I recently purchased a Jug of Mobil Super 1000 5W-30. I have never used Mobil 1 Motor Oil before. I have heard very good things though. What I am inquiring about is how I would know what the manufacturing date is on my jug? I purchased it on sale at my local Canadian Tire, but it wasn't actually on the shelf. I had to ask an employee to see if it was still in stock. They found me one in the back room. My printed code on the jug is OEV15G20A B.09:05 00581- #8309 5912 Does anyone know how to decode Mobil 1's code? I wouldn't want to risk using something that might be very old stock. Thank you very much. Usually you can find an actual date but not on this one...
