Delo Gold Ultra T SAE 10W-40: Is synthetic blend, a myth or a reality?
In the fleet industry, an uninterrupted movement of trucks is key. Maintenance of the diesel engine performance for extended drain is essential. Keeping the engine clean and protecting it from wear and tear are the most important functions of the engine oils. Delo Gold Ultra T SAE 10W-40 has proven that its highly effective detergent additive system minimizes piston crown land deposits which can lead to harmful bore polishing, and its metallo-organic anti-wear additive system lessens wear in severe service by creating a protective layer on all metal contact surfaces maximizing engine life.
Its exceptional high-temperature stability minimizes degradation that leads to sludge formation and oil thickening and provides extended oil drain capability while providing efficient dispersion of soot particles, offering filter plugging protection. Its highly shear-stable viscosity index improvers prevent oil flow through the piston rings by maintaining oil viscosity in the high-temperature ring belt area, while special low volatility base fluids minimize evaporative oil loss.
The question raised about Delo Gold Ultra T SAE 10W-40’s synthetic blend and its effectiveness can be well-established through an example of Mitsubishi Fuso engine that clocked over 630,000 kilometers while running on Delo XLD Multi-grade SAE 10 mm 40 and achieving oil drain intervals of over 40,000 kilometers. What was observed was that this engine has been using diesel with a fuel sulphur level of over 500 parts per million, which is 30 times higher than that which is found in many other countries. On this piston, on further examination of the engine’s top, minimal deposits were found. While when we look at the sides, we also see minimum deposits, which show that Delo XLE multi-grade has adequate detergency and keeps the piston clean for a long time. However, it has been observed that when we also look at the piston rings, it can be seen that they are all moving freely with no sticking. Then, when we turn over the piston and look under, it is observed that it's all clean with no underground deposits—proof that Delo acts on mulch grid even at over 40,000-kilometer oil drain intervals and still keeping the engine running.
It is critical that all the oil rings are moving freely while the engine is operating. What this means is that the rings maintain a good seal between the combustion chamber and the crankshaft, due to which that power is transmitted to the engine, ensuring the truck’s capability to carry a heavy load. It was also observed that all the pistons were in great condition even after 630,000 kilometers and 40,000-kilometer oil drain intervals.
An examination of the vehicle’s oil filter and the sample about what was important about the oil is that it should flow, and there should be no sludge. In each of these case studies, Inspection of the bearing showed that all the bearings were in good shape, with no sign of copper and a clear metal overlay. In the end what was confirmed was that along with best practices of maintenance and with the usage of Delo Gold Ultra T, excellent protection to the engine can be realized.
