BRAP, I posted a shot of the box with the Top Sider. It's a marine product made by "TEMPO". It holds 5 qts, so you do have to empty it once, but its really a painless process. Since you're not changing your oil as frequently as i would with a 4/5 qrt engine, its not that much of a hassle. Its worked for me for the past 4 years so pretty happy with the process.
