Finally got to stretch the guzzler’s legs after a long winter of kid activities.
O2 sensor / fuel sensor and/or a tank of fuel injection cleaner paid off -> saw 15.5 mpg over 200 miles of up and down from prosser to Seattle. With some high winds and 50 miles of wintry mix. Speed limits were 70 or 65 and I was going 5 over. Something worked good and I’m very optimistic that spark plugs and coils will get me into the 16s. Also running a bit better and smoother, though that is hard to prove. For the last couple years I’ve usually seen 13 or 15 (at best) fwy mpg, and never above 12 over hills where downshifting to 4th and 4000 rpm was going on.
Dometic Go system still awesome for water. So convenient and just the right size
New CarPlay portable worked great. I’m going to look for an option with an external microphone to try.
