What gas do you suggest for a C5?

I hear that there are some premiums that should not be used. Any favorites out there and why?

Thanks,

Lynn

I tend to go to the big name dealers. Shell, Amoco(BP), Sunoco (when I can find it). I've heard that the no-name bargain brand stations buy whatever they can at the best price they can, so quality could be "iffy". And I always use the 93 octane stuff.

Yep, me too. I use 93 octane as I think the absolute best performance can be obtained from premium. I also try and use "Top Tier" fuels. Gas is purchased by the oil companies on an open market. Refining and the additives are what make gasoline "better". I am also a big believer in adding "Techron", a fuel additive, about every six months, whether I need it or not. Good stuff. It can be purchased at Chevron stations, automotive supply store like "Advance Auto", or Walmart.

I try to get to a Chevron station, but will use Mobil or BP(Amoco). The Z seems to perform very nicely on Amoco.

Welcome to the forum, BTW!!

I prefer Chevron when it's available. With their Techron additive I don't have the fuel quantity gage issues I do with other brands. Also, at least around here, Shell is always higher priced than everyone else. I won't forget that they took advantage after the last hurricane to come through here, selling reg. for almost $4 a gal.

Was it a company policy (Shell) or was it something the local dealers took upon themselves?

Excellent advice from exile.
Replacing the 2 fuel senders in the 2 gas tanks on a C5 (without a warranty)
can be very expensive. !

I can't answer that. If it was local, I hope those folks realize that it reflects badly on them and Shell in general. I do know that the Shell stations around here are always about .10/gal more than everyone else. Anyone else find that to be true of the Shell stations in their area?
