Could do without any surprise expenses just before Christmas!
BG44k should be used every 20k or so, on mine it did improve running even consumption, but knowing the injectors and tops of the pistons got a decent clean makes it worthwhile, just for the record Lexus, Bentley etc. put this stuff in at every service......

Always said I would go back to a 6 series
