I did go ahead and do the oil change myself with the help of my neighbor and I put in Pennzoil Platinum full synthetic high mileage 5w30 (even though my 03 Subaru only has 46k miles.) This was about a month ago and so far no leaks.
My 08 Element had all of its oil changes at the dealer’s quick lube station, every 5k with 5w20 synthetic blend. Once it was out of the dealer’s 10 year, 100k powertrain warranty (as long as you did oil changes with them). I switched to Pennzoil Ultra Platinum at around 105k miles and have stayed with full synthetic switching around from Pennz to Mobile One and back with no leaks and my Element now has 150k miles.
