You are stunning ! !<| sep |> We seem to live in a time where any one person making permanent change is very difficult . And , Yes , I ' m talking about politics . There seems to be an inherent stuckness in ideologies and attitudes that should simply not be . <| sep |> I did my first one at around 4 k because of the same reason . There were no metal shavings or specs in the oil when I drained it . I ' ve since corrected to a change at every 3 k but she runs fine , I just like even numbers . Crossed 10 k yesterday and have no problems . <| sep |> That gets you halfway there , because it only measures the hard ones that were saved , not the relatively easy ones that weren ' t . Not sure what you mean . Are you referring to xGA Goals found on American Soccer Analysis ? Because that would include the easy saves that turn into goals by adding a low value for xGA and a higher value to goals .
