What is the difference between API CK-4 and CI-4?

CK-4 is the current heavy-duty diesel category and is designed for engines with diesel particulate filters and selective catalytic reduction. CI-4 is an older category for engines without those systems. A CK-4 oil can generally be used where CI-4 was specified; the reverse is not true for a modern engine.

Heavy Duty Diesel Engine Oil in the UAE & Oman

How to choose a heavy duty diesel engine oil.

Heavy duty diesel engine oil is made for the diesel engines in trucks, buses, pick-ups, construction and mining machines, generators and marine auxiliaries. It carries more detergent and dispersant than a passenger car oil, to hold soot in suspension over long drain intervals, and it is specified to API CK-4, CJ-4, CI-4 or ACEA E grades and to the engine makers' own approvals.

LUBE-tech supplies heavy duty diesel oils from FUCHS TITAN, TotalEnergies Rubia, Mobil Delvac and ADNOC in Dubai and across the UAE and Oman, in 20 L pails, 205 L drums and bulk for fleets.

Picking the right grade

The API or ACEA category: A Euro 5 or Euro 6 engine with a diesel particulate filter needs a low-ash oil: API CK-4 or ACEA E6, E8 or E9. Older engines and generators without exhaust after-treatment run well on API CI-4 or ACEA E7 grades, which the listings below include.
Viscosity: SAE 15W-40 is the common fleet grade in the Gulf. 10W-40 and 10W-30 synthetic grades save fuel and suit long drain intervals. SAE 40 and 50 monogrades are still specified for some older engines and marine auxiliaries.
The OEM approval: Fleet contracts and warranties often require a named approval such as Mercedes-Benz 228.51, Volvo VDS-4.5, MAN M 3677, Cummins CES 20086 or Caterpillar ECF-3. Tell us the engine and we will quote a grade that carries it.
Drain interval: A full synthetic grade with the right approval allows the extended intervals the engine maker publishes. If the fleet runs on a fixed short interval, a mineral or semi-synthetic grade is the economical choice.
