You have the Holy Grail of driving conditions!
5 to 7.5k miles should be no sweat.
I agree. I think his engine can handle 5,000 on conventional. Pennzoil conventional should have good TBN after that mileage in his engine(assuming the interior is clean with the information OP has given)...
I still would like to see one UOA from his app after 5,000(at least) on Pennzoil conventional w/ TBN.
