For me it was Pennzoil SAE 30 for I believe dads old lawnmower. Lately, it was some Super Tech HD 30
What was the first straight weight oil you bought?

Back in the 60's and early 70's, there was a ton of 30w used.

Valvoline conventional was always on sale at Bomgaars, Pennzoil conventional sometimes until one of my friends brother told me not to use it because it had wax in it 
Probably 30 of some sort . That would be close to 50 years ago . No way I remember any of the details .
Pennzoil SAE30 then 40.

LOL that was the old 30/40's, I recall my dad leaving some QS 40 outside during the winter, you could literally see the frozen wax clumps in the oil when he tried to pour it out.

The new SN approved straight weights would probably pass a 20W or 25W test easily, the oil I am using has a pour point of -30C

It was in the 60's but I don't remember the brand. Sorry...
I'm only in my 20s, so I think when I was like 16 I bought some Accel brand straight 30 Non-detergent oil and mixed it with some paint thinner to apply it to bike chains. then maybe a few years later I bought a quart of supertech straight 30 to put in my mom's lawn mower in 2014, I think those were the only two times I bought straight 30.
Probably supertech HD 30 for a lawnmower. As for sae 30 in a car, I believe it was delo 400.
I worked for a company for 17 years that used Delo 400 straight 30 in their fleet of forklifts, class 8 trucks their fleet cars and service vans. Those engines lasted and lasted.
A bunch of Pennzoil SAE30 on clearance from somewhere. I still have some of it.
Valvoline.
