Some Experience Helpful
✅ The Cummins diesel is a bigger job than a gas engine — 12 quarts, diesel-specific oil, and a fuel/water separator that needs draining separately. Watch the full video before starting. Worth doing yourself — dealer charges $150-200 for this service.
⚠️ Important: The Cummins diesel holds 12 quarts and requires diesel-specific oil. Do NOT use regular gasoline engine oil.

🛢️ Oil Pal tip: At 12 quarts the Cummins is one of the largest drains you'll encounter — Oil Pal's 3.5-gallon capacity handles it perfectly. A flat drain pan absolutely will not work for this engine.
