Yes back to Auckland. But I topped it up when i got down there.
Topped it up in Auckland -> drove to Palmy -> checked it was down a bit
Filled the fuel tank in Palmy and ran some 'total system cleaner' stuff, also topped up the oil.
Drove back to Auckland -> checked the oil (still hot though) look full.
GF drove it for a week in traffic -> checked it cold down quite a bit -> took about 400-500mls to fill it.
I'm thinking of bringing it to Oil changers for a flush then try a low weight oil. Trying to track down 0w-20 as the manual calls for.
Good info on the amount it shows on the dipstick! thanks for that!
