The brand of oil shouldnt make much of a difference and as long as its the right viscosity. Could be that your TPS(trottle position sensor) is marginal, or even your CTS(coolant temp sensor). I've even read that it could be your ECU code needs to be updated. Have you tried resetting the ECU? Disconnect your negative battery cable for a few minutes and reconnect it. Right down your radio stations if you care. There's a section in the owners manual that tells you how to properly do this so your ECU re-learns your driving style. Mayb not fixe it, but worth a try.
All you guys probably have 2001 civics. I heard that ECU unit is messed up on some of them. My advice, if the car does not shut down, keep on driving, if it does - take it to the dealer and the first words out of your mouth should be WTF!
Good luck
