The 2010 Tahoe has 10-30 conventional in it, 175,000 miles (5-30 reccommended) Last couple of mornings at minus 10 has taken somewhat longer for the oil pressure to comeup, oil will get changed this week as it is time and will put in 5-30, probably synthetic, usually try to get full synthetic in for winter, just have not gotten it done yet.
