What is the International S13?
International describes the S13 as a 12.7 L inline-six diesel within the S13 Integrated Powertrain. The system combines engine, T14 transmission and dual-stage aftertreatment. The manufacturer lists it across highway and vocational applications; exact ratings and equipment remain vehicle-specific.
What matters in a comparison
Compare an S13 proposal as a complete system. Request the truck’s actual engine rating, transmission version, aftertreatment specification and application approval. Manufacturer fuel-economy comparisons have defined reference vehicles and conditions; use suitable operating evidence for your own budget. If comparing with an earlier International truck, include differences in acquisition price, warranty terms and service history without assuming the engine name captures them all.
Fluids & filters
International S13 Integrated Powertrain; serial-specific service lookup required.
Reference checked:
Identify the unit first
Use these details to match the manufacturer's application record before choosing a fluid or ordering a filter.
- Truck VIN
- Engine model and serial number
- Engine emissions/model year
- Installed filter-housing model and original part number
- Factory coolant label and subsequent coolant-change records
Filter numbers & cross-references
A catalogue cross-reference links part numbers. It does not confirm that either part fits every version of this model. Match the original part to the unit first, then check the replacement manufacturer's application and any supersession.
No application-specific filter number is verified here. Use the official identification and parts references below.

What still needs unit-specific confirmation
- The reviewed public International sources did not establish application-confirmed S13 oil/coolant specifications or filter part-number cross-references. Use International VIN-based service information and RepairLink/dealer parts lookup before selecting products.
- Do not substitute Scania DC13, International A26 or Cummins service parts based on related displacement, design or truck model.
- Filter quantities, capacities and intervals also require the VIN/engine-serial-specific manual.

Questions to take to the supplier
- Which model-year and vehicle-specific S13 specification applies?
- What T14 and auxiliary-power configuration is included?
- What evidence supports the operating assumptions?
