Recently, we received an enquiry from one of our existing customer regarding one of our products, Gazpromneft Diesel Premium 15W-40 CI-4. Since we already have proven records of how well the oil performs in light trucks (see HERE and HERE), the like-minded curious customer wonder how will the oil performs when it is used in heavy duty diesel engine especially in their heavy loaded trucks, driven over long distance daily under the hot and humid Borneo weather, harsh and hilly road condition.

It struck our curiosity hence we collaborated with our customer to carry out an UOA (used oil analysis) on one of their prime mover, which is a UD Nissan Diesel CW 6X4 with GE13-TD (13,074cc, straight 6, turbocharged & intercooled) engine. The prime mover has been running on the Gazpromneft Diesel Premium 15W-40 CI-4 for about 15,000 KM before oil sample is taken for UOA.

What is oil analysis? Oil analysis is a routine activity for analysing oil health, oil contamination and machine wear. The purpose of an oil analysis program is to verify that a lubricated machine is operating according to expectations. When an abnormal condition or parameter is identified through oil analysis, immediate actions can be taken to correct the root cause or to mitigate a developing failure.

Why perform oil analysis? An obvious reason to perform oil analysis is to understand the condition of the oil, but it is also intended to help bring to light the condition of the machine from which the oil sample was taken. There are three main categories of oil analysis: fluid properties, contamination and wear debris.

The UOA shows very promising results even after 15,000 KM. The amount of wear metals is minimal indicating that the oil is doing its job protecting the engine. The amount of additive is still very high, only depleted 3.1% for Calcium (detergent), 8.5% for Phosphorus and 5% for Zinc (both anti-wear). The viscosity dropped but stay within the SAE 40 grade. The TBN has dropped 2.11, equivalent to about 35% of usable oil life. The UOA results indicates no abnormal findings and the oil is still good to go for at least another 5,000 KM.

Gazpromneft Diesel Premium is a good option if you wish to protect your machineries’ engine while extending your drain interval, its proven oil quality also helps to reduce maintenance and repair cost over the long run. Contact us for more information or request for quotation.
