I had this problem too - as it turns out it came from not using premium gas. The lower octane fuel wasn't providing enough internal combustion, eventually causing the system to overheat about 25 minutes into driving and affecting the oil pressure. I also noticed a bit of jerking when the car switched gears. I thought it was transmission, but it turned out to be combustion related as the fuel was low octane.
