Full day on the son's '16 LT Limited 3.6: Changed oil/filter, atf, tire rotation/psi check, ps fluid, brake fluid, cabin air filter, engine air filter, coolant, wiper blades/fluid and spark plugs. Plugs took ~45min. following the great instr. on the forum. No intake removal. Only mildly challenging plug was the drivers rear, but using different sp. plug socket and ext. lengths, got 'er dun, lol!
Changed the engine air filter. Noticed a bit of oil on the intake, but according to my search on here, this is not abnormal. Also noticed my oil was a little low even though I just changed it 6 weeks (2,000 miles) ago. Hopefully not the start of a trend as it has never dropped oil level before. My 2016 LT Limited now has 72,000 miles on it.
