2005 Mazda 6 i Sport 4dr Sports Sedan (2.3L 4cyl 5M)
Indicated oil consumption of 1 qt /1000 miles, leaves an engine vulnerable when the car design doesn't have an oil light that will illuminate when oil is low. This spells disaster for a car owner. Low end torque minimal, must wind the engine up all a time when starting from a dead stop. This is probably not good for an engine either, especially one constantly consuming oil.
