What size oil filter wrench will unscrew the on a 2001 Oldsmobile Intrigue?
The 2001 Oldsmobile Intrigue uses a cap-type oil filter, not a spin-on type that requires a wrench. Therefore, you don't need an oil filter wrench. You should be able to remove the filter by hand, though sometimes a filter cap remover tool (similar to a strap wrench) can be helpful if it's really stuck.
