Buying a new GM truck in the next few months and this will be my first vehicle purchased while new. I don't mind over-doing things but had a question regarding the engine oil. The manual states to perform the first oil change at 7,500 miles. I'm wondering if changing it much sooner, say at 1,000 miles and using a high ZDDP break-in oil would be beneficial? If I did do this would it be detrimental or just a waste of money?
