E85 quality degradation?
Just filled up at Proper pump an saw "contains minimum 70% of ethanol" sticker on it. Chevron station on Montague in San Jose. 4-5 weeks ago I used Redwood city pump (across Subaru dealership) and saw "minimum 75%" IIRC. That's probably good for flexfuel cars but not if you're tuned specifically for good E85.

There should be no winter blends in CA, I have to say though I test every time for the race car and in fact give the remaining fuel away after each event and when I buy the fuel for the next event I chuck it on the dyno right before leaving and test all 3 maps to make sure.

The 70% minimum ethanol content sticker is not new. It's been on all of the Propel pumps since they started installing them. (Been using Propel for almost 2 years now in my STI)
State mandates that E85 has a minimum 70% ethanol and above content.

Just as a side note, you can get a Zeitronix Ethanol Content Analyzer to see what percentage of ethanol your car is running.

We could definately install those. We were going to use it on a project car but read that the sensors go out relatively often. It would still be a nice gauge to have but I decided against using it to automatically adjust the tune for the Ethanol content.

Installed a bunch, not recommended for 500+ hp setups as they can be a restriction. Very reliable though on lower HP cars all sensors where designed by GM for flex fuel vehicles targeted at 100,000 mile+ service life!
ok... AFAIK GM stopped using this sensor in their flex fuel vehicles because they were failing too often. I could have bad info on this, but I doubt anyone in the aftermarket has been running these for 100k miles.
