Exotic fuel blends were banned after Agip's success in 1991.

But did you know that more than 20 different "boutique fuel blends" are sold from June to September?

Some Indian taxis and auto-rickshaws run on adulterated fuel blends.

Secondly, we also need to confront the larger problem of too many localized fuel blends, which are called boutique fuels.

Differing fuel blends will also affect fuel economy.

High alcohol fuel blends are reputed to cause corrosion of aluminum fuel system components.

Research shows that cineole-based eucalyptus oil (5% of mixture) prevents the separation problem with ethanol and petrol fuel blends.

Engine warranty concerns also came into play in a recent effort to create labeling requirements for diesel fuels containing renewable fuel blends.

Newer monopropellants include nitrous oxide fuel blends.

All in all, Formula One teams use about 50 different fuel blends, tuned for different tracks or conditions, in a typical season.

Nitrous Oxide Fuel Blend propellants are a class of liquid rocket propellants.

They can also use fuel blends derived in part from huge existing stockpiles of weapons-grade plutonium and uranium, thereby beating our swords into plowshares.

ASTM International has approved a new specification for diesel fuel blends containing 6%-20% biodiesel.

Considering those comments, the FTC decided to set separate labeling requirements for biodiesel blends and biomass-based diesel fuel blends.

Clean Cities performs these duties through a network of more than 80 offices that develop public/private partnerships to promote alternative fuels, advanced vehicles, fuel blends, hybrid vehicles, and idle reduction.

Ethanol promoters contend that automotive manufacturers currently fail to equal the fuel economy of gasoline because they fail to take advantages of characteristics which are superior in ethanol-based fuel blends.

"While the drop in exports has made it more economical for processors like Archer-Daniels-Midland to convert more corn into ethanol fuel blends, it has also reduced costs for poultry," he said.

His work was such that he was invited to develop the fuels used in the UK's Schneider Trophy entrants, his fuel blends contributing to the success of the British entries in 1929 and 1931.

One thing, in particular, that drives gas costs is the growing number of different fuel blends - or boutique fuels - in the United States since the implementation of the Clean Air Act Amendments of 1990.

The Clean Cities program partners with more than 80 volunteer organizations throughout the United States, developing public-private partnerships that promote alternative fuels and advanced vehicles, fuel blends, fuel economy, hybrid vehicles, and idle reduction.

During the period when teams were limited to a specific volume of fuel during a race, exotic high-density fuel blends were used which were actually heavier than water, since the energy content of a fuel depends on its mass density.

A consortium consisting of Boeing, NASA's Glenn Research Center, MTU Aero Engines (Germany), and the US Air Force Research Laboratory is working on development of jet fuel blends containing a substantial percentage of biofuel.

One note of CAUTION, if you are the owner of an early model Safari 28, the fuel tank was made of fiberglass, (Coast Guard Requirements changed this sometime in the 1970s to require a metal tank) and fiberglass can degrade with modern gasoline fuel blends.

Alcohol (particularly methanol) fuel blends were expected to cause chemical damage to fuel system materials not designed to withstand exposure to alcohols, to increase water contamination due to alcohols' co-solvent properties, and via alcohols' solvent action loosening fixed fuel system deposits thus causing free-moving particulate contamination and clogging of various components.
