..if Ford has already written the spec of the oil
and charging us for that 'development' why then
doesn't another lube producer 'match' that spec, via
testing etc, which is part of the spec, and produce an
oil that is cheaper? This is not a Ford issue it's the
other lubes that won't take the time to read the
spec, formulate what oil they have, test it & match
'honey'....You could just roll the dice and ignore
Ford's specs, but then Ford have specs for ALL lubes
etc, as do all mfg's..
