My car has had this problem for a while. I changed the oil and oil filter, but it didn't solve anything. As you can see from the photos, when I start the engine, the oil pressure is at 3. After 5 minutes of driving, it's already a little lower, and when the engine warms up, it's at 0, BOTH at idle and while driving.

There are no strange engine noises that would suggest the engine isn't lubricated. The engine oil is in the right amount, halfway between the minimum and maximum marks on the dipstick. I used 10W40 full synthetic oil.

I didn't take it to the mechanic because I need it every day, and since there aren't any strange noises, I don't think there's really no oil getting to the engine. But now I'd like to fix it. What should I check?
