I have a 2005 Buick Century that is used for short trips to school , work , errands , etc. with average length of trip 6 to 10 miles , 90% suburban driving and approx. 12K miles a year usage (rarely gets out on the highway ). I am looking to only change the oil on this car once every six months / 7,500 miles . Will Mobil 1 EP 5W 30 buy me any added protection over Mobil 1 5W 30 for the above car & driving conditions ?
 
I prefer the EP it's only $2-3 more for 5 quarts and an M1 filter at Autozone when it's on sale.
 
I'd say just the standard. I run Mobil 1 5w30 in my wife's Jag and I'm planning on 1 yr OCIs backed up by UOAs to be safe. Not really a short tripper, but the majority of trips that aren't family outings are around 10 miles and it sees around 7k miles a year
 
Tbn retention should be better with the new API SN formulation which starts out with a 8-9 tbn.

How many miles are on it?
 
Got 96K miles on the Buick Century. Other key points : Two sons that drive it are not much for a proper warm up - they tend to just get in and go (much to my preaching otherwise) . Lastly, I hate to change the oil on this Buick : Even on ramps there is not much space underneith and GM could not have put the filter in a worse place - rear of the engine , way up high where you have to replace / install the filter by feel alone (I use either M1 , Purolator 1 or Bosch Distance Plus filters) . So to conclude : Start up protection and longest OCI interval I can safely get away is the goal between either M1 or using M1 EP .
