My DD Camry 4cyl does get better gas mileage with 93 in the tank. Thought I was crazy but I verified it with a consistent run to a client about 70 miles away over the course of a month.
For 4 weeks straight I needed to go a client up in Wisconsin. I would leave early in the morning to avoid traffic and come back mid afternoon to do the same. I drove consistently at 74 mph (1 under the 10 over rule) with the cruise set. At that speed on that road the car would get 32 to 33 mpg on 87 and 35-36 mpg on 93.
Thinking I was crazy I I switched back on my 4th week and sure enough, right back to 32-33 mpg.
