List Of Oil & Gas ETFs
http://etfdb.com/etfdb-category/oil-gas/
The oil futures contract is /CL, and the mini contract is /QM, but a leveraged position in a commodity is probably not an "investment."
There are mutual funds and ETFs that can be purchased with as little as $3k.
See Fidelity and Vanguard funds for lower costs.
Buy XOM, CVX, COP or similar stock.
