half tank per time? |
find a job in EXXON, and you'll get a discount gas card. |
Too late. It is not easy to find a job in Exxon if your major is not petro-chemical engineering... |
If the gas price drop is linear, then it should make no difference by adding half tank or full tank gas each time.... |
down, you should short sell oil related stocks, such as USO. Or buy put options, or sell naked call options. Other methods can only save small amount of money. |
