I too have one. The "special" tool is available at Autozone, Pep Boys, et al. A strap wrench works too.

Are you sucking the oil through the dip stick as recommended? I kind of like the whole arrangement. I just might install white shag carpet in my garage.

Start with 71/2 quarts and check your stick after starting the engine to circulate then shut down, wait awhile and recheck. Your dipstick range is two quarts.
