While ethanol producers have been lobbying to increase the blend of that alcohol in standard gasoline to 15%, many in the auto industry have opposed that increase, saying that it could damage cars. Now the U.S. Environmental Protection Agency has, for the first time, proposed reducing the ethanol requirement in the nation’s fuel supply. Actually, what they are proposing is a smaller increase in the overall use of ethanol, which means that the national standard may not be raised to E15. (Read More…)
I’m a long time lurker, first time asker. I was curious about the effects of E85/E90 ethanol laced gasoline. I have read a bunch about how older cars are susceptible to corrosion damage to various parts of the fuel line. (Read More…)
I have a problem and hope you can help me. My Cadillac Brougham with the 307 V8 smells like gas under the hood. This is intermittent and the last time it was in the shop the mechanic found no leaks under the car or around the carb. (Read More…)
Longtime reader, first time writer. I love reading your stuff, well worthwhile.
My query is about fuel additives, after-market specifically. I have used the Lucas Oil products and found them to produce a mile or two better MPG in my 94 D21 four banger. (Note: that’s a Nissan Hardbody – SM)
What is your take on additives? Have you found any others to be of significant value to the user/user’s vehicle?
A chicken could become as unreachable as caviar in many poor countries, warns a study of the OECD and the United Nations. Chicken is projected to rise in price by 30 percent in the next ten years – inflation adjusted. Other staple foods such as corn, sugar or cooking oil are seen rising in price by twenty percent. Why? On one side of the ledger is higher demand, mainly from China and India. On the other side: „Increasingly, the crop doesn’t end up in the pot, but as fuel in the tanks of cars,“ says the German magazine Der Spiegel. (Read More…)
TTAC has paid close attention to the fortunes of ethanol in the United States, where grossly wasteful subsidies have forced the corn-derived fuel into the fuel supply in growing percentages, drawing backlash from small but vocal portions of the population. But much of the ethanol ire is directed at higher blends like the recently-approved E15 and the increasingly-unpopular E85 mixtures. Meanwhile, most Americans regularly fill up their tanks with E10, which has become standard at pumps across the nation. But in Germany, where E10 was only just introduced, people are rejecting the low-ethanol blend that even the most vocal American ethanol opponents use every day. Initially, the biofuel industry in Germany blamed a lack of education for suspicion of E10, but according to Autobild, some 75 percent of German drivers now know whether their vehicle takes E10 (and most do)… but still, only 17 percent actually chose E10 for their last fill-up. And only 39 percent who know for a fact that their car can take E10 have ever used the ten-percent ethanol fuel. Why? Despite the high level of education, 52 percent of respondents still feared motor damage from the ethanol. Another 50 are opposed to “filling up with food.” Sometimes the more you know about something, the less you like it.
German motorists won an important battle against ethanol. They used a downright un-German tactic: Widespread insurrection. They simply won’t buy the stuff. An edict handed down from Brussels ordered that Super has to contain 10 percent of ethanol. An alliance from Germany’s ADAC autoclub to Greenpeace said the new gasoline is a work of the devil, it is liable to ruin cars, and the environment. That didn’t impress Brussels. But then, a buyer strike did set in. (Read More…)
Gasoline with up to ten percent ethanol have been approved for public sale in the US, and the ethanol industry has been pushing to increase the maximum allowed blend to 15 percent. Or 12 percent until the EPA can figure out if E15 damages engines. But with automakers turning against the e15 push, fears about E10-related engine damage (which primarily began with boat and small engine operators) are being more widely heard. So why is E10 allowed if it damages engines? For one thing, trailerboats.com points out that
Yamaha warns that due to the fungible nature of fuels in transit from refinery to service station, some E10 fuels may actually get an extra dose of ethanol
In other words, E10 may be safe but you may not actually be getting E10. But more importantly, the market is answering the call of consumers. Over at pure-gas.org, a site dedicated to connecting Americans with stations offering ethanol-free gasoline, the number of registered “pure gas” pumps has skyrocketed since June of last year. But, warns the site’s founder (a BMW motorcycle enthusiast),
We buy [ethanol-free gas] because we want to fuel our vehicles with it. If you want to save money on gas, this site is of no use to you – it will NOT have gasoline prices on it. They vary from day to day and this site isn’t about saving money. It’s about finding pure gasoline for your machine.
So we’re wondering: does ethanol-free gas exist near you, and if so, is it more expensive? Finally, is there a price premium you would be willing to pay for ethanol-free gas? Or would you even pick corn-free gas (and its groundwater-accumulating carcinogen MTBE) at price parity with E10?
Well, the good news is that the EPA has thus far refused to allow gasoline blends of more than ten percent ethanol. The bad news is that the Agency has yet to take a firm stand against the idea of eventually allowing E15 into the nation’s gas pumps. In fact, as the EPA’s response to the ethanol lobbying group Growth Energy’s request to allow E15 [full document in PDF form here] opens:
It is vitally important that the country increase the use of renewable fuels. To meet that goal EPA is working to implement the long-term renewable fuels mandate of 36 billion gallons by 2022. To achieve the renewable fuel requirements in future years, it is clear that ethanol will need to be blended into gasoline at levels greater than the current limit of 10 percent.
The EPA is set to rule as soon as tomorrow on the so-called “blend cap,” which forbids the sale of gasoline with more than ten percent ethanol. The petition to raise the blend cap came from a relatively new pro-ethanol lobbying group, Growth Energy, which requested the cap be moved to fifteen percent ethanol. Growth Energy’s request cites foreign oil dependence, “green-collar jobs” and the future of cellulosic ethanol as reasons to bump the blend cap, but as the New York Times reports, the real problem is that the ten percent limit is bumping up against a congressional mandate to blend 15b gallons of biofuels with gasoline by 2012. What the Times fails to mention is the financial incentive for raising the blend cap: the 51 cent-per-gallon of ethanol blended tax credit. In 2007, when gas consumption was at an all-time high and ethanol blending mandates required a mere 4.7b gallons (with 7b actually blended), that credit cost taxpayers nearly $3b. In 2012, when the mandate hits 15b gallons, the taxpayer tab will be closer to $7.65b.
