Coming up on my first oil change. What oil should I use. 07' 5.;L

I don't know off hand, but your oil cap should say what to use.

JoeLocal

The oil cap says what brand to use?

otto457

Motorcraft 5w20 syn blend
Motorcraft FL820S oil filter

JoeLocal

Is that still ok if the guy before me did not use a synth oil

ToughFX4

Yea, 5w20 820s motorcraft semi-synthetic.

JoeLocal

Just wondering but why not full synth.

Sorry for a probably stupid question

BkoJoe

because its recommended.. there are way to many oil related issues with these motors to play around with simple things like oil... stick with stock and you cant go wrong... that's assuming you meant 5.4L

otto457

A semi syn blend can accel in many different situations, where a regular dino oil or full synthetic would lack. Yes there are situations that a full synthetic is not best, contrary to what every synthetic marketer gets you to believe. It's the best oil for all the different situations a Ford motor might see.
