Re: Alcohol in gasoline (spin-off from pulsing engine)

I just had what I think is my first bad experience with Ethanol blended fuels this weekend.

I have a 1983 Jeep J20 3/4 ton pickup  that I only use when I need a real heavy duty 4 wheel drive job done. I'd been having trouble starting it lately and a couple months ago it just would not start, so I just chalked it up to being lazy and not gettin around to rebuilding the carb. 

I just used the V10 Ram.

Well I kept watchin the grass grow up around it when I was mowing and it started to bug me......to make a long story short I ended up replacing all the assembly line fuel hose....I know it was factory because it still had those crimp clamps that look like little CV boot clamps.

The hose had the feel of silly putty and would stay flat if you squeezed it and it was all swelled up on the inside.

Here are a few pics.

...So E15 probably will not dissolve the fuel systems in late model
cars and maybe their engine computers, knock sensors and other parts
can recognize and correctly respond to higher octane E15, but what
about my 1979 Chrysler? There the news is not good because there
really is no clear news. I was excited when I saw a US government
sponsored report on the impact of E15 on “legacy” vehicles. That is
until I discovered that legacy only meant 10 years old! The study only
indicated they were reasonably confident that E15 would not have a
negative impact on 2001 and newer, legacy vehicles.

There have been studies of off road engines found in lawn mowers,
marine engines, snowmobiles, etc. that could relate to old cars. Air-
cooled weed whackers and old cars with carburetors do not have oxygen
sensors that provide the engine with feedback on the correctness of
the fuel mixture. There are concerns that ethanol could create too
lean a mixture and too much heat. Ethanol might dissolve rubber
components or the composite body of my Chrysler’s Carter four-barrel
carburetor. There are just too many different old engines and engines
not designed for ethanol for anyone to make any 100% guarantees about
the impact of E15, E20 or higher ethanol concentrations.

Increasing ethanol concentrations in five percent increments appears
to be nothing but a “let’s see what happens” gamble for truly old
cars. With all the old cars and other engines not designed for ethanol
out there, hopefully 100% gasoline or at least E10 will remain
available. Now I better understand why E15 is such a political,
environmental, technical and legal hot potato. -- Tom Taylor
