8,005 mile oil change, oil was in use around 6 months. I’m fairly gentle on my car but I do live in the mountains and I think I’m having a temperature control issue in the engine where it’s running a bit cold(have another post on that) so I’m happy with these results for sure. Was also looking for coolant contamination.
As far as the sub variant of supertech I think I had the “10,000mi” version but I don’t remember offhand. I always buy a full synthetic but don’t always remember if I got the advanced or normal.
Filter wise I just use the Mazda ones. They used to give me the “value” version but the dealer has been handing me the normal one lately. I think it’s the 1-WPE-14-302 in this sample.
