29 quarts
It takes 15 quarts of 15W40 diesel oil I highly recommend Rotella 15W40
The oil capacity for International 4300 dt466 from 1994 to current hold 30 quarts with filter. Those made before 1994 have smaller engines with the capacity to hold less oil.
Depends on what engine it has. IIRC, that model could be had with the DT466, DT530, Cummins 6BT, Cat 3116, or Cat 3126 engine.
2.1 Quarts
5 quarts
If I remember correctly, I believe oil capacity is 32 qts.
10 quarts
54.2 liters
7 gallons (28 quarts)
Need to know what engine it has in order to answer this.
At servicing/oil change I use approximately 6 litres of engine oil
