Hey all! New here. We got our 2013 Mazda CX-5 Touring three weeks ago. We bought the 3 year service package and were told synthetic only, change every 7,500 miles and there was no break in oil change. I'm used to doing a change at the first 1,000 miles, but I can happily go every 7,500. I went ever 5,000+ on our old 2005 4cyl Saturn with no issues.
