SUNOCO missing from TOP TIER list ,

What an absurd claim. Lets see all the claims for clogged fuel systems caused by non "Top Tier" gasoline. A little extra detergent for some marketing babble to make the sheep think they're getting "better" gas. Nonsense.

There was no Top Tier gasoline back in 84 and that Pontiac would have run and would still run just fine on any gasoline no name or name brand without fuel system clogging. Stop being an hysteric.

In the 80s there was a ton of questionable quality gasoline. At least today there's an EPA minimum cleanliness standard.

I don't know - the issue is they may not change their additive levels today.
But a year from now, or 2 months from now the corporate penny pinchers might and there's no way to know unless they rejoin top tier.
So, Top Tier gets my business.

Also, there wasn't ethanol in gas back then dirtying engines, so moot point.
