7500 miles may
be perfectly fine depending upon usage patterns and engine condition. Don't ever go that far without verifying with UOAs along the way. If the engine is healthy, 7500 miles is a cake-walk for the Amsoil EaO filter. 15,000 miles on one EaO is doable if the engine is healthy and clean (inside). Again, don't try this without verifying.
