A brand New Kroger's opened up by me, with Gas Pumps selling 93 Octane.
Question: would you hesitate using it?

shakinrock

I would not use it because it is not a top tier gas. Unless the C7's have a more robust fuel sensor unit inside the passenger side gas tank it is subject to corrosion over the long haul. Top tier gas will slow the corrosion process.

Definitely would use it, 93 octane just what you need.

93 Octane and more than likely lower prices than your typical free standing gas station...........

Oddly enough I shop at a Kroger and get the ten cent a gallon discount however I only buy gas across the street at the Quik Trip aka QT as it is Top Tier gasoline.

I also add five ounces of Lucas Upper Cylinder Lube every other tank and carry a bottle of Techron with me for out of town trips.

I normally use Shell (which is a Top Tier listed retailer) but prior to putting my Z06 up for the winter I did several fills at Meijer because their 93 octane is ethanol free. Top Tier basically requires a specific level of detergent additives be used. You can still get problematic fuel from a company owned or franchised seller of Top Tier branded fuels if the individual station doesn't properly maintain their storage and delivery systems.

I've used Kroger 93 without any issues and am not afraid to use it.

I would only use Top Tier gas in a Corvette. BTW, the reasons for using top tier gasoline is to prevent gunk, aka, contaminants building up in the injectors and/or pistons. Also, some of the additives in lower grade gasoline can contaminate the catalytic convertor.
If I owned a beater, I might want to save $0.10 per gallon. On a C7, no way. I drive about 5 miles passed the local stations to the nearest Shell station for my C7.

I used kroger gas in my daily turbo car for a month straight and it was pulling timing enough that you could feel it pretty easy. I stopped going to Kroger to avoid the knock it was causing.

I dont believe its true 93 octane fuel as i was getting detonation with it. Stick to shell or something proven to work. For N/A applications, you probably can get away with it just fine, but pay attention to how the car reacts.

If the truth were known you would be surprised who gets what out of those tankers. I have seen top tier tankers at the same distribution points as well as Generic named tankers. If it says 93 I will use it, providing they sell enough gas so it won't get stale.

And more junk from people that don't know what they are talking about. (yes, I used to be the terminal facility manager for an oil company)

Gas is a fungible commodity. Almost all gas comes from the same places. The only difference between brands is the additive package injected into the gas tanker at the loading rack.

ALL additive packages meet minimum federal standards. There is NOTHING in an additive package that will hurt a Cat Con.

Yes, some additive packages are better than others. But, You can easily add a bottle of Chevron Techron every couple of tanks and call it good.

The only requirement I use on where to get gas, is how busy the station is. The more busy, the less the chance of bad gas. (that's my theory based on working for an oil company) The less busy, the better the chance that the gas is old or contaminated.

What causes the octane rating to go from 87 to 93, a certain additive?

rrsperry

Octane is a function of what they decided the distillate fractions should be. Sort of like a blended scotch.

(and of course Oxygenates, or other things they add.) The additive packages injected while the tankers are loading are detergents and other stuff. Not octane boosters.

Oh, and gas only comes in two flavors, (depending on geographic region), regular, and premium. Mid grade is a 65-35 blend of reg and premium, either by a blender pump at the station, or at the loading rack when the truck loads.

That's why I liked the Kroger Gas option, everything is New; Pumps, Tanks and the Gas!

What's a "Kroger"?

vbdenny

Costco. top Tier 93. $2.13. I only use Top Tier fuels. Non-top tier fuels won't cause any noticeable problems for awhile but eventually it will. Why put economy gasoline into a Premium car? If fuel costs concern you you probably shouldn't have bought a Corvette.

Its a supermarket chain. They are also part of the Ralph's in the West and Winn-Dixie in the Florida area.

Foosh

Kroger is a grocery store chain located primarily in the southeast US w/ some stores in the mid-Atlantic.

No such thing as top tier gas! That's nonsense!

I'm a bit of a skeptic by nature and always try to confirm statements with facts. If you are believer in Consumer Reports here is a link to an article about Top Tier fuels. While I try to use Shell, BP, EXXON and Mobil I usually try to buy from stations that sell a lot of fuel. Fresh and non-contaminated fuel is more important to me that being rated Top Tier.
