Inspection intervals

Hello, my wife is since yesterday proud owner of a Mazda 3 BK 1.6 FLH with automatic. The car is with its 14 years of age still top in shot (only outside 2-3 small traces of usage, but not worth mentioning). The car comes from second hand and was by 2015 by the first owner always check-booked. The second owner (17/18 years, first car) has maintained the car optically so far and also the change of all liquids always durc This is what I would like to do now (let) and ask for your advice, which is exactly what happens now at approx.130000km. Immediately I would have said: Oil change interior filter air filter spark plugs climate maintenance (he has used in between only such a ‘hygiene can’ from Nigrin) Where I am now unsure: transmission oil gasoline / fuel filter The brake fluid was last made 04/2017. vtl. a public “Sheet” of Mazda for the intervals? Thanks in advance and many greetings Marcel
