Wont hurt as long as they are MC or Visa, but do you spend more on gas than anything else?
Amex gives you 6% on groceries.
Ducks gives you 5% on gas and sporting goods.
Savor gives you 4% on dining and entertainments.
Uber gives you 3% on travel and cell phone protection.
etc etc etc

I think it depends on a few variables. I have multiple cards on the same categories for utilization control. Sample:
I won't let any individual card I have get to 9% utilization when the statement cuts so when I get to 9%, I start using the other card I have for that category and alternate between the two. Now if your limit is high enough overall you may not have a need to flip flop, but if you do, it makes sure you don't get dinged for hitting 10% or more utilization on a card.
It's a bit OCD but it works well for me. I dont participate in the AZEO method and not doing that hasn't hurt me any bit. That just may be a reason why having a couple cards in the same category can help, but it does muddy up the pot (two due dates, two payments, breaks rewards across two cards taking longer to redeem, but if you can manage it and you're not trying to cash out rewards every month then it works). I cash out rewards once a year in NOV and use it as the xmas stash.
I agree with the above though - you might find a better return with a general bank card than specific gas card. I use my USAA Amex (5% Gas Stations) and flip to my PNC Cash Rewards VS (4% Gas Stations) when I hit the 9% mark.
Food for thought - are gas cards really getting the most bang for your buck from a rewards standpoint? A regular card, earning 3, 4, or 5% cash back on gas purchases might be a better route. Maybe even a 2% CB card might beat our a gas card rewards structure.
Maybe look into a regular card offering a decent CB instead?
Or just go for something like Savor with a simple $500 cash bonus, then downgrade or close it when the grass is greener elsewhere.
I Think One major brand gas card where you get gas from is fine but anymore than that not so much their are so many bank cards that offer better perks for that categorie
