Default I put in 7 with an oil change

For an oil change I start with 7 quarts... it shows about 6 1/3 on the dipstick; then add a quart when it drops to around 5.

Generally, it seems to take around 15-20 hours for the first quart then around 10 for the second and third... then, it's about time for the next change.

I am averaging 40 tach hours between changes.
