Default What oil for oil change

I have read lots of info on oil here but I am looking for a little more info.
I have a 1973 xlh that has 500 miles on rebuild and would like to change it.

#1 can i use synthetic oil now or not?

#2 my local stores have no 40,50,60 wt oils just 20-50 car oils
and 20-50 synthetic could I use these or order oil someplace.
thanks for any help.

You will no doubt get many different answers to this question.

I will start it off by saying you need to use Harley 60wt oil in both the engine, primary and transmission.

I would never use multi-viscosity oil in my Sportster.
If I were you and had no local Harley dealer, I would contact the closest dealer in your state and request the price to ship you some oil. I would be tempted to simply buy a case at a time.
That is my opinion on which oil a 1973 Sportster needs to be using.
And you are smart to change the oil after 500 miles since the rebuild. Don't ride it much more without changing the oil first.

Default I had a recent epiphany about oil...

...but first, please allow me to vent about reading YET another "What oil should I use?" question.
AAAAAAAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRRR GGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!! !!!!!!!!!!!!!

Okay now, let's move along.
After using NOTHING but H-D oil (60 weight) since '92, I've recently switched over to Valvoline VR1 Racing Oil.
I was clued in to this by friends who ride IHs & shovels --- they explained about how it's got the zinc additives that pushrod engines require.
The only place I can find it locally & on a steady basis is Autozone, but JEGS sells it if that's the way you've got to go.
At Autozone, the counter guy told me that the only people buying it are Harley riders, so they know their customers.
The stuff is GREAT.

What part of the country do you live in?
You could use 50wt in the cooler months and 70wt in the summer in Arizona or Texas, but 60wt is still the best choice.

I also forgot to note in my last post that I would not pour in Synthetic oil over the engine oil now in the bike.
I am uncertain how these oils would react to each other.
May or may not be OK, I just don't know myself.

Years ago in Southern Cal when my '77 XLCH was new, I ran HD 60wt in engine and trans. Never had a bit of trouble in the 2 years I owned that bike.

Here in the PNW where it's much cooler (Goddamn freezing most of the time!!!) I run HD 50wt in the summer and 20-50 in the winter. I don't ride much in the winter but like the lighter oil for better startup and oiling when it's in the 40's.

My HD manual suggests 70 for my locale. What I do know is that oil has a SAE rating. So, I am goimg to check the rating on HD or other "motorcycle" oils and compare them with the ratings on other oils. Reason being, is that if you by a case, it is generally less expensive. And if Pennzoil or whatever has the same rating as HD, Drag Spec, or whatever, why pay the difference? However, I do believe in putting non-ethanol gas in my machine.

I am from Michigan.
I looked at auto zone but must have missed it,the web site shows they stock
Valvoline VR1 50wt
I will have to check with them if they can get the 60wt
also I take it the 60wt would work for the primary also?
