Most often diesel engines (I used to be an auto mechanic). Even passenger car diesels can take 10+ quarts. Gas engines typically take less oil but big engines can still take 5-7+.

That's 11.3L for the civilised audience.

For reference, my 3.6L 6-cyl boxer needs about 6.5L according to my service notes.

Patriots love their big trucks. More oil = owning the lib vegans.

2018+ Ford Mustang V8 for one.

GM V8's take 8 quarts

The 3L diesel in my car takes about 8qt per change. The 5.9L diesel in my truck takes 12qt.

Air cooled 911 :)

Older Porsche 911s take about 11 quarts.

most of V8 engines need 10+ quarts

Diesel trucks. My Ram 1500 with the 5.7 Hemi takes 7 qt. The 5.9 Cummins in my Ram 2500 takes 12 qts.

Cessnas.

Most v8s.
