Hey guys, I'm new to the whole mustang thing. I have had diesels all my life and always wanted a cobra so now I have a 04 comp orange with 12,000 miles. I love it! Problem is I am a maintenance freak and want the best for my car. Not sure what oil it has now or when it was last changed but I was wanting to know what type oil a oil and why. I know nothing about oil so thanks for the help. The car is in ky, so will be stored in winter and rainy days and will only get about 5 to 7,000 miles a year. I do run the car fairly hard at times and it has a 2.76 pulley,bbk cai, 100mm idler, magnaflow cat back, off road h pipe,and tuned for 93. It made 454/512. Thanks with the help. Great community
