    I occasionally have access to E98. My car is tuned for E85 by 04sleeper. Does a E98 blend or full tank provide me with any additional safety when combined with my E85 tune or will this just lead to it running a compromised A/F ratio? I'll likely do an E98 tune, but I have to straighten a few other items out first.

    Thanks!

    You'll go lean on E98, if tuned on e85.

    You'd be ok and rich if you went with E70

    I was concerned about the quality of the ethanol dropping during the fall. I do have a tester kit on order, I'll mix in E98 as needed to keep it close to E85.

    Thanks!

    You are fine. Even on E70 it will be fine. No need to mix anything.
