My car has 5,250 miles. Should I get the oil changed now or wait until 10,000k, what the oil countdown recommends. The car says I have about 49 percent oil life left.
Go by the OLM and you'll be fine.
I found it hard to wait past 5k miles to change the oil. I just can't bring myself to do it. I changed the oil at 5k on my 12 GT and now on my 15 GT I do the same. I can't imagine that it isn't better for the motor even though the recommendation is 10k.
It's not going to hurt anything waiting to 10,000 miles if that's when it needs to be done. Ford isn't going to recommend something that would be detrimental.
