I live in Cleveland. It was very cold today. The low 20's. When I went out to my 89 750 after work the low oil pressure warning came on at idle.
If you give it just a little gas it went off. I decided to drive home anyway. I stopped about 15 min into the journey to check the oil level. It was fine. The light did not come on at that point. I have 10w40 in the car. Is that oil too thick and is not flowing at low temp. Has anyone else seen this happen.
