What is

RE: What is
Everybody has their one oil they swear by, but they are all pretty close to the same as long as it is a synthetic. The receipts for my car say that it had castrol 5W-30 for the first 20,000 then mobil 1 5W-30 for the next 75,000. I have had it for 6,000 miles and run Mobil 1 Extended Performance 5W-30. There has never been any repairs to the engine or turbos of my car so I am very confident in this oil.
