Inconsistencies in gas "brands"

[PANDA]

I have have been putting Shell in my car since the beginning of winter. I filled up at BP and I believe the gas made my tune "off". Previously (last time I scanned/only a week ago.) at WOT car was running 18 deg timing, LTFT's locking in at .08% Commanded 11.7 AFR, and actual was very close to commanded. NO KR. Today car at WOT is locking in at .08% and getting 1-2deg of KR. Actual WB AFR was nowhere near commanded. It leaned out as much as 13.3 in quick WOT pull/scan. I didn't put idle, part throttle, cruise scan data into a graph to see if other areas are off this is just WOT.

I made no changes to the tune, could the gas have done this or is my shit just junk?

gas contains ethanol...if its absorbed moisture even that would throw the tune off

or pump failing lol/filter is clogged

Put a bottle of HEET into the tank and it will remove the water you probably have in it. I actually had the same issue buying gas at the BP on 83 in Mundelein and no issues at the Shell across the street or the Speedway at the next intersection.

Most gas places are letting the tanks go all the way to the bottom and I feel that people have picked up water in their tank far more often.

I vote this, especially since gas went WAY the fuck up last week... dont remember the price, but it jumped at many stations and this wouldnt surprise me

Just add pure sodium to the gasoline, if there's any moisture it will explode. Problem solved.

I've filled up with only 93 V-power for the past 2 years. And 5% back on the Shell Mastercard is FTMFW.
