Which top tier gas for older cars?

What's wrong with Shell 87?
Over time used them all. Couldn't tell any difference in performance, mileage, etc. I would go for highest volume, cleanest station.
I got one of those on last fillup and car felt heavy and gas mileage is worse than with Chevron or Petro Canada 87 gas.
Personally, I rate Chevron and Petro Canada gas about same and better ones around here locally.
Weirdly it seems inconsistent for me too in the company Transit, almost like I have throttle flat spots & a little bogging when I use it. Pretty much running all BP 87 lately-even though it’s not TT Fuel listed anymore, it runs better with BP than Shell. Not sure why?
My Maverick Hybrid gets it best mileage on BP or Phillips. Shell here is just a PITA to get in and out of. BP is not run well in thsi area. The motorcycle likes Hy-Vee 91 octane E0, and it smells good, like gasoline should.
I use BP owned by a family friend. Shell is out of my budget.

I'm running Sinclair 87 in everything I have. My lawn equipment gets Sinclair 91.

Out of those choices, Sunoco > *
Another top tier thread. 
The EPA controls gasoline very tightly in this country. There are only 128 operational refineries in this country. Your not getting bad gas from the refiner East of the Mississippi. West maybe as they do import refined product more commonly.
Getting bad gas due to leaky tanks at the station is definitely possible. If it looks like the third world I avoid, but you never really know. Your at there mercy.
Most all fuel in an area comes from the same depot, with a different add pack. As we have heard from an actual person who's company delivers fuel - the add pack at the station may or may not match as advertised, dependent on what is available.
If your deathly worried about using top tier but its way more expensive, just run some P.E.A the tank before your next oil change.
Given there is a new Sunoco nearest you, I would go there unless its significantly cheaper somewhere else. It is top tier. I gas up at Sunoco here often - it or BP is usually cheapest.

Any top tier fuel will be fine.
Exxon/Mobil, Shell, BP whichever has the best price by me. All the stations by are pretty high volume and clean so I'll follow the price, convenience.
I haven't noticed any performance differences between them in my cars in my use.

If you can live with the price, Chevron is good. Pre-dosed with Techron
Actually BP and Amoco are both now Top Tier + certified, so this is a good choice as well.

Nobody on here gives a #@&^ about us in Vancouver.
1) Chevron
2)Shell
3)Petro Canada
4)Esso
...then SuperSave at Grandview and Clark which is always the cheapest in the city.
Not true.
My 'favorite' gas stations are name brands, ostensibly Top Tier, which, due to location and traffic flow, have lower prices than usual.
Ex:
1- I was in Waterbury, CT a couple of years ago and saw the Shell station was the cheapest. THAT'S an anomaly.
2- A Sunoco station near us has prices just a tad over DELTA, a big, local chain.
It’s funny here in NC. Three different tank farm terminals that receive fuel from one pipeline from the Gulf. Then there’s a dozen or more different locations-names selling from one of three terminals. There’s just not that much difference in any of them. The terminals don’t “blend” different tanker loads. The differences are octane ratings (pulled from different storage tanks), the few additional additives from each of the three terminals, and-or non-ethanol loads. What I can buy from Harris Teeter comes from the same terminal as what’s sold at Exxon. Sheets, Loves, Bucky’s and the list goes on will spot buy the cheapest loads from one of three terminals based on the daily price per load.
