Sajeev,

With the price of gas dropping to levels not seen in many moons, a thought occurred to me: Many of us are driving around in an average vehicle that has an engine used by another vehicle advertised as having more horsepower and recommending premium fuel.

For example: Toyota’s 3.5-liter V6 powers the Camry and ES350, but the Toyota’s tests with 87 octane fuel while Lexus tests with 91 octane fuel.

Do the manufactures actually bother using different engine programing in these various vehicles? Or is greater horsepower just a premium fill-up away for those with lowlier vehicles with premium antecedents?

I’ve stumbled down a deep and dangerous rabbit hole, and it all started with a jerk nearly hitting me. The jerk in question was driving a tuned SN95 Mustang, swerving in and out of lanes on the interstate without signals, and timed his maneuver around my slow van poorly.

It was hard to stay angry, however, as he dropped a gear and the Modular V-8 snarled enticingly. I drove home and opened up some browser tabs. And more. And more still. As I write, I have twenty tabs open, filled with cars for sale, suspension setup tips, and performance parts catalog houses.

I need help. Or winning lottery numbers. That’d be just as good.
