[QUOTE="sdhow, post: 24781, member: 8099"] First...ONLY use synthetic oil. It's what the manufacturers all use now. I always get my first oil change at 500 miles. On a new engine, you have metal particles that are floating around that can cause damage to a new engine, especially on a turbo. Years ago, I got a new truck and I worked for a company that specialized in OE fuel and oil filtration, so I had access to a development lab. Every time someone got a new car or truck, we'd bring it in and do an oil inspection analysis at 500 miles. The oil ALWAYS had fine metal particulates throughout it, from all the newly machined surfaces. After the initial oil change, then every 3-4,000 miles. The reminder light comes on WAAAAAY too late! These are set for 7-7,500 miles. These GDI engines with VVT require clean oil, otherwise don't expect to get much over 100k out of it.
