Made me look.
YTD spending is $3,043 for gas and $2,777 for diesel. For those of us with multiple vehicles and drivers, and where everything is definitely not close, this drop in fuel prices will save us several hundred dollars a year.

Why did I buy a turbo? $2.93 for the required premium fuel. $2.43 for regular.
Are you sure premium is required? Most cars will run on regular, and the engine computer will make adjustments to prevent knocking, with a minor decrease in performance. The manual will usually spell out that premium is recommended (for max performance), but not required.
But if the manual says premium is required, then stick with premium.

The manual says 91 or higher "required". It's about to turn 11 years old so maybe i'll try regular and see what happens. It's not too far from time to trade it in anyway.
Turbos provide additional air into the combustion chamber which will increase pressure and heat and therefore it requires higher octane fuel. If your turbo kicks in, I would not want the engine using lower octane fuel unless you're willing to risk engine damage.
I wonder why diesel hasn't fallen anywhere near as much as gas? Before this all started there tended to be a 10% to 15% premium over gas. These days it's looking like about 30% higher. I think we're still beating most cars with our 45 mpg beetle, but not by as much as usual.
