I decided I needed to change the oil. Autozone had the Castrol Tection Extra 15W-40 on sale and the truckers were walking out with tons of it. They only had two gallons left.

It says API CI-4 PLUS, CI-4, CH-4, CG-4, CF-4/SL
Looks like BP owns Castrol now, or maybe always has. Their label is on the bottle now.

Does anyone have an opinion about this oil? I know most folks are Mobile fans.

By the way, I tried some LUCAS heavy duty oil stabilizer and it nearly totally stopped my oil consumption at 263,000miles. I am very impressed with their product. They make extended drain 15W-40 oil, but I have never been able to find it.
