...For model year 2017, manufacturers recommended premium gasoline for 47.4% of new vehicle model configurations, according to the US Department of Energy (DOE). In model year 1985, premium fuel was recommended for only 6.5% of new vehicle model configurations.

The increased use of turbocharging and higher compression engines that require higher levels of octane contribute to this trend....

I would never buy a car again that takes premium unless it was a HP second car.
Last one I had was in 1991 ( Acura Legend)

New and upcoming engine designs is why GM and other makers wanna do away with 87 octane all together. It's time we progress.

Isn't that a woot when I worked for a pipeline in the seventies this was the story.

Premium gas was 95 octane or higher
Regular gas was 93 to 94 octane
Sub regular (cut rate stations like Time) 92 octane

The gas and todays pricing is a total rip.

^^^^^^^^

Exactly right skyactiv.

Higher compression motors above 10.4 :1 and well above that in more and more motors make it necessary to run higher octane gasoline.

According to the manual my recently purchased 2004 Highlander takes 91 and my 2017 Ram 1500 takes 89. That is the recommended grades. The Honda is the only one that recommends 87.

In addition to high compression , if it has a turbo , that makes a difference , also .

Exactly!

Everything that has a turbo (most new gasoline engines being sold today) should have premium.

Was that research octane, motor octane or the M+R/2 that's displayed on pumps since at least the late 1980s?

And, by CPI inflation... $1.00 in 1980 had the buying power of $3.21 today.

My low compression Nissan 2.5 wont run right on straight 87 - it wants at least one-third 93 OCT SUNOCO in there on top of the EXCELLENT detergent EXxon 87.

here's my idea: Cars & trucks that require premium would have 2 gas tanks, 1 for regular, 1 for premium. The average driver doesn't need to have premium 100% of the time, lets assume 30% as a safe number? If you are currently towing, both tanks could be filled with premium.
Same for track day, or that day you really want to lose your license?

So the total fuel capacity is split with 30% premium and balance is regular. You'd need separate plumbing for the instantaneous use of premium as needed, but that's so easy right :o)

Not all Turbocharged vehicles require premium. The Ecoboosts in the F150 are one example - they are rated on 87 octane, and recommend premium for heavy towing or advanced performance.
