Any good 5W-30 dino
oil will work just fine. I happen to like Castrol GTX, but there are other good ones on the market. If you drive more than about 10K miles a year, a true
synthetic will allow you to change the oil less often.

Maybe. It depends on the condition of the engine. If the engine 45 years old, but not driven much and is well maintained, then - once again - a good 5W-30 will keep the engine running strong and efficiently.
You need enough viscosity to maintain oil pressure and no more

Sometime you just have to do whatever helps you sleep at night.
