Here is some basic information on the oil consumption lawsuit; your buddy may be interested:

Ironically, I think my Forester was traded in for a RAV4 for the same reason!

I have had the oil consumption test done, and have qualified for the 8 year/100k warranty on oil consumption. However, after discussing it with several mechanic friends, I have chosen not to have some dealership monkey tear my flat-4 apart to replace half the motor. Nooooo thank you. There are plenty of horror stories out there about this whole event turning into a shitshow. Subaru has ended up replacing several engines because the dealers cannot do the job right. I will just keep adding oil at a rate that I consider to be reasonable. Like I said, I really do not care, but I know I am in the minority.
His Outback had the 3.6L H-6 engine, which wasn't listed in that bulletin. He still had a ridiculous level of oil consumption. You'd think the issue might exist in other engines if they were designed by the same engineers.

Interestingly, this circles back to the ZDDP issue. The concern was that in older engines with higher oil consumption, more of the phosphorus in ZDDP would make its way into the exhaust and poison the catalyst prematurely. With such high oil consumption on low mileage engines, I'd think Subaru would be concerned about this issue since they have to warranty the cats through 100,000 miles.
