Oil analysis is a quick, nondestructive way to gauge the health of an engine by looking at what's in the oil.

What does a standard analysis include?
In our standard oil analysis, we perform four tests:

Spectral exam:
In the spectral exam, we take a portion of your oil sample and run it through a machine called a spectrometer. The spectrometer analyzes the oil and tells us the levels of the various metals and additives that are present in the oil. This gives us a gauge of how much your engine is wearing. To learn more about the elements we look at and where they come from in your oil, go to our Report Explanation page.

Insolubles test:
The insolubles test measures the amount of abrasive solids that are present in the oil. The solids are formed by oil oxidation (when the oil breaks down due to the presence of oxygen, accelerated by heat) and blow-by past the rings. This test tells you how good a job the oil filter is doing, and to what extent the oil has oxidized.

Viscosity test:
The viscosity measures the grade, or thickness, of the oil. Whether it's supposed to be a 5W/30, 15W/40, or some other grade, we will know (within a range) what the viscosity should be. If your viscosity falls outside that range, there's probably a reason: the oil could have been overheated or contaminated with fuel, moisture, or coolant.

Flash Point test:
The Flash Point test measures the temperature at which vapors from the oil ignite. For any specific grade of oil, we know what temperature the oil should flash at. If it flashes at or above that level, the oil is not contaminated. If the oil flashes off lower than it should, then it's probably been contaminated with something. Fuel is the most common contaminant in oil.

We can perform our standard oil analysis on any sample of oil, whether it's engine oil, transmission oil, an oil-based additive, power steering fluid, lube oil, hydraulic oil, biodiesel, or another type of oil.

There are more specialized tests we can perform on an oil sample, depending on your needs. For a complete list of the tests we do and their cost, go to our Tests page.

Gas Engine Are 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 New diesel engines cost up to $20,000 each, so it only makes sense to take care of yours. Oil analysis can identify insidious problems that, if left too long, could drastically shorten your engine's life.

If we had to pick the most frequent cause of diesel engine failure, we would choose antifreeze, the killer extraordinaire. There are several ways coolant can get into the oil - head seals, pin holes in wet liners, injector cups...

Motorcycle Oil analysis has long been a common practice among car and truck owners who want to take the best possible care of their vehicles. But lately, an increasing number of people have been analyzing other types of engines too, especially motorcycles.

And why not? If you own a motorcycle, you want to keep it running as long as possible, and oil analysis is a terrific tool for doing so. We have seen samples from most of the motorcycles out there, and chances are good...

Industrial 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 downtime. Quarterly oil analysis can eliminate leakers and other oil-related problems, with the added benefits of saving money in unnecessary oil purchases and the cost of getting rid of waste oil...

Aviation 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. Air-cooled aircraft engines are twitchy, heat-sensitive machines that vary widely in wear...

Marine Sea-going engines require special attention in oil analysis. These engines are not often mechanically different from their land-borne cousins, but they are quite different in their environment and how they are operated. They tend to pull heavy and constant power for long periods of time. The operating environment has the engines 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...

Transmission Transmission and gear oils can be contaminated with metals, solids, and moisture, and those contaminants should be removed before they can damage the system.

Conversely, a test of your ATF, manual transmission fluid, or gear oil may reveal that it's still in great condition, and you don't need to change it as early or as often as you thought...
