I usually fill up at Costco but with shell, The torque felt about the same on my 5 speed yaris but my mpg dropped from 34mpg to 30mpg. I tried filling up at different shell stations with the same result. I can maintain about 34mpg with chevron gas but I just can't figure out why my mpg is much less with shell.
The 76 near my house produced the same results as well.

I've used nothing but Shell station gas since I purchased my car two years ago, and I've been averaging 41 MPG combined over that time period.
