CK-4 vs. FA-4 — the warranty-and-backward-compatibility split
- API CK-4 is fully backward-compatible to CJ-4 / CI-4 Plus / CI-4 / CH-4. Runs in all current and most pre-2017 engines. HTHS ≥ 3.5 cP. Standard SAE 15W-40 / 10W-30 / 5W-40.
- API FA-4 is intended only for EPA-2017+ engines that specifically call for it (Detroit DFS 93K223, Mack EOS-5, Volvo VDS-5, Cummins CES 20087, Renault RLD-5). HTHS reduced to 2.9–3.2 cP for ~1% fuel economy. Not backward compatible — do not put DURON Advanced in any pre-2017 engine, or in a 2017+ engine whose OEM did not explicitly approve FA-4.
- The Nov 2025 EOS-5 / VDS-5 approval applies only to DURON Advanced 5W-30, not the 10W-30 grade. When sizing FA-4 inventory for a customer running newer Mack MP8 or Volvo D13TC, lead with 5W-30.
Critical fleet implications
PACCAR (Kenworth, Peterbilt — MX-13, MX-11)
PCL holds no formal PACCAR engine-oil approval letter. PACCAR does not run a lubricant approval letter program. PACCAR's service requirement (per paccarpowertrain.com MX engine oil specs) is API CK-4 / FA-4 by category, plus Cummins CES 20086 for X15 power options.
DURON HP / SHP / UHP satisfy this on category compliance. The dealer-counter warranty conversation should reference API CK-4 + CES 20086 (for Cummins X15 variants), not a non-existent "PACCAR-approved" claim. This is industry-standard and not a PCL deficiency, but it has to be documented carefully for fleet managers who default to assuming an approval letter exists.
Cummins X15 EPA 2017 — the extended-drain caveat
Cummins' Quick Reference Guide for X15 (Bulletin 5410641) states verbatim: "DO NOT EXTEND Oil Drain Intervals with synthetic or semi-synthetic oils."
This is widely interpreted as Cummins protecting their own oil-analysis-driven drain-extension program — not as DURON UHP being unsuitable for X15 (it is CES 20086 approved). The practical rule: extend X15 drains only under Lube 360 + Cummins fleet-engineer concurrence. See op-pcl-extended-drain-evidence for the broader extended-drain discipline.
Volvo D11/D13/D13TC — ODI differential between Volvo-branded and other-Volvo-approved oil
Volvo Trucks' published Service at a Glance maintenance poster for 2017–2020 VNL/VNR/VNX/VHD/VAH (volvotrucks.us) defines two ODI tiers for D11/D13 with the 42 L / 44 qt oil pan:
- Volvo Premium Motor Oil (Volvo-branded) VDS-4.5: 60,000 mi / 95,000 km normal duty
- Other Volvo-Approved VDS-4.5 (the category DURON SHP / UHP occupy): 55,000 mi / 90,000 km normal duty
Use the lower figure when sizing PM schedules for B&J customers running DURON on Volvo D-series.
Detroit DD15 (EPA 2017)
DURON HP / SHP / UHP approved for DFS 93K222; the FA-4 alternative is DURON Advanced 5W-30 or 10W-30 against DFS 93K223. Daimler has the broadest backward acceptance of FA-4 — approved for use in 2010-onward DD-series engines.
Western Star / Freightliner
Daimler Trucks NA brands — same DFS 93K222/93K223 framework.
International / Navistar A26 (now part of TRATON)
DURON has no Navistar MPAPS B-6839 or T-11 approval listed. Warranty coverage relies on API CK-4 / SN category compliance. PCL has a commercial distribution agreement with International Truck Canada but no spec-level approval letter.
DURON HP-DRIVE — flagged
"DURON HP-DRIVE" does not appear on current PCL brand pages. May be legacy, regional, or rebranded. Do not publish this SKU on a customer-facing page; confirm with PCL technical rep before referencing.
DURON SHP grade scope correction
DURON SHP is supplied in 10W-30 and 15W-40 in NA. SHP 0W-40 and 5W-40 are not current SKUs in the SHP line — those viscosities live in the DURON UHP synthetic line. The source research had this miscoded; corrected here.
Trigger to revise
- PCL publishes a formal PACCAR engine-oil approval letter (currently none — would be material).
- Mack/Volvo extends EOS-5/VDS-5 approval to DURON Advanced 10W-30 (currently only 5W-30 is listed).
- ILSAC GF-7 first-licensing during 2026 — would affect the SUPREME passenger-car line on the light-truck side.
- Any DURON SKU label change visible on petrocanadalubricants.com.

Frequently asked questions
What is the difference between CK-4 and FA-4 diesel engine oils?
CK-4 is backward-compatible with CJ-4 / CI-4 — safe for older Class 8 engines and the mainstream over-the-road fleet position. FA-4 is a lower-HTHS-viscosity grade designed for fuel-economy and CO₂-compliant 2017+ on-highway engines only; it is NOT backward-compatible. Putting FA-4 in a pre-2017 engine voids the OEM warranty. Fleets running mixed-vintage tractors should standardize on CK-4 to avoid the cross-fleet mistake.
Does DURON have formal PACCAR approval?
The DURON line carries broad OEM approvals across most North American Class 8 engine OEMs (Cummins, Detroit Diesel, Volvo, Mack), but PACCAR has historically been the slowest to grant formal approval on third-party CK-4 oils. The matrix flags PACCAR cells specifically — fleets with PACCAR engines under active warranty should confirm the current DURON SKU's PACCAR status before standardizing.
What containers does DURON ship in for fleet customers?
Bulk delivery, totes (1,000 L IBC), 205 L drums, and 18.9 L pails — the standard PCL fleet container set. Mainstream over-the-road fleets standardize on bulk or tote with shop dispensing; smaller mixed-fleet operations use drums and pails. Per-litre premium scales accordingly.
