To be honest, i would just change the oil after a year. If you want to see if youre changing the oil too often, send a sample into this place and see what they think

The lab is really the only way to know for sure. Otherwise all we can go off of is what people think is ok...which isn't backed by data. Its just a combination of thoughts that accumulate in everyones minds based on advertising, experiences, things they heard...etc. |
I live in a big city, so most of the time I start up the car I'm looking at about a 20-30 min trip, except a lot of that may be sitting in traffic

I think I'll just go ahead and do it every year.
