Might be a good time to stockpile some oil, especially for the cars. Prices will go nowhere but up, esp if the Arabs act up and the Suez is closed.
If you really want to save money, buy it in the 5 qt jugs like they sell in Wal Mart. Divided by five, the cost per quart is considerably less than the single bottle price.
I was looking at Valvoline Maxlife for the Toyota, and it was $4 and change per quart, but the 5 qt jug was $13.00. Castrol was similar savings.
Stockpiling gas is riskier. besides being more dangerous, it doesn't hold up as well with the ethanol in it.
