Hello folks. How many of you that use Motorcraft synthetic blend oil use it beyond say 7,500 miles? I was wondering as i read that it is a good Conocco Phillips product made for Ford to their specs. Also read that some people seem to think its like a WPP oil, which is amazing, but oh well I digress. I have it in the 11' Focus at the present with a TG-3614 filter. Thanks in advance, and to me it seems like a waste to run this oil to 7,500 miles, thats just me
