Okay, this may be true in parts of the country that don’t experience winter. However, being from the Midwest, the “winter blend” of E85 and 93 are significantly different than the normal blend of fuel and much worse. You really have to be careful in the winter time with fueling.
Would clear premium (92 non ethanol) be a bad idea on a 91 tune? And yes, I have had a bad tank of fuel twice at chevron. Both times I got a tank full of water. It doesn't mean that chervon is bad, just that their tank was running low at the time.
Bringing my B8 SQ5 to South Korea and they claim the Octane rating is 91 for regular and 94 for premium. Do you have more technical data or experience with customers overseas? Last thing I want is knock knock galore after loading up the 93 file.
We'd recommend verifying the fuel rating they use. AKI and RON are different standards. You can always datalog your car to ensure it is running properly as well!
I received a notice from IE yesterday about the release of a product called AutoProtect for the 3.0T B9/9.5 which will lower boost and trigger a CEL if dangerous conditions are detected, namely with cylinder 6. Ironically, poor fuel quality was listed as one of the potential causes of these issues. Any comments on this software or if 034 tunes already have a similar safeguard?
Yes, our tuning already proactively adjusts tuning requests based on if additional knock is detected (which is the sign of poor fuel quality among other potential performance issues).
