Dealer changes the LGT's oil (no charge) every 3000 miles. Recommend getting oil change on the 3.6R or 2.5i no more than 5000 miles. When ever I have gone past that on my 2007 OB 2.5i, the oil seems to break down and it's half to a full quart down. At less than 5K, the oil is still a good color. 7500 is just too long.
This has been a great forum, thanks to all. Happy 4th to each and every Red White and Blue Subie owner!!
