This is complete bs. There is no more energy in a gallon of regular vs premium fuel. This has been tested to death by Consumer Reports and many other non-biased testing labs. A single person's first hand test results is completely meaningless with far too many variables that can alter the results. There are certainly other reasons to use premium fuel and it makes perfect sense to use the fuel type recommended by Lexus but fuel economy is not one of them.

You'll get a minor bump in MPG's but in KY you pay a $1.00 more for 93 vs 87.
The more important advantage comes from the additional fuel additives in the premium fuels.
Shell adds an excellent package.
On long road trips, I'll use Premium on one fill up, and also run Redline Fuel Additive. https://www.redlineoil.com/si-1-comp...system-cleaner
The best Fuel Additives actually work on the valves carbon deposits.
About the only additive that does anything.
