E85 Boondoggle of the Day: E20, E30

We’ve pointed it out before: the ethanol industry has a cunning plan to breach the “blend wall” (a.k.a. the fact that American customers don’t want E85). While they’re waiting, hoping and praying for a Titanoboa cerrejonensi-sized gas price spike, they’re planning on using their political leverage to “offer” (i.e., force) motorists E20 and E30 ethanol blends. The big problem: it’s not entirely clear that engines like to run on those blends. (E85-compatible vehicles are, uh, E85-compatible). In fact, it’s pretty clear they don’t. But that’s not going to stop the lobby from trying . . .

“The U.S. Environmental Protection Agency has granted a testing exemption to Renergie Inc. Under the test program, the first of its kind in the U.S., Renergie will use variable blending pumps, not splash blending, to dispense hydrous ethanol blends of E10, E20, E30 and E85 to test vehicles. The testing could help determine blend optimization with respect to fuel economy, engine emissions and vehicle drivability. Vehicles will be involved in the test program which will last for a period of 15 months.”

And what, pray tell, is “splash blending?”

In the U.S., the primary method for blending ethanol into gasoline is splash blending. The ethanol is “splashed” into the gasoline either in a tanker truck or sometimes into a storage tank of a retail station. Renergie believes the inaccuracy and manipulation of splash blending may be eliminated by precisely blending the ethanol and unleaded gasoline at the point of consumption.

And if you eliminate the imprecision, then maybe, just maybe, E20 for everyone! By law! There’d be joy in cornville that day. And while lawn mower, snowmobile and jet ski owners contemplate that possibility, here’s a bit of scientific hype for those who still think food-into-fuel will save the planet. Or something.

Tests conducted in Europe have shown that the use of hydrous ethanol, which eliminates the need for the hydrous-to-anhydrous dehydration processing step, could mean energy savings of between ten percent and forty-five percent during processing, a four percent product volume increase, higher mileage per gallon, a cleaner engine interior and a reduction in greenhouse gas emissions.

    Anyways, they recommend some retailers that meet TOP TIER standards for gasoline quality and additives. For us Canucks, only Shell and Petro-Canada are on the list. No E10 providers on here, for ones in Calgary anyways I don't know about Alberta, but in Ontario, at Shell, 87 Octane "may contain up to 10% ethanol" while 89 "may contain up to 5%". 91 (which I feed my Saab) is explicitly labelled as ethanol-free

    @crackheadalley You came down here and rented a Chevy Asstra? Good choice. The engine is a 1960s GM engine with minor modifications. Drinks like there's no tomorrow, can't rev for s***, is noisy and shakes all over, low hp for the displacement. Torquey down low though and relatively reliable. So you fly 1000s of miles to another country and rent a Chevy. Probably ate at McDonald's too. What a way to see the world. FWIW, I live down here and don't have as superficial a vision as he does. I mean, I have to deal with this s*** everyday. There are available at Brazilian gas stations: Premium Gasoine : Higher octane stuff that only a Ferrari can fully appreciate Additivated (??) or maybe Special Gasoline: Comes with some cleansing chemicals that reportedly keep your engine cleaner. Common or Regular Gasoline : is just gasoline with no cleaning chemicals. E100 : 100% sugar cane juice, and as a rule of thumb, you have to multiply gas prices by 70% if the price of ethanol is lower, go for it, you lose in mileage, but the car gets some extra hp, burns cleaner (no sludge issues when using ethanol). BTW All gasoline in BRazil comes with, by law, 21 to 27% ethanol. This range is used to "control" price fluctuations. All said, I'd much rather burn dino juice all day long.

  • 3-On-The-Tree Alan, I was an Apache pilot and after my second back surgery I was medically boarded off of flying status due to vibrations, climbing on and off aircraft, so I was given the choice of getting out or re-branching so I switched to Military Intel. Yes your right if you can’t perform your out doesn’t matter if your at 17 years. Dad always said your just a number, he was a retired command master chief 25 years.
  • ToolGuy "Note that those vehicles are in direct competition with models Rivian sells"• I predict that we are about to hear why this statement may not be exactly true
  • ToolGuy From the relevant Haynes Repair Manual:"Caution: The 4.6L models require a special tool to extract the water pump from the coolant crossover housing. This special tool is expensive and the removal procedure is difficult. Have the water pump replaced by a dealer service department or other qualified automotive repair facility if the tool is not available."One version of the tool is Lisle 14440; I paid $10.82 (less 5% discount, plus shipping).You can see why I never attempt my own maintenance or repairs. 😉
  • Dave M. IMO this was the last of the solidly built MBs. Yes, they had the environmentally friendly disintegrating wiring harness, but besides that the mechanicals are pretty solid. I just bought my "forever" car (last new daily driver that'll ease me into retirement), but a 2015-16 E Class sedan is on my bucket list for future purchase. Beautiful design....
  • Rochester After years of self-driving being in the news, I still don't understand the psychology behind it. Not only don't I want this, but I find the idea absurd.
