Did you know that black folks from africa are the only pure homo sapeins?
All human DNA outside of africa is flavored with some Neanderthal DNA picked up in Europe or Asia

And this fact points to the validity and accuracy of clay tablets in cunnieform unearthed in southern mesopotamia written by the sumarians roughly 8000 bc regarding homo sapien origins.
Along with them also having our entire solar system mapped including planets that we didnt "discover" till the 20th century....makes ya wonder.

The reason your mileage dropped is that an engine requires a bit over 20% more fuel when running straight alcohol vs straight gas.
Now ethanol is added at a 10 % mix to gasoline so you dont lose 20% in mileage...its more like a 3% loss.
Now flex fuel engines are made to run on gas gas ethanol or e85...they make these engines accomodate the different fuels and volumes by altering ignition timing based upon info supplied to the ecm through various sensors.
It gets interesting building perf engines if you can get the 85% alcohol fuel.
Most engines on pump gas today cannot be streched much passed 9.5 to 1 compression.
I built an engine about 5 years ago with 12.5 to 1 compression and we were able to run about 38 degrees total advance on the ignition on pump e85
The difference between the to 383 chevy's in my rear engine car was almost 2 seconds in a quarter and i think if i tweaked the fuel and timing some more it may have gotten closer to 3.
Problem is e85 is plentiful in the cornbelt but not so much anywhere else.

E85 is great for forced induction engines with the right engine management systems. As a mandated fuel it sucks balls. Two different things.

My mileage improved with the 100% gas. It dropped to the usual with the standard 10% ethanol blend.
Now my Tahoe is pretty damn poor at discerning E85 from the standard blend of 10% ethanol. Ive had the alcohol sensor reset once already and i discovered it was due to mixing the fuel. So say i bought a full tank of E85 and ran it down to 1/4 then fueled up with a tank of the standard 10% mix. Now it doesnt know how to compute and returns a big fuck you back to me in the form of single digit mpg numbers. Due to improper alcohol content calculations. It then has to be reset at a dealer. Awesome right?!? Not. You can thank @Kakarot for that bit of knowledge. He learned and forgot more than most ever knew about GM pushrods engines.

My ford doesnt care. Regular gas, E85, blood, fuckin midget tears...it burns it all. Doesnt set me back a moment. Gotta love it

Im supposing your referring to the new trend of direct injection engines being used by Toyota, Ford and GM?
Toyota has utilized direct injection in their 5.7L since 2007. Ford has utilized direct injection in their ecoboost engines since 2011. And now GM is using it in the new 5.3L.

Kind of like a diesel. Highly pressurized fuel via a common rail. Higher compression

I can tell you this. There are what's called shippers. These are the companies with the money that buy and sell the gas. They hire the carrier who transports the fuel from what we call the racks (where we the carriers load our trucks) and bring to the stations. A lot of the racks (like chevron, conoco, tesoro, etc, etc) have tanks with additive for certain blends. So, i can go load costco fuel (which has to be thier proprietary blend) at a chevron refinery or a tesoro refinery or kinder morgan, etc, etc. When the numbers are punched in to load the truck for a certain branded station it will load thier blend. I can be at kinder morgan and on the lane at a rack and choose chevron, tesoro, shell, costco, etc, etc.

Yeah, fuel is a commodity bought and sold in bulk. The additives and detergents are special to each individual brand of gas. Added at the time of transportation. No other generic brand of fuel can use a prepared blend owned by another company. And i will add all gas has detergents added to it but only ones meeting the Top Tier can be included in the group. The other is just cheap fuel.

Nothing about apes. Just humans and how most of us have up to 2 percent Neanderthal dna.
Just some interesting genetic history.
We all come from the same genetics... and pick up some interesting diversity as we spread out and 10s of thousands of years go by.

Did you know that black folks from africa are the only pure homo sapeins?

Science would say Neanderthal is the origins of humanity. Wouldnt they?
Or the primordial soup explanation. Which is so commical it gives me explosive diarrhea just thinking about our best and brightest actually pit their seal of approval on THAT!
So im struggling with this "pure" thing.
It seems it would indicate some thing else...

Oil Company Offers $50M in College Scholarships for Arkansas Town

So Murphy gas a major supplier for Walmart and Sams Club locations put up $50 million over the next 20 yrs to fund their home town Arkansas HS graduates to attend college! I guess the catch is if you went K-12 in the town your elligible for the whole amount. If you attended only 4yrs of HS there you get 65%. If less than 4 yrs you get nothing. Pretty damn cool.

But the scholarships are capped at Arkansas highest resident tuition rate(currently). Back in 2007 when this was introduced that rate was $6,010. That seems really low?

Nope

Forced induction is boosting air - turbo or supercharger.

The E85 helps keep IATs lower which let's you sustain more boost before knocking = more power.

And no, direct injection is nothing like a diesel. Totally different technologies. Direct injection was a German WWII invention, first used in cars in the MB 300SL in the 50S. All fuel injected cars have pressurized fuel, most in common rails, at least the ones after the 70s or so. US cars have of course sucked balls in the FI department as well.

The ecoboost is a twin turbo direct injection engine that still uses spark plugs. All direct injection engines have to be made to handle higher compression. Most direct injection engines are diesel which is the comparison i was using. Which is why i brought up the fact its being used in gas engines now. Which is not the norm here domestically. A common rail is used in diesels not gas engines. Fuel injectors are. At a much lower pressure. I guess common rail direct injection engines produce a leaner burn which allows for WAY more HP numbers even in small displacement engines. Case in point, the Ford Ecoboost which pulls 375hp and 470 lb ft tq at a low 2500 rpm out of a small twin turbo 3.5L v6. Making it the most powerful in its class, by far. Even the bigger v8's. The performance edition in the Raptor is even more powerful. Which won the Baja 500 in stock form. Im wondering if this is the future for American vehicles to meet the govt mandated CAFE mpg standards? More power, less fuel.

Kinda the other way around - higher compression requires more precise fuel injection which direct injection delivers. There's also the emissions angle.

I don't deal with obsolete technology much, as I mention, Mercedes had this in a car in the 50s. US mfg rely on old stuff for too long.

In any case, nice to be rid of carburetors.

Don't know about Mercedes but gm started direct injection (injector in combustion chamber as opposed to intake) with their trucks in 2014. It in itself isn't bad but combine it with the valve overlap from vvt to reduce emissions (that's why theirs no egr valve anymore) and you end up with tons of carbon buildup on the intake valves that no amount of top tier gas or treatment can reach because fuel doesn't go past the intake valves anymore due to direct injection.

 

[gr8whitetrukker]

Toyota and Ford have been doing it successfully.
Wonder what gives?(scratches head)

Interesting - I wasn't aware of buildup on intake valves. Would that be the case mainly with intermittent driving, or does it burn off once the engine hits a certain load/temp for sufficient period of time? Kind of like how you boil off water (condensation) in the engine oil after ca 20-30 minutes of driving (depending on load etc).

Mercedes rolled this out in the 90s - and common fuel rails go back further than that, although the PSI ratings were obviously nothing like direct injection systems. Fairly basic MBs from the 1960s (with mechanical fuel pump injector systems) had fuel pressures over 200 PSI - not much compared to direct injection fuel systems, but a hell of a lot more than their carburetted competition of the day.

BTW, EGR is such BS - why fuck up the ENTIRE engine just to fret over emissions during the first 45 seconds? Liberals and their boondoggles.

Twas emissions that killed the beast. Doesn't really burn off..ever, just sits there and restricts air flow or it finally drops down and causes the valve to stick long enough to get too friendly with the piston. I'll see if I have a pic of it from the topside.
