(ATTN: this is a subject I am fanatical about and have researched A LOT because of my affinity for combustion gas engined motor equipped vehicles since I was 3 yrs old
cabon-based petroleum .. Teter`s Store/marina in Cheatham County ,TN(or any of the stores that I frequent along I-75 listed on Pure-Gas.org that I map on treks to go wheeling or visit my folks in Blue Ridge,Ga, or in-laws in Marietta,Ga.) . Non-ethanol 89 Oct
has been used for 75k* of 80 total thousand miles on my 3.8l 2011 with a Flashpaq and comp Dynomax pre-ax dump.
I serviced fuel lines , filter and injectors at 64k and they did not need replacing ( tho i did anyway) & I have never even had so-much as a stutter or backfire. Hoses are all
Ethanol jellifies hoses and other fuel system vitals and leaves deposits on rings and also crud built-up from it`s water retention. The government did this back during fuel crisis as it also helped farmer`s who were losing money with all the corn being grown. If it were so great, why didn't they run it in gas 50 years ago? I do not have much motor in my rig but until I do, I gave it some love the entire time at least confident in not having corn alcohol added into my gasoline. Once you are familiar with the non-ethanol stations from the great Pure-Gas app for mobile-phone in your area, no reason but cost ( about 10 cents more per gallon) to object. Fuck Ethanol ; it is where most failures result from , IMHO, in older autos from last 25 years. Look it up. My 3.8 purrslike a kitten ( I also have only run Amsoil 5w-30 in it for the total 80k & it`s valves and innards look new. )
The second President Bush made a decision to offset some of our dependence on foreign oil with domestically produced alcohol, and the Corn Belt senators agreed. Ethanol plants have mushroomed, ramping up U.S. production from 1.77 billion gallons in 2001 to 10.75 billion gallons in 2009. Politics aside, odds are near 100 percent that there's as much as 10 percent alcohol in the gasoline you're pumping into your Jeep and that 5-gallon can you use to fuel all your other gas engines up ...or strapped to back of your rig in your spare gas. Additives to remove the phase separated H2O from the tank don`t work .The temperature of the fuel is a factor as well. Here's the scenario: You fill up the Jeep or gas can with fuel that, for a variety of reasons, is near its water-saturation point and at 60 degrees. Overnight, the temperature drops 20 degrees, and all the water and alcohol settle out even though no extra water has crept in. Guess what? The engine won't run when the fuel pickup is sucking up the alcohol–water mix.
Worse yet, the gasoline remaining above the water has probably lost three octane points, because today's gasoline relies heavily on the high-octane equivalence (130) of alcohol to achieve its octane rating. It's also missing a bunch of additives that stayed in the alcohol—so the entire tankful should be drained and disposed of as hazardous waste.
And no, adding more alcohol, in the form of fuel-line de-icer( HEET or other additives) , lacquer thinner or cheap vodka will never restore that gasoline to usefulness. You don't want to add yet more alcohol, lest the increased concentration turns your *carburetor float or the fuel-rail to Jell-O. The only acceptable way to attempt to save the gas in the tank is to add a large amount of gasoline that's got a very low moisture content. Problem is, there's no good way to tell if pump gas has a little or a lot of water on board. You stand the chance of having twice as much phase-separated, unusable gasoline as before.
love you motors. Love non-ethanol.
(I have two other Jeeps + have owned 5 altogether; this is the first one ( the JKUr) that has not run Chevron ,Shell or ( god forbid) Mapco or QT fuels ( all of which come from the same terminal, yes) and of the current three ( `94 YJ Sahara, 182k |`95 UpCountry XJ which is about to hit 400,000 original wife miles! It is her daily driver and she LOVES it like one of our children ) | `11 JKUs that was converted to JKUr which just rolled over to 80k
) the first two were not ethanol free and have their fuel filters and systems cleaned of GUNK each two years. Of the choices, Chevron with Tecron is the best petroleum fuel . The older two occasionally -after they sit mor than three days- get stutters or rough idles at startup unless I shake up the tank by vigorously rocking the whole Jeep back and forth side to side before starting if they have set for a long time. The Inline 6 engine could likely run on PGA ,a can of beans or piss probably & if need be ( the things are BEASTS) , it is so rugged and tank-like. I run Shell Rotella for Diesel at 15w40 in those with ProLong oil additive So, it can take the abuse of ethanol enriched fuel better cuz it don`t give a damn .
The little Chrysler 3.3|3.6|3.8 V6 is altogether different & MUCH more sensitive than the venerable Inline6 4.0HO motor and thus why I chose the non-ethanol from day one*.
(* i bought mu `11 w/ 5k on it after some school aged girl`s father returned it after buying it for her & she hated it. Saved $8,500 over buying the same one with 0 miles so I didn`t fill it with whatever went in the first 5k miles
