66GMC Thanks for verifying that.
I run premium in virtually everything I own. As you've said, it runs better.

I believe that the better running = better fuel mileage which seems to offset the additional cost somewhat. On my fuel-injected 3.8's, I honesly believe that the ethanol-free fuel is easier on those expensive fuel injectors, too, AND the additives help to keep the nozzles clean.

Perhaps its a case of "Pay now (at the pump) or pay later?"

My old 1993 GMC "ta-da-dump" truck gets the regular fuel.

77pontolds Yes, that was for premium unleaded.

Was that also Premium Unleaded?
We pay about $0.10 per litre more for Premium, which would be roughly $0.40 tp $0.45 per US Gal. (1 US Gal = 3.78 Litres)

66GMC I just found a source that confirms that ALL premium fuel sold in Alberta is ethanol-free ... as long as the data is still current.

Pure-gas.org
(This site lists locations by US state as well.)

Further reading (elsewhere) says that ethanol is a big "no-no" in a marine environment as well as in 2-cycle engines in general.

Also worthy of mention is that NGK says premium fuel might be hard on sparkplugs. I wonder if that statement was made prior to ethanol blending?

High Octane > Problem Solver or Problem Creator?
If OEM vehicle/engine specifications state the use of high octane, or specify an octane level rating to use, this must be complied with to prevent engine component damage. The use of lower octane than recommended can cause detonation and engine damage. The use of higher than recommended can cause fouling problems, even more so in the cooler climates.

The reason for this is the higher the octane the slower the burn rate which either cools or heats the combustion chamber outside of OEM specifications. This can be especially prevalent in cold climates or 2 stroke applications where the use of the incorrect fuel leads to a high failure rate on spark plugs! Always comply with the specified fuel rating for your vehicle.

Note: Premium fuel is considered 91 or 92 by OEM

Ethanol Free Premium Coalition New York Is Not A Mandatory E10 State

--------------------------------------------------------------------------------

Prohibit Ethanol Blending In All Premium Unleaded Gasoline

Every mandatory E10 state has exemptions to their blending law, because there are a number of piston engine applications that should not, and some that cannot, use ethanol blended gasoline. Unfortunately the exemptions are not uniform. They vary from only one exemption in Washington, aircraft, to a universal exemption of premium unleaded in Missouri. All states exempt aircraft usage, but most states like Oregon and Washington make it almost impossible to get unblended gasoline. Oregon is the only state that allows for unblended regular and premium gasoline for the exemptions, and then makes it almost impossible to get any unblended gasoline. All other mandatory ethanol states just allow clear premium unleaded gasoline for the exempted classes.

The following piston engine applications should not use ethanol blended gasoline:
■ Any 2 cycle engine used in tools, watercraft, snowmobiles, etc., or small 4 cycle engines.
■ Any engines used in an emergency stationary engine application like a generator or a pump, especially in a humid climate.
■ All watercraft. Ethanol blended gasoline should never be used in a marine environment.
■ Antique and classic cars and classic motorcycles.
■ All aircraft.
All of these users must be able to get ethanol free (E0) gasoline. If you live in a state without a mandatory ethanol blending law, you have no exemptions, ethanol will eventually be blended into all of your unleaded gasoline and there is no requirement in EISA 2007 to label gas pumps with ethanol content.
All of this mumbo-jumbo comes to one thing.
I can see the day coming where the only place we can buy ethanol-free gasoline will be your local airport (or an av-gas distributor)

I buy my gasoline locally at a Federated Co-op filling station, and was told that their premium grade did not contain ethanol.

IIRC, the percentages were:
Regular 10%
Mid-Grade 5%
Premium 0%

I have googled this, and it sounds like there is a push for this in the US, but it appears that you are likely correct in what you say.

All I can say to that is to make your voices heard ... hopefully get some legislation?

cobalt327 There used to be a forum to let people know about good or bad experiences- Hotrodders Company Reviews. Link is broken now, though.

BUT!! I see the Crankshaft Coalition wiki update is no longer stuck, so I'd like to say thank you for that.

66GMC "Nothing beats Reliability - In products or in people."

Bravo Holley!!!

slownugly x2 compton!! A companys customer service sells me eveytime. Dont get me wrong, I like a good product, but when youre not buying a stock replacement and trying to match something up to your custom project its nice to have good, knowledgable techs to talk to and insure you get what you need.
