You report NO noise. No anomalous performance.
How do you define anomalous? from the original post:
While going up the hill on the highway, the car was working harder than usual to get up the hill. It always has since the first day I got the car, but once it got over 45 mph, it flew up the hill. At 50 mph it was still struggling, and that’s when the oil light stayed on for the entire ride.
