If you’ve ever parked your car in your driveway only to spot a faint blue haze trailing from the exhaust or found yourself constantly topping off the oil between changes, you’ve experienced the mystery of oil consumption firsthand. It’s a common frustration: why do some cars, like certain Hondas or Toyotas, seem to run for 200,000 miles without needing a drop between changes, while others, like some European performance brands, seem to treat oil like a consumable fluid?
