Any thoughts about using 91 octane non ethanol gas?

I have been using Shell V-Power exclusively since Day 1.

Last month, I had an issue where the car had to be towed. Turned out to be a bad injector. When chatting with the dealer, they said it might be the gas being used. The SA suggested 'in his personal experience', he would use Chevron Premium, with the Techron already mixed in.

Anybody has any experience of difference between Shell and Chevron premiums? Should I switch, or keep trusting Shell?

I think what the dealer meant was not the brand per se, but the actual gas in that particular time and station (quasi-factory defect). I personally do a monthly switch between Shell V-power and Chevron Premium. My butt dyno tells me Shell gives a little bit more power but Chevron makes the engine run with less vibration overall..

For my 66 fills all were Chevron 91 except for 1 factory german (BP?) fill 1 odd ball United fill 8 Shell 91
Chevron seems to work well ... plus 12oz of Techron super cleanse every 3~5k
