I would not categorize it as a short tripper really. Depending on how you go it is around 8 miles on a state route to get to town, a trip into Atlanta proper is ~100 miles round trip almost all interstate.
As much as the ICE starts and stops I'm not sure it makes much difference how it is used. They have a reputation for being easy on oil...
I usually buy EP when it is the same price as regular M1 at Walmart.
We know TBN isn't linear, but 4 seems low for a ~5500 mile run when the Civic usually turns in a 3 or so at nearly 10,000.
This car has dealer service records at very near specified intervals (5000mi) since day one before I got it and I've been thinking about selling it which is my main objection to running it 10,000. I'm already off track with the filter change interval and use of Synthetic oil though, so I may go for it at the 90,000 change.
