My dad's car, a 1990 Toyota Camry 2.0i, which he bought last summer,
has been running on Mobil 1 5W-50 since he bought it. Then he took the
car to one of his friends, a VW/Audi mechanic to get the oil changed.
They put in some dino juice, and the car started burning oil.. I had
to fill 0.5 liters of oil after 3000 km.. I will change it back to
Mobil 1, this time 0W-40 - we often see temperatures down at -35
degrees Celsius here during winter, but not often over +30 Celsius in
the summer..
