Hi all,
I received 6l of Ford fully synth "formula f" oil today - the formula e type (which i used in the last oil fill up) is now obsolete and formula f is used by ford in mostly all cars, including mine (as verified by ford service dept.)
My question is do I need to drain the old oil as it's a different type (semi vs fully)
or can I just add to it with the new type of oil I have?
