Midwest Gasoline to Spike $0.50-$1.00 Per gallon

If the Feds are involved it is likely FUBAR.

Yes. In fact, Nuclear FUBAR.

I don't know if I understand this correctly.
Here in Norway it is NOK 21.47 per litre. It will be USD 2.0 per litre.
And the krone exchange rate is 10.71 NOK = 1 USD
So if I am in the US and buy a Gallon, it will cost me NOK 45, or NOK 171 to fix a litre.

Joe is one source of factors impacting gas prices that I have been following for a few years to better understand iong term forces impacting gas prices.

Modern cars have knock sensors. The ignition timing and fuel curves are all based on the feedback of various sensors on the car. If a car is designed to bump up the ignition timing and it detects knock it will dial back the timing, this hurts fuel mileage and power.

The question is will your car pull the timing back running 87 octane. Most of the time no. My 2017 F150 is designed to run on premium fuel and E85 fuel. It will make more power and get better mileage. Same thing with the two Chrysler 5.7 Hemi engines I owned, they are designed for 89 octane.

In my experience the car will not perform better running the higher octane to offset the additional cost of higher octane fuel. Nothing scientific, just seat of the pants.

Of course there are high performance cars that should be running 91 octane or higher.

Regular and prmium gas are the same except for the additive to raise the octane rating. Both have identical BTUs per gallon.
That's been debunked a thousand times.
Premium is meant for turbocharged or high compression engines to prevent detonation.

We learned that in 8th grade drivers training class.

Exactly…

I just typed out way too long a response to this, and then lost it. New engines are almost all "turbo or high compression". Almost every new engine platform will adjust performance based on fuel quality (via knock sensor readings).

I tried it with my '06 Prius. It got worse mileage with Premuim.

Like your oldest said, not tuned for it, no point. My main point is that most new ICE platforms are in fact tuned well enough to notice and adjust for higher knock-resistant fuel.

Just pulled into my local station yesterday... $5.80 for regular gas, $6.80 for diesel. Ouchie

Filled up the 3500HD grocery getter yesterday at the grocery store, for the first time. Diesel price was $3.90, $3.20 after I used my grocery points. Took about $90 for 28 gallons. Just my luck, price dropped today to $3.85.
