Many variables have been considered and checked. Over the last almost 13 months, I have traveled the same commute 259 times 42.6 miles south to work and 259 times 42.6 miles north to home. 33% of the time south at 6a.m., 33% south at 1p.m., 33% south at 9p.m.. Yes, I have considered.Resist said:
Don't you mean that the knock sensor will adjust the timing for a lower octane? You won't get engine knocking by using a higher octane fuel.Insightful Trekker said:While the Insight's compression ratio is not optimal for 91 octane it does have a knock sensor and will adjust ignition timing to optimize a higher octane fuel (up to a limit).
