| Re: Rising cost of food rant I'm back reading, and I see some bad info to the consumer. "Premium" is not premium, regardless of state, and has no indication of the amount of ethanol. It's a federal mandate on what Premium is. So if there's 15% in "low grade", there's 15% in Premium.
Premium fuel is the amount of octane, which IS the oxygenator. Lower octane fuel is better all around, and it's a bain that some engines actually HAVE to use it. 87 is recommended, but using more does nothing but rob power. I HAVE to use at least the 90 octane in a 12.7:1 compression engine. That's still about premium, but can get away with not. Ten years ago, it was 78 octane for best power and reliablity with 11.9:1/12.1:1 engines. The suggestion for a 10.1:1 3.7L V6 is 87 octane. I have no need for high 92 Octane fuel in the Jeeps. Do so and I get less power and pay more for it. So it's worth noting what octane need is there, and what premium actually means.
If common fuel is 15%, then unleaded premium with 0% Ethanol is purely un-oxygenated. It's freaking race gas, and worth every penny. Also not DOT legal and should never be bought or sold for highway use. We have a plant in SD, and it shows that 10% is indeed minimal in all gas. So what's probably happening here is what they have to report to the user. It's all E10 at best unless it's a flex vehicle, and thus labeled. Being that SD is one of the cow-toed states...no study from within is reliable.
The sticker is trusted more than the data.
