What's your split between four-wheel drive and pavement driving?

Engine oil: 10K miles with Synthetic 0w20 (lately Quaker State) and Toyota filters purchased by the case on Amazon.
Transmission: 120K miles using Valvoline Synthetic ATF, disconnecting cooler line and using trans to pump out 2 quarts at a time until clear red (about 12 to 14 quarts), but last time on Valvoline it was pretty clear red still. Pull and clean pan and change the filter.
Differentials and transfer case: 50K miles using Mobil Delvac Synthetic 75w90
Yes on factory for all maintenance tasks, though it has been +/- 10K on spark plugs.
90% hwy, 10% off-road 4wd. Wife piles up the miles going between homes in SoCal and Montana (1200 miles). Also, she is an avid geocacher and drives all over, including off-road for that. She is older than me and retired. Myself, I'm still working.
