Final answer:
Initial fill quantities for engine oil vary by engine type and size. A 4-cylinder engine typically needs 4-5 quarts, a 6-cylinder 5-6 quarts, an 8-cylinder 5-8 quarts, and large engines like the Cadillac Northstar or diesel trucks can require 7-15+ quarts.
Step-by-step explanation:
The initial fill quantities for engines can vary depending on the specific engine design, size, and whether they are designed for cars or heavy-duty vehicles like diesel trucks. The question seems to be asking about oil fill quantities rather than fuel capacities. Engine oil capacities generally increase with the number of cylinders and displacement size, but for specific values, you should consult the vehicle's owner's manual or a service manual for exact specifications.
Giving a general reference without exact numbers: A 4-cylinder engine typically holds between 4 to 5 quarts (3.8 to 4.7 liters) of oil. A 6-cylinder engine might require about 5 to 6 quarts (4.7 to 5.7 liters). An 8-cylinder engine might hold 5 to 8 quarts (4.7 to 7.6 liters). For engines like the Cadillac Northstar, Olds Aurora, or in the case of larger diesel trucks, the fill quantities could be anywhere from 7 to over 15 quarts (6.6 to 14+ liters) due to their larger size and oil capacity requirements.
