For the A, I simply go to Walmart and grab whatever is cheapest. I save the good stuff $$ for my newer higher performance vehicles. I change it once a year, since I only drive her about 1k miles a year, and the change occurs right before putting Elvira away for her winter's sleep. That way, no acids in the oil eating her guts while she sleeps. A new filter always goes along with an oil change.

But, you do whatever you want, I'm not saying you are wrong...

When I have her on the lift changing oil, I grease/oil the snot out of everything I can find, and check for stuff falling off. Then I drop her down and check the battery acid level, and put her to bed. (Then, someone decides we need one more tour, and spoils the whole deal.)

NOTE:
It's also a good idea to look her ( the A) over real good and make a list of anything she needs and give it to my boss, er, eh, wife. She will drag that list out now and then and nag me until I perform the tasks. Hopefully she succeeds before a total failure of something on the list, but then I'm pretty lazy...
