About diesel engine lubrication

Diesel engines require the correct lubrication to keep it running at optimum performance.

Engine oil provides three key functions in a modern internal combustion engine. First of all, it helps keep engine components working smoothly together. Secondly, the inside of an engine, a place where there are thousands of controlled detonations happening every minute, can be a hot place, and oil helps draw heat away from the combustion chamber. Lastly, it helps prevent carbon and varnishes from accumulating in the engine.

There are many types of engine oil, but it’s vital you check your service manual which should tell you the appropriate viscosity of oil — like 15W/40 or 5W-30, for instance — that your engine requires.

Some run on purely a mineral based oil and more modern engines require semi or fully synthetic to help meet the engine manufacturers recommendations.
Viscosity is the measure of how much resistance a fluid has to flowing. Many would refer to it as the “thickness” of a fluid; honey has more viscosity than water, for example.  There’s more to oil, though, than just viscosity. The American Petroleum Institute certifies oil based on performance criteria determined by automakers, engine builders and oil producers. Oils that meet the standards receive the API Certification Mark, which should be easy to see on an oil container.

What if I don’t change my oil?

One of the problems is that there will begin to be build up in the cooler parts of the engine, like the crankcase and around the camshafts and valves. This can lead to carbon deposits, or sludge, coming out of the old oil. That could require an expensive engine cleaning or force you to replace worn-out piston rings. It can get worse. The pistons could eventually seize or the camshafts could be damaged. Getting a bill for either one of these repairs would make even a few high-quality oil changes look like pocket change. Consider regular oil changes to be like really cheap insurance for your engine.

Oil analysis is a way to determine the condition of the inside of your engine. The laboratory report can indicate excessive wear from metal particles from the engine within the sample that could help you to forward plan maintenance before an engine failure occurs.

It may only indicate that the oil is due for change but this service offers piece of mind.
