Now, there are plans to increase alcohol content from ten percent to fifteen. Those of us with old cars are being forced to pay a premium for non alcohol fuel. Here, in Iowa, the cost is fifty cents per gallon. Soon, even that with disappear, according to the marketers.. If that is true, kiss our hobby goodbye! lazy69ranch 09-30-2014 @ 8:44 PM reply profile send p.m. Member Posts: 50 Joined: May 2012 The additional 50 cents sounds pretty good from CA...I'm already paying $6.83/gal here in N. California for ethanol free 93. It's not readily available at just any fueling station. len47merc 10-01-2014 @ 6:46 AM reply profile send p.m. Senior Posts: 1165 Joined: Oct 2013 Here in central NC 89 octane with 10% ethanol is currently $3.19-$3.29/gal. Ethanol FREE 89 octane is $4.11, while 93 octane is running in the high $4 range (therefore $0.90-$1.00 premium here for ethanol free). Not sure if any value/benefit exists in investing in and running the 93 - have always been advised to run 89 to most closely replicate the octane levels in the late '40s. Perhaps this is incorrect - ? Giving full credit here to '40cpe' who posted the following info in a reply to a similar discussion back in ~July, you all may find the following website useful in your pursuit of your local locations that carry ethanol-free fuel: http://pure-gas.org/ The octane ratings have been found to not be accurate (here anyway) in all cases - recommend calling in advance of investing in the drive. Steve supereal 10-01-2014 @ 11:06 AM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 Non alcohol here (Iowa City) is $3.63/gallon. The low grade gasohol is $3.13. The pumps here use a common hose, so whatever was left over in the hose after the last use is what you get when you fill up. As most use the lowest price gas with alcohol, we all get some even when we pay the higher price. Old cars may tolerate this, but it is damaging to small engines. There is a move to eliminate all non alcohol gas so a higher grade of gasohol can be sold. When asked how those who have to have non-alcohol, the replay is that "there is always aviation fuel". I'm sure the FBO's at the airports would love to have us all come out to the airports. 40fordor 10-01-2014 @ 2:57 PM reply profile send p.m. New Member Posts: 116 Joined: Oct 2009 Super, or anyone that has an answer, What changes are required to ethanol proof our old Fords. I know some of the areas but probably not all. Thanks.

Easy to find but always .40-.60 more than regular 87 octane gasaohol. Soon the touring season will be ending and I'll go to the non-ethenol with Marine Stabil in my flathead Fords for the winter when the cars may sit for extended periods. For my mowers, weed eaters, chain saws, etc, etc. I use the non-ethenol and Marine Stable all year long. My feeling is that the water that the ethenol attracts is the main problem when equipment sits. Same applies to my collector cars and motorcycles. I think the octane was around 65 in the 1930's and the 87 octane today is plenty. Had a mechanic tell me that the higher octane really only is necessay with high compression engines and then only under extreme loads. My 21 stud flathead Fords are hardly high performance. 1934 Ford's since 1972 Bertha 10-03-2014 @ 4:17 AM reply profile send p.m. New Member Posts: 129 Joined: Nov 2009 Gloom & Doom?....just my experience. Fuel system & tank completely cleaned in 1979 two years after inheriting our '53'. Dual vac fuel pump and ceramic filter replaced, MMO & fuel stabilizers used continually. 89 10% since it was forced on us, Marine Sta-Bil, MMO every tankful, along with Aces at Spring get ready. So.....what do I change?

Phase separation, is when the Ethanol and water separate from the gasoline. This happens mainly after long storage, 1 yr or more. Fuel stabilizers can extend this period. The other volatile compounds in the gasoline that are added for air quality issues, can deteriorate in 60-90 days without a stabilizer. Some brands of gasoline have detergent additives that last longer and others can foul the plugs in carbureted cars in short periods. One brand caused a miss after driving the car only 100 miles. Seafoam was added to a fresh tank of gasoline and the miss went away. Always buy your gas at the busiest station you can find, and don't fill up when the station's tanks are being filled. Tom
