According to 'Lester', Conoco Phillips is the oil company from which Motorcraft sources their oils. So, I get my semi synthetic 5w20 TropArtic Conoco Phillips from Sams Club much cheaper than the Motorcraft from Walmart...
I'm at 93k on my '05. The only failure with mine was the FICM and that was under warranty. It's never had as much as the EGR valve serviced and runs great.
Thanks guys, and you too, Carl.... So far we're really liking it. I took it today to get it's MO. safety and emissions inspection. The inspector commented that the brakes looked like new..... :)
It was a pleasant surprise, Frank. I wasn't peddling the thing either. I was contantly trying to be the 'allowable' 5mph over the speedlimit and found myself many times 10 or a bit more over.
