My post was directed at Spud, not you........& 10w60 is waaaaay too thick a grade oil for our cars.
And yes....im sure Mazda would make handbook recomendations to shorten engine life & increase warranty claims.....NOT....!!!!!!!!!!!!

Ive not blown a car up yet
only a gearbox.. but that was because i was a absolute **** to it...
i change gearbox oil once a year, so thats a bit over 30,000km, or earlier if it consistently doesn't shift as nicely
