage in that community). Could the cycle of going from boost/higher charge temps to off-boost/cooler charge be bringing crap out of suspension and almost “baking” it to the tips?
FWIW, I did about 2000 miles last year on e85, mostly from the Cumby Farms on 146, injectors were spotless last month when I popped them out of the throttlebodies (obvious NA engine here)
If anyone doesnt want to be bothered with switching tunes this season for the occasional 93/94 tankful, you could experiment with this:http://www.lucasoil.com/products/display_products.sd?iid=335&catid=8&loc=show&headTitle=%20-%20Safeguard%26%238482%3B%20Ethanol%20Fuel%20Conditioner%20with%20Stabilizers
Ive seen pictures of this stuff on quite a few different vehicles, even on cars “built” for e85, with lines tank/fuel cell everything in mind when putting it together still resulting in this black gunk
