just noticed this happening in the last week, on sharp left turns at low speed ( under 25 mph) i see the needle drop from 3 to 1.5 than when out of the turn it jumps back to 3. i tested it in right turns and have know problem.
oil level is at the full notch first thing in the morning before start up
using 5w-30 delo, 2000 miles on this oil change


i did a couple of searches but didn't find this happening in other "low oil pressure" questions...
