Hi all,
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 Tom
