Here's the OLM data for 2007 Yukon Denali w/6.2L gas engine and for my 2002 Corvette w/5.7L gas engine.

07 Yukon OLM data:

25% remaining after 8100 miles

50% remaining after 6200 miles

35% remaining after 7800 miles

25% remaining after 8600 miles

13% remaining after 10,200 miles

31% remaining after 6750 miles

??% remaining after 8600 miles

39% remaining after 7600 miles

51% remaining after 5100 miles

02 C5 Corvette OLM data:

66% remaining after 5,100 miles

51% remaining after 7,200 miles

27% remaining after 9,300 miles

57% remaining after 5,800 miles

So no more than 5k miles (50%) between changes with the Yukon;

and 10k miles (20%) with the C5.
