Oil (Winter into Spring)
1998 Boxster with 71K miles (purchased from original owner in October 2010).
Did oil change in late October (Mobil1) and have driven the car only on decent days over the last 4 months. Have only put 900 miles on the car since October 2010.
My question is how much longer can I go before changing the oil again? Is it a mileage question or number of months?
thanks,
Dave
