The 50 ED95 buses had a cost of R$ 20 million (US$12.3 million) and due to the higher cost of the ED95 fuel and the lower energy content of ethanol as compared to diesel, one of the firms participating in the cooperation agreement, Raísen (a joint venture between Royal Dutch Shell and Cosan), supplies the fuel to the municipality at 70% of the ...
Other than the piston rings, “blow-by” gases can push the fuel oil past the rings and into the crankcase. [1] “Blow-by” gases are a mix of fuel oil and exhaust gases that push past the piston rings. Crankcase dilution is caused more when the lube oil is fresher. [3] Another cause of crankcase dilution is a slow or delayed injection ...
Compared to oil, with an 11:1 EROI, corn ethanol has a much lower EROI of 1.5:1, which, in turn, also provides less mileage per gallon compared to gasoline. [7] In the future, as technology advances and oil becomes less abundant, the process of milling may require less energy, resulting in an EROI closer to that of oil.
Companies import biofuel to the US, blend 1% or even 0.1% regular fuel, and then ship the blended fuel to Europe, where it can get a second subsidy. These blends are called B99 or B99.9 fuel. The practice is called "splash and dash.". The imported fuel may even come from Europe to the US, get 0.1% regular fuel, and then go back to Europe.
E85 is increasingly common in the United States, mainly in the Midwest where corn is a major crop and is the primary source material for ethanol-fuel production. As of July 1, 2014, there were more than 3,300 fuel stations that offered E85 fuel. [12] E85 as a fuel is widely used in Sweden; however, most of it is imported from Italy and Brazil.
However, in Brazil all vehicle manufacturers (Fiat, Ford, VW, GM, Toyota, Honda, Peugeot, Citroen and others) produce "flex-fuel" vehicles that can run on 100% Gasoline or 100% on Ethanol or any mix of Gasoline and ethanol [50]. These flex fuel cars represent 90% of the sales of personal vehicles in Brazil, in 2009.

If such a company buys a fuel swap and the price of fuel declines, the company will effectively be forced to pay an above-market rate for fuel. If the company buys a fuel call option and the price of fuel increases, the company will receive a return on the option that offsets their actual cost of fuel. If the company buys a fuel call option ...
