The abstract: Application number: 20070119095
Abstract: The present invention is a hybrid diesel fuel and method of manufacture. The fuel composes a petroleum diesel fuel mixed into a biosynthetic waste or virgin oil and further containing a stabilizer. The hybrid fuel consists essentially of about 10% to 50% of Diesel Number 1, Diesel Number 2, or Farm Diesel petroleum fuels, and up to 90% filtered and polished biosynthetic oil, measured by volume. The biosynthetic oil can contain all levels of common commercial vegetable and animal fats in any ratio. The hybrid fuel also contains up to about 0.17% stabilizer, which further contains cetane boosters, cleaning agents to remove deposits from the fuel system, a lubricant, demulsifiers, and anti-gelling agents. The invention functions as biocide to inhibit bacterial growth. The invention is substantially equivalent to Diesel Number 2 in terms of power and engine speed, but is cleaner burning and considerably less costly.
