Fuel consumption affected by gasoline's Octane number?

With our Navara and X-trail I find that with the way I drive, premium fuel gives better mileage. That may mean nothing because every trip to the pump is different. Road and traffic conditions change so much it's impossible to compare. That's not even counting other factors like weather, elevation, your mood, etc. Only way to really tell is through a controlled test where there are no variables.

For gasoline I fill up with Petron 93 Ron or Shell 95 Ron. For diesel I fill up with Petron Turbodiesel. There's a big difference in how much more fun the cars are to drive vs a small increase in price. I stopped measuring fuel economy a long time ago. Useless with today's traffic.

Oo nga naman.if long drives, i would still prefer hi-octane since iba talaga ang hatak.pero kung traffic, good luck. but here in Davao, traffic isn't much of a problem naman kaya I still prefer using hi-octane since nakakasave naman ako ng about .60 to .70 cents per kilometer. So i wouldn't mind using it everyday since halos same lang naman ang gas expenses ko.
