I used to think the same thing about Fram, I was very anti-Fram for many years but I learned better.
Here's what changed my mind...

No need to change at 3500 mile intervals, that's just something dreamed up by the quick-change joints like Jiffylube.

So, so true. Growing up everyone used to drill it into me that you needed to change your oil at 3k miles.
The more I read and more educated I became, the more I realized that was nothing more than a scam. I change my oil usually around 5k, but I've gone until 7k and it was just fine as well.
Of course, consider how you drive. If your vehicle is a track only vehicle (like my race only motorcycle), then yeah, you want to change the oil much, much sooner. But for a low revving TJ engine... You'll be fine going to 5k.
Nothing lasted long when you & I were kids Stinger. I remember tires wearing out at 10k miles and we were lucky to go 10k miles between needing to install new plugs, points, condenser, etc. Oils weren't nearly as good and a lot of them caused problems like sludge. Carburetors were a PITA, I don't remember much longevity or reliability to anything back then. The problems we have with modern engines are harder to diagnose but overall, I'd rather have a modern fuel injected engine than one of those PITA carb'd engines I grew up with.
I had a 62 Chevy pickup with a 283 that burned a quart of oil every 100 miles. I never bothered to change oil. I just added oil and would change the canister oil filter once in a while.
Well now there was no reason for that 'cause for less than $150 I could have replaced the rings and all bearings.
I was about 10 years before you. We only made .85 washing dishes in a night club. Car payment on my 56 Chevy wagon was 16.00. And to the OPs point I used Fram---canistersBack then, 1978, I was working for $2.00 an hour and I was able to get all the used oil I drained from log trucks. 150 bucks was like $1500.00 today.
I did get an almost new 283 from a guy that just put it in a 65 impala and the frame rotted. He gave me the Impala and I put an engine in a Ford pickup for him. The good old days.
