here are some links for those who still think they get more power and cleaner engines...

Are you tempted to buy a high octane gasoline for your car because you want to improve its performance? If so, take note: the recommended gasoline for most cars is regular octane. In fact, in most cases, using a higher octane gasoline than your owner's manual recommends offers absolutely no benefit. It won't make your car perform better, go faster, get better mileage or run cleaner.
Will higher octane gasoline clean your engine better?
As a rule, high octane gasoline does not outperform regular octane in preventing engine deposits from forming, in removing them, or in cleaning your car's engine. In fact, the U.S. Environmental Protection Agency requires that all octane grades of all brands of gasoline contain engine cleaning detergent additives to protect against the build-up of harmful levels of engine deposits during the expected life of your car.

However, if you drive a luxury or high-performance car, it may need premium to prevent engine pinging or knocking, something that could cause problems down the road.
So there :P

87 but i only get gas from a chevron or shell, because ive heard that lot of the small ma&pa stations tend to put water in it to make it last or just buy the dirty gas. thats just what ive heard. plus i can tell the difference between the chevron/shell gas and the ma&pa gas my girl runs different with the ma&pa gas

thanks for posting that
I hope that experiment is working ok
if possible, try to connect a OBD-II scanner to your truck
and see if the oxygen sensor(s) are still
'flipping'
back and forth
around a 0.50 volt average
there is little question that the Ram PCM computer can adjust
the long and short term fuel trims
to compensate for how much
BTU varies in different gallons of gasoline blend
If 50/50 blend of E85 is still within the range
of what the stock system can manage
that is valuable news

I burn 85 octane. However, that is because I live in the Rockies and gasoline octane is lower here due to the alitude.
The thing that chaps my @$$ about that is they sell 85 octane for the same price that the rest of the country sells 87. 87 octane here is considered mid-grade and is sold for mid-grade price.
I am ok with the fact that because of the altitude 85 octane performs like 87 at lower altitudes, but it should be sold cheaper.

thanks,
that would be interesting
i guess that you have not had a
'Check Engine' light illuminate
while running 50/50 E85 blend in the past
maybe that is a rough indication
that the short and long fuel trims
available in the stock PCM computer
have been able in combination to adjust successfully
i would guess that if the oxygen sensors
can't stay near an average voltage of 0.5
the check engine light would eventually come on
very roughly
half of 14.7 (gasoline a/f ratio)
added to half of 9.0 (pure ethanol a/f ratio)
and divided by the original equipment setting of 14.7
is about 81%
so the Magnum V8 PCM computer
would have to adjust the stock fuel injectors to spray
at least 19% more
this article says 50/50 blend is possible on many modern EFI engines
