All of the following statements are true EXCEPT:
A) LPG tends to settle out as a liquid in the intake manifold.
B) LPG has a higher octane; therefore, it can be used in engines with higher compression ratios.
C) less frequent oil change intervals are required because LPG is a dry gas so it does not create carbon in the combustion chamber.
D) LPG burns cleanly, produces fewer emissions, and lacks the objectionable exhaust odor of incompletely burned gasoline.

Question

Quizplus · Accepted Answer

LPG (Liquefied Petroleum Gas) is a gas at atmospheric pressure and ambient temperatures, so when it enters the intake manifold, it expands and vaporizes rather than settling out as a liquid. The other statements about LPG's higher octane rating, less frequent oil changes due to its clean burning nature, and fewer emissions with less odor are true.
