Down to a 70 cent differential with my local Costco.$4.69 at Costco...
Mine went down 2 cents to $4.159. I'm not liking this new differential. Premium is $4.569.$4.67 at Costco...

$3.80-87,$4.90-D,mobil,,,$3.80-87,$4.60-D,valero
And just as quickly, it is up to $4.199. Somehow $3.19 doesn't sound like much of a gouge.Mine went down 2 cents to $4.159.
