I plan on changing oil and filter at the 7500 range. Maybe less but prolly around 7500. I'll use an oil extractor for it. Then, the dealer can do the regular 15,000 mile one and since they use the drain, bottom contaminants will be flushed out every 15K or so. However, a year is coming up and I'm still only at 5K so I might have the dealer just change the oil if I can time it right cuz I believe you get a free oil change at either 15K miles or 1 year, whichever comes first.
