Just went to Exxon

[Dark Jedi]

while filling up I noticed the 89 is now 88.5 and the 93 is now 92. whats wierd is the 87 stayed 87. anyone else notice this? and is this because of the ethanol being added?

just found it wierd to see the change.

I thought ethanol was supposed to help octane numbers, not hinder them. Did the pump have a sticker saying it contained ethanol? The only time I know for sure I put E10 in my car was when filling up in Arlington. At an Exxon.

on here they say ethanol lowers the octane . and I saw no stickers saying they was using ethanol.
