A four neck flask of 2 L was charged with 1000 g of the same longifolene as in Production Example 4 and 100 g of bromoacetic acid to carry out reaction at 170° C. for 18 hours. This reaction mixture was washed with a saturated sodium hydrogencarbonate aqueous solution and water and refined by distillation, and after refined by distillation, it was charged into an autoclave of 2 L together with 18 g of a palladium-carbon catalyst for hydrogenation to carry out hydrogenation (hydrogen pressure: 6 MPa·G, reaction temperature: 100° C., reaction time: 2 hours). After finishing the reaction, the catalyst was separated by filtration, and the filtrate was precisely distilled to thereby obtain 200 g of targeted 2-isopropyl-1,7a-dimethyl-octahydro-1,4-methano-indene (synthetic oil II: fluid C). The measurement results of general properties and a traction coefficient of the fluid C are shown in Table 4.
