sounds like short tripped to me, I would do MaxLife 5w30 for the factory recommended 7,500 OCI and Fram Ultra for 15,000 Two OCI.
If you see no oil burning during those two OCI, MaxLife will clean up the car good enough for cheap.
Only after doing that I will move to Mobil 1/PP & PU/Castrol Syntec/Valvoline SynPower or Honestly even SuperTech Full Synthetic.
Reason I recommend that is because MaxLife is cheaper, you don't wanna be burning and then topping off with the expensive Mobil 1. Plus I used MaxLife in my D16Y7 and it took away the oil burning completely which from my understanding was the seal swelling additives in MaxLife.
Plus an OCI later I rebuilt my D16Y7, and WOW it was clean inside and the oil return holes in the piston were loosened up/cleaner and the ring grove area was a joke to clean up. Where as the other rebuilds I have done it takes forever to clean up the buildup on the piston.
was it the MaxLife loosing up the gunk or the SuperTech Full Synthetic that I used earlier at 3k OCI for 2 OCI? I'm not sure but on the MaxLife the engine didn't burn any oil whereas on the SuperTech it would burn 1 quart every 500 miles...
Is there a danger of using the "high mileage" oils and then stopping due to the seal conditioners?
I don't see how, if it needs the seal swelling additives(great), if not then no harm done.
That's like the ole wife's tale "oh my god switching to synthetics from Dino in your old car will cause leak"
