| Re: What is the best synthetic oil? Best oil filter?
The oil change interval is already much shorter on the V, 5000 miles, compared to the 10,000 mile interval for the regular CTS. Interestingly, the recommended oil change for my '05 Porsche GT3 is 2 years or 30,000 miles, no matter how hard you drive it! It too was factory filled with Mobil 1. |
