Utilization of used cooking oil and used motor oil as an alternative fuel source.Researchers have experimented with finding an alternative fuel source. This proposed study was to further the researcher's investigations. The purpose of this study was to determine if used cooking oil and used motor oil blended together could be used an alternative fuel source. In this experiment the blends were compared to used and pure motor oil. It was hypothesized that the used cooking oil and used motor oil blends could be used as an alternative fuel source that would have the least negative impact on the environment. The methods that were used were regular American Standard Testing Method (ASTM ASTM abbr. American Society for Testing and Materials ) Procedures. The tests that were conducted included the calorific value calorific value n. The calories or thermal units contained in one unit of a substance and released when the substance is burned. (Btu test), the flashpoint, the density, the sulfur content, the viscosity, and the metals test (Arsenic arsenic (är`sənĭk), a semimetallic chemical element; symbol As; at. no. 33; at. wt. 74.9216; m.p. 817°C; (at 28 atmospheres pressure); sublimation point 613°C;; sp. gr. (stable form) 5.73; valence −3, 0, +3, or +5. , cadmium cadmium (kăd`mēəm) [from cadmia, Lat. for calamine, with which cadmium is found associated], metallic chemical element; symbol Cd; at. no. 48; at. wt. 112.41; m.p. 321°C;; b.p. 765°C;; sp. gr. 8. , chromium chromium (krō`mēəm) [Gr.,=color], metallic chemical element; symbol Cr; at. no. 24; at. wt. 51.996; m.p. about 1,857°C;; b.p. 2,672°C;; sp. gr. about 7.2 at 20°C;; valence +2, +3, +6. , nickel and lead) The results of these tests prove that the hypothesis was correct. The oil blends could be used as an alternative fuel source. The flashpoint of the oil blends was greater than 190.89 degrees Celsius while the flashpoint of the used motor oil itself averaged about 177 degrees Celsius. The BTU value of the blends were on average 17454.051b, while the used motor oil's BTU value was 18466. The viscosity test showed that the oil blends didn't solidify so·lid·i·fy v. so·lid·i·fied, so·lid·i·fy·ing, so·lid·i·fies v.tr. 1. To make solid, compact, or hard. 2. To make strong or united. v.intr. , but the used cooking oil did solidify by itself at four degrees Celsius. The Sulfur content of the blends was on average .281. The used coking oil itself has less than .02 sulfur, whole most of the blends content of sulfur came from the used motor oil itself. These results support my hypothesis and prove that the oil blends can be used an alternative fuel source. Keywords: Used cooking oil, oil blends, used motor oil, alternative fuel.
