How often shoud I change my car's oil?

Austin Amarka has made a lot of different incarnations on the Phil Hendrie Show. In one bit, he was a construction worker specializing in cabinets and can lights. He's an advocate of a conservation program called "Hunt and Release" (as opposed to the catch and release program from the sport of fishing) whereby a hunter just wounds the deer, then takes it to a veternarian to have the bullet or arrow removed and then releases it back into the wild. He also enjoys the extreme sport of putting on a bulletproof vest, then donning a deer suit and running around in the forest so hunters can shoot at him. A brusque arch-conservative, Amarka runs "Don't Mess With Texas", a fanatical pro-death penalty organization which holds fiestas and chili cookoffs when convicted murderers are executed in the Lone Star State. He was even once a death row inmate who tried feigning mental retardation to escape the chair. Austin is a 'white nationalist' but lately has been having second thoughts about the superiority of caucasians since a black gentleman beat him so badly at a Scrabble tournament. Austin now owns a service station in Lancaster, California. Austin is one of Phil's more versatile and diverse characters, making his precise identity difficult to describe (as it often changes depending on the bit).
