We recently bought a new 2018 GS from Bank St Mazda to replace our old Civic. We’re happy with it so far - service reminder (time interval) just came on at 4 mos., so I came to check the forum for suggestions.
Thanks for the suggestion. Seeing as there's not even 4 000 km on it yet, and the car is only 4 months old, I added another 4 months to the time interval through the infotainment system - I presume the improper interval had been entered by the dealer during prep. I'll take it in at the 8 000 km for the first oil change, though.
I would change the oil early in the break in period. Maybe why the dealer set it to 4000k. Changed my oil the first time after 1000k. You would be surprised on how much metal is in the oil after the first oil change.
