Switching from my local Chevron to Mobil has kept it at 1.0 for the past few days, gonna keep my eye on it.
I pretty much exclusively run Chevron because back when I had fuel pump chirp issues, I found Chevron kept the car the quietest. However I have tried a number of different Chevron stations (40 mile commute makes this easy to do) and have seen the same pattern.
