I use Mobil 1 synthetic and change oil once a year. I drive about 10,000 miles per year in my Z. I send an oil sample to Blackstone Labs for analysis. It always comes back that the oil is essentially as new. There's no coolant, fuel or metal contamination. The analysis only costs $30 and gives me assurance that the oil and engine are in good shape.
