Our Mazda 3 has been a rock of reliability up till the dealer accidentally added twice the amount of oil to the car on a routine oil change. My wife drove around the block returned to the dealer in a cloud of blue smoke where they corrected the problem. Our engine leaks and consumes oil 1-2 litres per oil change where as we never had to add oil up to this point. The dealer claims that the oil seal/gaskets are drying up due to the age of the vehicle, causing the leak. Any bright ideas on how the get the dealer to pay the repairs that will be required to the engine?
