"small "truck boxes" from sears - the are basically plastic tool boxes and some large enough to store 2 quarts of oil (very handy to keep the oil "contained")"

I found a product called Oil Safe after I had an oil container leak all over my Jeep. Luckily I didn't have carpet in my old CJ7 but it was still a pain to clean up.

A little pricey but compared to cleaning up a spilled quart of oil, it seems worth it.
