It may change tomorrow, but it seems like my '06 Accord non-hybrid V-6 has taken a liking to Shell's V-Power gas. On my old '05 Accord V-6 Hybrid, the car ran great on it "for a while". But after so many miles, V-Power seemed to be no more zippy than the medium grade Shell. Seemed flat. Maybe it's possible the plain V-6's do better on V-Power than the hybrid 6's? Possible I guess. Time will tell and changes of seasons, temperatures, barometer I guess, but so far, it's running like a V-8 in this 100 plus degree Texas heat.
