Lets say, hypothetically of course, that you rolled your truck over. Mildly and gently, lets also say your truck sat that way with all four legs in the air for about 14 hours. Lets also say that hypothetically, before you were even settled on the roof you already had it in park and had killed the engine. Lets also say that it did leak all it's oil out of the oil filler cap while it was upside down. If you got your truck home, what would you need to check or do aside from putting more hypothetical oil in your hypothetically now right side up truck, before starting it? TIA.
