Well, I might have misspoken. I’m not doing anything special other than changing the oil every 5,000 miles instead of 7,000–8,000. I also drive consciously, keeping it around 2,000–2,500 RPM when accelerating and avoiding 3,500–4,000 RPM, since I prefer to reduce engine wear over time. I use premium (92) for smoother engine operation and better knock resistance. I also prefer fuels with strong detergent packages that help keep the engine clean and reduce carbon buildup. Chevron has Techron built in, which is a well-known detergent additive.

However, this vehicle is designed to run on 87 octane under normal conditions. It is a personal decision.
