Last Sunday, we went for a driving lesson for my wife (her drive test is coming up shortly) and on the way we visited Costco to fill up the fuel tank and have pizza for lunch. The petrol (ULP 91) prices have hit 140c per litre everywhere, because of the high demand in the summer, yet as a Costco member, I could buy them at 118c, which was about 15% cheaper. We filled up the tank and came home.
After I reversed the car in the car port at my apartment, I noticed a trail of liquid on the driveway leading to the carport. After a while, I noticed there was a bit of an oil spill under the car. It was a little spill, and I had to rush to a birthday party in the evening, so I went there and came back. I could notice more oil where I parked the car as well. Worried, I smoothly drove home (I drive smoothly anyways) which was only a 5 minutes away. I was watching for the low oil pressure warning whole through the trip back home, but it never came on. I never could feel or heard anything out of the ordinary from the engine either.
Once I parked the car, there was a new oil trail close (parallel) to the old one. So it was still leaking. I called my father and asked what I can do and he told me to check the oil level immediately even though I had driven the car few minutes earlier and even though it was not a perfectly flat surface. The carport floor ramps slightly forward. I saw NOTHING on the dipstick. NOTHING! I initially thought all of the engine oil had leaked out. The oil spill under the engine was much bigger now as well.

So, I couldn't move the car. I talked to a mobile mechanic and he told me that there is a known issue with the Toyota Aurions prior to 2008 where the oil cooling hose which has a rubber midsection can get damaged over time and leak oil, and Toyota should replace it free of charge.
