I bought gasoline Sunday. Afterwards I passed a Maverik that sold ‘eco 88 unleaded’ for 10¢ less than regular unleaded. I think this is a little too much ethanol for my '87 Toyota pickup. Anyone know anything about it? I didn’t see it at any other station.

Sweet corn is still $1 per pound at Costco, has there been a great increase in price for cattle corn?

[image] TheWonderful90s: Technically E-15 is 88 octane so it is a form of premium. But I assume you need 89 octane or better. I doubt there’s an official definition of premium, but I’d say most people consider premium to be 91 and mid-grade to be 89. In any event, my car uses 91, as does my w…

The power of Marketing. The word Premium is applied to a gas that’s higher octane. Premium implies BETTER or IMPROVED. It’s NOT. It’s just higher octane. It’s no wonder that a large percentage of people who drive vehicles which only require 87 octane are suckered into buying a higher octane because …

[image] MikeInNH: Premium implies BETTER or IMPROVED. It’s NOT. I’ve heard that premium had better additives in the old days, although I don’t know how true that was. Today, that’s not the case, as you say.

You can call a grade of gasoline Alfred if you wish but the only thing that matters is the octane rating. All manufacturers tell you the minimum octane rating to use and many recommend higher. 88 Eco is nothing more than marketing.

Yeah, nothing “Eco” about it. Biofuels range from breakeven maybe (corn ethanol) to environmental disasters (diesel from palm oil).

[image] TheWonderful90s: Technically E-15 is 88 octane so it is a form of premium 88 octane isn’t premium, it’s not even mid-grade. 91 octane is the bare minimum for “premium”, with most areas of the country having 92-93 octane for premium. If your car requires premium then 88 or 89 octane …

I’m old enough to remember we always called it ethel (don’t know to spell it). Maybe that was just shell.

E85 was $4.40 and regular E10 was $4.85 at a local gas station. If ethanol contains .7 times as much energy then E85 should contain 0.745 times the energy as regular gas. E10 is .97 times the energy. The difference is 0.775 compared to E10. 4.40 / .775 = $5.677. E85 users are paying the equivalent of $5.677 for gasoline
