Reliable oil change places on the road

[Redland1]

I have always done oil changes myself except for a couple of times that I have been out for a while and didn’t make it home on time.I’m running local in Oklahoma which is not my home state for the time being so I’m wondering what oil change places have been reliable for you guys? Also the couple of times I have gone to Speedco they only filled my oil filter halfway and I always fill it completely. Does it affect anything and should I tell them to fill it completely?

My OCI’s are 10-12k with 6mpg and I have been changing the fuel filters every time I do the the oil change.Is that too soon?
