I'll chime in and support the above advice. I probably drive my Crossfire only about 3500 miles a year. So I do the oil changes every 2 years on the car because it sits alot. Synthetic oil is really marketed to extend oil changes and still provide the required protection of today's engines. This really holds true with industrual applications. Any maintenance or plant engineer today knows that using a synthetic will actually reduce costs over time due to superior performance and extended oil changes. If you're planning to perform your oil changes every 3000 miles, the dino oil available today is more than adequate in providing the required protection and at a lower cost. That especially holds true for the typical Detroit V8 designs used in these Cobra applications.
It has always amazed me why folks use synthetic oil and still peform changes every 3000 miles as if it was dino oil being used. I understand the need to do this in cars that are used only for track racing, drag racing, or any other forms of performance driving. But for most of us, that don't buy our cars for that sole purpose, oil changes can be extended to 7500 -10,000 miles with synthetics without suffering any consequences. Even the engine designs from OEM's over the past 10 years, which are becoming more exotic every year, nearly always recommend extended oil change intervals with synthetics.
Enjoy the upcoming warm weather!! Wish I could ride along!!
