I have a new normally aspirated Subaru, and was going to switch to synthetics, after 2 changes of mineral oil, and ran into the Group 3/synthetic situation. I picked up the Q and 1 on sale to save a few bucks. If the Sube was a turbo, I would go with a full synthetic, but just want a better oil at a more reasonable price. The group 3's sound like a good deal for less extreme motors or driving. I keep my cars a long time but don't put a lot of miles on them, and would like to keep sludge down, and have a better performing oil.
