All of a sudden, I am getting an occasional "OIL HI" message. It comes on with a "ding" then may off after a bit....then back on. If I shut down overnight, it stays off unless we drive for an hour or so. An then only on the freeway. Slight up grade.

Changed oil about 600 miles ago.
Level is about 3/4 up the rough section of the dip stick.
Temp is running about 95C
Outside air is 104, A/C running on #3

Everything else seems normal. Is it possible, I am just a tad high on oil and when it gets good and hot there is enough expansion to trip the alarm.

Tks for any input.
