Nowadays you can burn gasohol or gasoline in a GM pickup.

How does one buy a patent? :h It's public information. I can even look at any patent I want to and make it for my own personal use, I just can't sell it to the public.

BTW, patents only last 14 to 20 years in general. You know what that means don't you? You can look up that carburetor and make it yourself and even sell it to the public because the patent ran out many, many years ago.

Now go out and put Big Oil out of business!! :R

Ok.....then where are you gonna get your gas???

I hope not. Even my Prius is limited to 10% ethanol.

go to the EPA site and read. The new proposal is to increase to 15%. The 10% has been in effect for 5 years.

We have 85 octane gas here and i run it all the time in my small truck and generators. I have had to run it in my motorcycle before as that was all that was available and its supposed to have 91 minimum. Never had an issue because of octane. Also you cant totally rely on the Pure-Gas site as its only updated when someone such as myself lets them know when a station doesnt sell it anymore of which i have done.

Do a quick search...federal regulations require ALL gasoline have 10% ethanol. As for using high octane than statd...it actually d damage in the long run as the higher octane burns colder causing higher deposits. In todays world there is no reason o design using higher then 87 octane. Hyundai engines run 10:1 compression on 87 as do most new cars. You can even lower the octane level used by introducing it slowly....the computer will adjust. It will result in slightly lower HP but no ill effects.

What and what? Not all US production cars like 87 octane fuel. I own a 2014 model year Ford that recommends 93 octane, but will live with 91. I have never tried 87, but I would think the knock sensors would force the car to try and pull way too much timing.

The federal government does not mandate that all gasoline contain ethanol. That may be a local or state requirement.
To answer the OP, the premium fuel without ethanol will give better mileage. You must do the math to see the difference in operating cost.

Octane is resistance to ignition. There's no benefit to using it in an engine that doesn't need it for high compression combustion chambers. Since it's harder to ignite, it can quiet detonation (pre-ignition) in engines that are prone to detonation.

Excellent explanation of the reason for using higher octane. Most vehicles can run on 87 octane (regular) these days. Even newer high performance engines with high compression engines will run on regular in a pinch, as the on board computer compensates for the lower octane.
As for you guys who claim they buy ethanol free gas, just beware that it is not always a requirement to reveal a fuel contains ethanol if it is 10 percent or less. A lack of an E10 sticker on the pump doesn't always mean ethanol free.
If anyone truly believes there was ever a 200 mpg carburetor that the oil companies bought out, please contact me. I have a bridge in Brooklyn I'd like to sell!

That would have been great for OTR trucks!;)

I used to have a 95 Buick Roadmaster - I used it for work travel. The LT1 engine would return the same $ per mile economy or a bit better using premium gasoline vs 87 gasohol. 27 mpUSgallon at 70-75mph - I kinda miss the old tub.
