Phase 2. Searching mods to get steadily the best mileage ever

Internet and Google are my friends for a long time. I scoured the web for years when I could afford the time with a super busy professional schedule.

First mod was a K&N air box filter, supposed to let more air flow through the engine (probably in 2000 or 2001): little improvement on mileage, less air restriction?

Then, I went from regular 5w30 oil to synthetic oil same grade, sure improvement on mileage and better car performance (since 2002).

Then, hotter spark plugs to promote more complete gas combustion, little improvement on mileage (around 2005 at first and through 2012)

I did not have enough time to myself to search and find solid evidence to support proposed improvements. From 2000 to 2012, the available money was scarce and I rather learned to control the "nut behind the wheel" and got fairly good mileage.

After retiring in 2012, I got into phase 3
