2008 3.8L problems
2008 3.8L 20,000 miles consumes a lot of oil, after reading the numerous threads I wouldn't care that much since I could just add oil more often - but there's another issue. There is a knocking noise that's slowly getting worse - it only happens under heavier than normal load (i.e. uphill, highway on-ramp acceleration) and it's not rpm based, sounds like knocking (single rock in a coffee can) not lifter tick. I've switched to 5W-30, but there was no change in the knocking frequency or volume. I'm a decent mechanic, but I'm not sure how to diagnose a random noise I can't pinpoint. Any help you guys have would be appreciated.
