Pretty sure you guys all know Shell have V-power for past month or so. I gave it a try for a month and still am. I noticed my gas milage went up by alot even when i turn on AC for summertime. My last oil service was 2K miles ago and before i'm only getting 270 a tank but after with V-power fuel i'm getting 300-310. Mix driving. Anyone kept an eye on their miles after V-power if u guys used them>?
