My first oil change will be at approximately 1600 miles. My question is, would it be alright for me to use Redline 10w-30w as a FIRST oil change? If so, can I use the factory filter to go along with it, or should I just stick with Mobil 5w-30w? Also, what other filters would you recommend if this oil is o.k. to use? Any suggestions would be appreciated. Thanks.
