How much lube can I take in my carry-on?

Under the TSA's 3-1-1 rule, each container must be 3.4 oz (100 ml) or less, and all your liquids, gels and creams must fit in one quart-size clear bag. Many other countries use a similar 100 ml limit. Larger bottles can go in checked luggage. Because pressure changes can cause leaks, seal lube in a zip-top bag either way.
