Some information is missing.

The engine has 1 1/4 gallons of oil in it now? And the question is how much more oil is needed to fill to capacity (full).

What is the capacity of oil in the engine?
Oh oops. if there are 3 quarts of oil in the engine now, how many more quarts...
1 gallon = 4 quarts
try it now.
13 quarts?
Needs two more quarts?? I feel this is right
