Another critical oil system component is the oil pan. This part, made by Stef's, is designed to fit under a stock Buick chassis and will aid in oil control. Kent will use Fuel Safe foam, designed to eliminate sloshing inside gasoline fuel cells, to control windage. While we've not heard of this method previously, we intend to ask Fuel Safe how they feel about it. It sure seems like a budget way to thoroughly control oil, but is it a long-term mod? We doubt it, but it should be fine for the Challenge testing.
