We all know tat now fuel prices are boomin, well there are alternative ways to save cash.
Like if u want a straight foward way buy a hybrid like Toyota Pruis or Honda Insight.
If u dont wanna spend money on a new car go convert it to LPG(Liquid Petroluem Gas)
u can also run ur diesel cars like Chia Yoong Jia father's ford ranger on ur house cooking oil or oil from KFC(I am not Kidding X_X)but u need a better filter
