The Tech included in the TLX is awesome.

My 2015 AWD-SSH Advance is a case in point. But being a geek and a DIY mechanic (had an ASE Cert in the 70's) I like to dig in a bit.

Case in point: Engine Oil Percentage. Is this calculated from mileage & /or time since last change or calculated from the condition of the oil?

If mileage & /or time then is there an entry to reset the Percentage in Vehicle Information that would be different depending on whether one is using 'regular' or synthetic oil? Is there a recommendation from Acura?

Thanks!
