Yes, do whatever the warranty says! After that...
My last 3 vehicles have easily gone past 250 K miles (no known signs of engine wear, using Mobil 1 0W20 and 20K OCI's.
One is a severe service tow vehicle, oil changes are still on the same schedule, this is about once a year. Anyway, I suspect your 7500 mile OCI's will be a piece of cake for that oil.
The oldest of the three would have used mostly Mobil 1 5W30 for the first 125 K miles - 0W20 was not yet unavailable.
I replaced the valve cover gasket on the commuter Escort at about 210 K miles - the valve area seemed very clean and no sludge or debris was visible anywhere.
Ironically the failed valve cover gasket never did leak until it just jumped out in one corner, like squirting out a watermelon seed - and left a sudden stain on the garage floor each night for a week, until I could change it.
Perhaps that was caused by Mobil 1 being TOO slippery!! LOL
