<<I have a new 2004 Ford Escape, with the Duratec V6 3.0L.>>
My wife bought the same car 8 months ago and I have a new Lincoln LS with the
V6 (same block).
<<Currently the vehicle has 1,000 miles on it, and I would like to change the
oil & filter.>>
I used to be a fanatic about changing oil early but from discussions with many
people I do not think it is needed any more. I waited until 3000 in the Escape
and will do it at 3000 in the Lincoln. I don't think any car company
recommends a change of oil before 5000 in a new car anymore.
<<According to the manual, Ford recommends to use 5W-20
(Motorcraft semi-synthetic for U.S. and Motorcraft regular for Canada). I have
no idea why the difference between U.S. and Canada.>>
My guess is that since they did the CAFE (Corporate Average Fuel Economy) fuel
economy tests in US with the synthetic oil, they are required to recommend it.
Hence the difference. One of the main reasons 5W-20 was specified for your
engine is to increase the CAFE. CAFE is the combined average fuel economy of
all of a vehicle manufacturers product line. Minimum CAFE levels are specified
by the Federal Government. The change to a 5W-20 oil will allow Ford's overall
CAFE to increase by a very small amount, typically in the tenths of a mile per
gallon range. 5W-20 oil is a lighter viscosity than a 5W-30 oil and therefore
has less internal engine frictional losses, or less drag on the crankshaft,
pistons and valvetrain, which in turn promotes increased fuel economy.
I am using Mobile1 5W20 in both cars.
