Hi Bernardi:

If the erratic oil pressure just started with this cold start then you may have damaged something - hopefully only the sender.

The oil in your car is too heavy for winter use. What the 15W in 15W-40 means is that the cranking speed is equivalent to 15W. That doesn't mean that the oil is equivalent to 15W when cold.

The owners manual for your car specifies 20W down to 10F, so I would put 10WY-30 unless you need that heavy oil for some reason due to mechanical.
