I just bought two 2.5 gallon containers of 15-40 Amsoil and Amsoil filters for storage until my truck's oil change light comes on to change out my first oil change. I live in deep south Texas where it is always hot and never goes below 0 degrees. Should I stick with 15-40 instead of 5-40 due to where I live?
When would be a good idea to do my first oil change? Bully Dog techs says to wait till about 6,000 miles or wait till the oil change light comes on??????Thanks.
