Hello folks inaugural post here, I have read this topic because I am curious about whether it would be advisable to run any different oil in an FB 20 engine to prevent the oil consumption issue. It seems as though from what Numbchux states early on in the thread, though that this is really more of a 'either you have it or you don't' deal. So far we've noticed little to no change in oil level during its first 5000 mile interval.
See my trouble that my wife bought this 2013 Impreza with 18K on it to replace her '06 Prius which melted down its crankshaft at 120K when it ran out of oil. The car had never leaked a drop and was well maintained up to that point. The mechanic that disassembled the dead Prius motor said it all looked great inside and found no reason for the excessive oil consumption issue. He said that several different manufacturers are having this oil consumption issue and he felt it was associated with the higher viscosity oils newer engines are using to improve efficiency. Now i am dismayed to learn that our 2013 happens to be one of the years listed this new law suit for the same
problem. Any thoughts would be appreciated. And yes my wife is learning about dipstick use at fill ups!
