Straight gasoline has a shelf life of years, but with the addition of ethanol it drops significantly (3 months) due to ethanol's tendency of absorbing water and subsequently separating which has huge effects on octane rating.

I always cringe when I see "my mechanic buddy said". Five &*%^%^ minutes of googling will result in better info. A lot of people don't take into account that things might not be the same now as they were 30 years ago.
