Short answer
API CI-4 and ACEA E7: what a fleet must check
API CI-4 and ACEA E7 are performance categories from different classification systems, not blanket approvals for every diesel vehicle. Match each engine, emissions system, OEM requirement and drain interval to the exact product TDS before consolidating a fleet oil.
Keep API, ACEA and OEM requirements separate
API and ACEA use different category systems and test frameworks. A product can list both, but one category does not translate automatically into the other and neither replaces a vehicle-maker requirement.
Read the full wording in the TDS for the exact product. Do not transfer categories from a historic or similarly named lubricant to an active product record.
Build a requirement matrix for the fleet
Group vehicles by engine family, model year, emissions stage, after-treatment hardware and the oil requirement in the manual. Record DPF, SCR and EGR configuration rather than assuming it from the age of the vehicle.
A mixed fleet may contain exceptions that prevent a single-oil policy. Those exceptions should be visible before procurement, not discovered after delivery.
- engine or vehicle model and year;
- emissions stage and DPF, SCR or EGR equipment;
- SAE, API, ACEA and OEM requirements;
- approved service or drain interval;
- exact product, TDS version and technical reviewer.
Link every decision to current evidence
Use the exact MOEVE product record and its current TDS as the evidence pair. If the necessary document or wording is missing, mark the match as unresolved and request verification instead of filling the gap from a price list or product name.
Confirm quantity, packaging, stock, destination and delivery separately in the enquiry. Commercial availability does not establish technical compatibility.
Frequently asked questions
Frequently asked questions
No. They are categories from different systems. Use the exact combination and OEM requirements stated for the engine and product.
Are these categories enough for a truck with DPF?No. Check the after-treatment requirements, ash-related limits, OEM specification and exact TDS for that engine and service regime.
Can one oil cover the entire fleet?Only if the documented requirements of every included engine overlap and a technical reviewer accepts the exact product evidence. Otherwise keep the exceptions separate.
Limitations
Limitations
- This guide does not approve a product for a truck, engine family or drain interval.
- Fleet consolidation requires current equipment data and technical review; a category name alone is insufficient.
