My W124 has the infamous head gasket leak, plus (I'm guessing) some valve guide issues, with the combined effect that I have to add a quart of oil every 700-1000 miles.
I will fix this one day when I can get the car to someone I can trust to do the work correctly (local independent definitely does NOT fit that description), but in the meantime I'm curious...
Do I need to change my oil if I'm refreshing it so frequently? Obviously I would still need to change the filter, but that's an easy no-mess job.
Just a hypothetical question at this point, don't murder me.
