2014 Mazda CX-5. In 2 weeks I'll be going to Memphis to eat bbq and listen to some blues. By the time I leave,I'll have 3500 miles on the clock. I plan on putting 2000-2500 miles on during the trip. The question is- Do the first oil change before leaving,Get close to 5000 miles and get it changed down there,or leave it till I get home. Like I said,this is the first change on the factory fill. Opinions please!
