_____________ determination is not a very significant and important test for gasoline?
Correct answer: B. Viscosity
- A. Gum & sulphur content
- B. Viscosity
- C. Octane number
- D. Reid vapor pressure
Explanation
Gasoline viscosity is relatively unimportant because it is already a low-viscosity fuel and is not normally used as its principal quality specification. Octane number, vapour pressure, gum, and sulphur are much more significant performance or handling tests.
