I've previously owned 7 Fords in nearly 30 years and, with one
exception, have been very happy with them. I will shortly be taking
delivery of my 8th - a "nearly new" UK Focus (with 1.6 Zetec petrol
engine) and would be very grateful for some advice...
The car will have to be "dealer serviced" for the remainder of the
manufacturer's warranty (nearly 2 years), and the "recommended service
interval" is, I believe, 12,000 miles / 12 months. I prefer more
frequent oil changes (on the basis that oil is cheaper than a new
engine !) so would like to do my own "interim" oil change after 6,000
miles (Shell semi-synthetic plus, of course, a Motorcraft filter !)
... does anyone know if such a "home" oil change will do anything
nasty to the engine management system ? eg: will it detect a "non
standard" oil change and demand I take it back to a Ford dealer for a
diagnostic check aka "laptop therapy" ?
I hesitate to ask this question of my Ford dealer because I know they
will insist their service schedules are OK !
Thanks in advance
