I'm assuming you mean 12.7 Detroit Diesel 60 Series engine? IIRC, it's 11 gallons.
That depends on what the motor is.
Depends on what motor it has.
11 gallons with filter
Unless you have a 4x4 or 6x6 unit, there is no front differential.
The oil capacity on a 1993 Nissan Altima is approximately 4.1 quarts. The oil that should be used is 5W-30.
The engine oil capacity of a 1993 Toyota Camry V6 is 4.3 quarts.
Depends on which engine it has in it. For that MY, you might have a Cummins 6BT, 3116 Cat, 3126 Cat...
Oil capacity depends on the size of the oil pan in the truck and what type motor it has... My Freightliner with a Detroit had 11 gallons (they range as low as 9)
4.5 quarts
6 quarts
With filter the capacity is 4.6 quarts.
4.5 quarts if you are also replacing the oil filter.
