2020 Santa Fe Limited 2.0T Awd
Yep. Same here. Long highway drives hasn't really done much to burn off excess fuel. I did 1.5 hour highway drive yesterday and levels are still about the same.My travel time to work is typical 30-45mins, 75% of that is on hwy but half of that is slow speed with congestion. Similar dilution level in winter and summer, although there is 0.25L less in summer than in winter but I only measured that once and not sure if it is consistent. As far as burning the fuel off when engine heats up + longer drive, it is not happening on my 2.0T.
