Best: Any GM 2.2L or 2.4L Ecotec. To get those few tablespoons of oil out of the canister housing, I lay a shop rag in there for 10 seconds and it's all gone.
Worst: Any Saturn 1.9L "S" series engine. The filter is at the rear of the engine, jammed up above the driveshaft. It can only be accessed with great difficulty and unnatural hand contortions.
