I would agree with the Quoted Statement
Not sure if it is still Relevant, i hear at least 4000 miles is ok almost always
maybe longer
Looking in Owners Manual, it has List of "Extreme Circumstances," one of which lists "Stop-and-Go Driving."
Rule of thumb, going by Old Oil Change Bible:
a. If you Stop at a Light, it is "Extreme Driving" - Normal conditions would be you cruise on highway, no application of Brakes with which to cause Wear
b. If you do drive in Extreme Circumstances, including but not limited to coming to a full stop and then taking off at a ligt, then a 3000 Mile Oil Change is recommended. As per Manufacturer of most cars, incl. Ford (And Chevy... who -didnt- recommend a 3000 mile OCI before Synthetics came about mainstream in more than a Corvette)
But why should we trust those that made our cars. We know better
