Oil pan Gasket

I think I may have a leaky oil pan gasket. My car leaks about 1TBsp of oil a night and it seems to leak more if I dirve at highway speeds.
I am going to raise my car and use foot powder to locate the leak, but I feel it is my oil pan gasket.

I found a how to guide on autozone's website. If you have a minute to review it or just some good advice, I would like to hear your thoughts. Thanks.
