I think if you do some research, you'll find Costco is considered a top tier fuel. I've been running 91 octane ever since I've owned the car (60,000 miles). Never had a problem.
I'd be more worried about the time wasted in the huge line up to save a few dollars.
I was thinking the same thing. Save 10 cents a gallon and wait in line for 45 minutes. **** that. The Costco we shop at I have never seen the line shorter than 10 deep at every pump.

You need to avoid it at the peak times then. I filled up at Costco at around 7:30 this evening and didn't have to wait for a pump at all.
Even when it's busy I've never waited 45 minutes, maybe 10. Even with a long wait it's worth it to save money though, for instance tonight the price of premium at Costco was $1.21 a liter. At most of the major stations around here including Shell, it was $1.47. With a 60L fillup that saves over $15! If you fill up 20 times a year that's a $300 savings.

That makes a lot of sense. Unfortunately the Costco's near me are busy all the time (apparently not in the morning on weekdays but I am at work). I am a baby and wont even wait for 5 minutes. (average wait here is 10-15min)

Have to hit them at 700 pm on Saturday night no one there! 92 octane here.
Were I a member of Costco, I'd check em out on price. I've got one 9 miles from my residence. Been using Walmart 93. Thanks to Foosh, who saved my engine from 87 with his advise.

Costco is "top-tier" gasoline in our market. Also, most premium gasoline is 93 octane here in Virginia. We're not Denver. LOL!
As for other brands that are considered top-tier fuels, they include Exxon/Mobil, BP/Amoco, Valero and Shell. This may vary in other markets, though, as they have brands of gasoline that are unheard of around here.
By the way, I never see Chevron or Texaco any more and have noticed a resurgence of Gulf stations. I have no idea if they are in the top-tier league, though. My Corvette gets nothing but premium from Costco, Shell, Valero or BP.
I use Costco 93 and luckily the Norfolk store usually has drive up and pump gas lines. While visiting friends near Baltimore I saw huge lines at Costco as the saving there were closer to 40 cents/gal. I paid th extra, hate lines. Costco is Top Tier.
I use Costco premium gas in my Corvette. It is a top-tier fuel. Just ask the attendant what time the line is shortest. I rarely have more than one or two cars in front of me when I go there.
