2006 expedition 5.4 with 130k miles.
The plan was to use a quality Synthetic to get through the winter months, run it 7500 miles and change it when the weather is warmer.
I'm currently at 5k and the motor just sounds noisy.
If it were summer, I don't think I'd get this feeling like it needs to be changed, but since I last changed the oil, the average low has been 0°F or lower (nov, dec, & jan). So I've had lots of cold morning starts, some of which were -15°F or lower. I went back through the weather log and there were about 28 days that were below zero for the morning low.
I'm just questioning my plan to extend OCI's over the winter months. With the cold mornings and copious warm up times ..... I guess I'm getting cold feet.
the weather is supposed to be almost 30°F tomorrow, so it wouldn't be a bad day to do an oil change.
the last time I tried to do an extended OCI with synthetic over the winter the numbers did not come back so good. (NAPA 5w20):

what says the group?
Currently filled with PP 5w30 and a Bosch D+ filter.
the motor just sounds noisy to me ... more so than normal.
if I change it now there won't be a UOA. if I change it in another month, i'll probably do a UOA.
seems like a waste to dump the PP, but oil is cheaper than an engine.
