Engine Types

Gas Engine

Gasoline EnginesAre you changing your oil often enough? Too often? Is that synthetic oil really worth it? A decade ago, the commercial multi-weight oils on the market were similar. We didn’t see much difference in the various brands, and the only real choice for consumers was the grade. Then synthetics were introduced, as were many types of oil additives. Suddenly the question of what to put into your engine became more complicated.

Diesel Engine

Diesel Engines

Diesel engines can last hundreds of thousands (if not millions) of miles, but will yours last that long? Without oil analysis, it can be hard to know what’s going on inside the block. An analysis can identify insidious problems that, if left too long, could drastically shorten your engine’s life. Maybe your engine is struggling with fuel dilution due to a leaky injector or a bad pump. Or maybe antifreeze…


MotorcycleMotorcycle engines tend to lead a much different life than the average car or truck. They often see hard use during the summer, and when the weather gets cold, many of them are stored for the winter. Is the hard, seasonal use too much for your engine? ? Is your air-cooled V-Twin running hot and causing the oil to oxidize and thicken…


IndustrialMaintaining a line is hard work. Industrial groups have traditionally changed oil on an elapsed-time basis. This can result in dumping millions of gallons of good oil annually, while doing little to prevent oil-related problems such as “leakers” — machines that leak oil from various seals, costing millions in new oil purchases and waste oil disposal. Instead of changing the oil based on time or visual appearance, let oil analysis provide you with the hard data you need to keep your machinery in good…


Aircraft Engine

When a gasoline or diesel engine develops an unexpected problem, it leaves the owner stranded at the side of the road. When an aircraft engine develops an unexpected problem, it can have far more serious consequences.

Oil analysis is a critical component of aircraft maintenance. It’s just one tool in your bag of tricks to keep your engine running in top shape.



Sea-going engines are similar to their land-borne cousins, but they are quite different in their environment and how they are operated. Engines are often situated in holds with little air for cooling and little room for maintenance. Some are treated to splashing bilge water and use seawater for cooling. These are all factors to consider when analyzing the oil.

Does sitting over the winter cause corrosion? Are you…



Automatic transmissions ask a lot of the oil. Not only does the oil lubricate and clean internal parts, but it also functions as a hydraulic oil to operate various components.

Transmission oil can be contaminated with metals, solids, and moisture, and those contaminants need to be removed before they cause problems. Conversely, a test of your transmission fluid may reveal…
