Stick Lifters I've always used about a 1/4 quart of ATF added to the existing oil then drive till next oil change. Been doing this for over 30 years on customers and my personal cars to free up stick lifters. Also use Castrol motor oil as its a captive oil (holds onto particulate mater and puts it in the filter) Unlike Quakerstate and pensoil that pushes the fine particles off to the side and then runs down into the oil pan.
