Why get fluid analysis?
Oil travels through many moving parts of an engine while it is operating picking up trace elements plus contaminants such as water, anti-freeze, particles, etc.. Knowing what and how many elements or particles are mixed with the oil can give us clues of wear and impending catastrophic failure. Even a hairline crack on a cylinder can be picked up from analysis of oil!
This is somewhat analogous to going to your doctor for a physical. He draws a blood sample because blood is pumped through every organ in your body picking up chemicals, enzymes, etc.. The results of a blood test screening can tell the doctor the condition of many organs in your body. THERE IS NO SUCH THING AS A PHYSICAL WITHOUT BLOOD ANALYSIS!
Same with fluid analysis. A Marine Survey without fluid analysis is an incomplete examination of a machinery. We strongly recommend fluid analysis on every survey.
WEIGHING THE $60 COST OF OIL ANALYSIS AGAINST WHAT IT COULD TELL YOU MAKES IT A BARGAIN!
Clients sometimes tell me to just look at oil first and see if it looks contaminated before taking sample. Reality indicates that you need oil analysis when the oil looks clean because that's when you can't see TRACES of contamination. If you see it, then you know it's there and you don't need an oil analysis! Other clients have said that maybe the oil was just changed and problems would not be picked up. This may be true for element traces of wear but more serious matters like cracked heads or blocks spill water and antifreeze into the oil and there's usually enough to show up after only a few minutes of operation.
FLUID ANALYSIS WILL TELL YOU MORE THAN COMPRESSION CHECK AND COMPUTER DIAGNOSTICS COMBINED FOR A FRACTION OF THE COST!
Marinetech can have results of engine fluid analysis included with your Survey Report 48 hours after the inspection since we personally deliver to lab at end of inspection the same day.
