Just as the title says. I put in some Delo XLE 10W30 in my 2005 Outback with a new XG7317 filter, and did not let my wife know about the change. I also dumped the front differential fill of unknown and replaced it with Motul Gear 300. I get home yesterday, and she says, "What did you do to the car yesterday?" I asked why, and she said "the engine was really quiet and the car seemed to drive smoother."
I know it's completely subjective, but my wife never notices anything that I think she should. So I thought it was pretty notable that she actually initiated the conversation about a difference in sound. I already know from personal experience this is a solid oil, along with dustyroads' UOAs from his semi. I'll probably run this out 7500 miles and see what it looks like.
