If you're using conventional oil then maybe, but these days even conventional oils are so good that every 3000 miles is just a waste of money.change oil every 3000 miles
+1 to this. Just got my UOA result for my current oil with ~3750 miles and it is still performing really well. One thing everyone should know is that the color of the oil does not reflect it's ability to protect and lubricate the engine. Also keep in mind I have a 2011 WRX. They extended oil change intervals up to 7500 miles. I don't see yours being be any different unless your car is still under warranty then follow what is specified on your car manual.If you're using conventional oil then maybe, but these days even conventional oils are so good that every 3000 miles is just a waste of money.
I'd use synthetic oil in a slightly heavier weight than specified by the manual, which I believe is 5w-30. I'd go to a 10w-40 because of the mileage on the car. You can run synthetic oil for easily 7-8k miles without any decrease in reliability. Get a good quality oil filter too, not the cheapo ones. It amazes me how many people stick with crappy oil filters that have much lower filtering capabilities in terms of the particle sizes they'll trap.
That would be very thoughtful and a great service to everyone. Thank you.I'll share the results with you guys.
