My 2017 VW Jetta (5M) OM calls for a spark plug change every 40,000. OEM plugs - IIRC - are DOUBLE platinum.
I note that all kinds of double platinum plugs are showing a much greater change interval.
Why does VW show a much lower (40,000) change interval.
My car is not tuned.
I show no MPG drop - car starts easily - no high (or low) speed missing.
Comments?
