I guess I should say that the car has been gone through by a previous owner/mechanic and had most things it could or would need after all these years replaced. Shocks, brake shoes, wheel cylinders, brake hoses and lines, springs, fuel pump, water pump, plugs, wires, cap/rotor, points, etc. Lots of little things that have added up to make it a very nice driving car that doesn't need much work. That being said, I would assume the timing chain has been done already at this point based on how thoroughly and carefully it has been cared for, but haven't checked it yet (and definitely will).
I did find that I am able to get Valvoline VR1 10w30 in 5qt jugs at Walmart here, single quarts are 20w50 so doing a 5qt jug and a single 20w50 would get an oil change a little thicker than all 10w30 if it is needing that (haven't seen it with 10w30 in it yet to see if it will turn the low oil pressure light on at a hot idle). I am also able to get Rotella T4-T6 at Walmart for $16-$24 a gallon so that is definitely an option, too. Walmart used to have the Castrol Classic as I've looked at it there before but they must've dropped it as I'm not seeing it or an empty space for it anymore.
