So, yes, car manufacturers do exactly this right now. But if you want exact details, or if you have an older MY car you can plug in your own odb-ii reader and download one of the many apps to get those details. My car just threw a CEL and it was because I put low octane gas in. I knew this but also found this by using the handy Forscan app |
