Same interval with my dealer. With today’s engines and oil formulations, 3k (IMO) is too early, especially for synthetic. I would only do less than 6k if I drove the car really, really hard.I have an 18 Outback 3.6R with about 1600 miles, it says in the manual to change oil at 6000 miles. My dealer says to come in at 3000. It looks like cars101 advises synthetic my dealer is telling me to use Regular???????????

Many would disagree with you. Synthetic allows lower viscosity values to be safely used, and increases fuel economy. It also allows longer service intervals before changing. Why do you think the manufacturers recommend it?Unless you live in Arizona or Alaska (extreme climates) or you use your vehicle in off road conditions or do heavy towing (I mean pulling a 10k lbs trailer)Or marine situation where the motor is running at high RPM for hours. Synthetic is absolutely not needed and there is zero benefit by using it. Don't believe the crap people tell you, do the research. On the other hand, if you do any of the above mentioned things, you would be foolish not to use Synthetic. Synthetic is designed for extreme conditions where regular oil simply is not good enough and would lose its vital properties when pushed to those limit.
A BMW doesn't have a boxer engine where the bottom of the head gasket is sitting in motor oil. The famous Subaru head gasket problem was largely due to gasoline contamination of the oil which ate the head gaskets. The frequent oil changes in a modern Subaru are an attempt to get that contaminated oil out before it causes damage. If you do long highway drives pretty much daily, you're unlikely to have contaminated oil. If you do cold starts and short drives where the engine doesn't fully warm up, you can get gasoline contamination of your oil.The problem I have with the 3.6r oil change intervals is the amount of time, not the mileage. My wife only drives maybe 4k miles in 6 months and never anything close to 6K miles. That means I have to change my oil based on time, not mileage. I only change it to preserve warranty coverage because I know how crazy Subaru gets with oil change intervals. I run syntheric in the 3.6r too. They're also off their rocker with the oil change intervals of 6 months/6K miles on a low revving, naturally aspirated 6 cylinder with a 7 QT oil pan capacity. My 3.0 liter, turbo BMW with 360hp/380tq stock has a 7 quart capacity goes 1 year 10K miles before a change and many have done oil change analysis on the oil and have seen that oil still well within it's service limits. Why would the NA 3.6 be any different? For a company that supposedly cares about the environment, you'd think they'd get on board with a synthetic oil requirement and extending the oil change interval to the industry average.
