Marine Engine Oil Lab Analysis
Spot possible issues with your marine engine prior to problems arising by having
your oil studied! Oil examination is the easiest, simplest and cheapest solution to constantly keep watch over the shape of your vessel's transmissions, generators and engines. As part of a yearly maintenance plan, getting an oil analysis allows you to recognize possible problems prior to the machinery really quitting.
Lubricating oil reduces friction and damage among moving components, aids in reducing the temperature of the engine and removes foreign matter at oil changes. The friction of these components makes microscopic metallic shavings, an accumulation of dirt, grunge and sulfur from when combustion takes place.
Facts of Oil Analysis
The assumption behind performing an oil analysis is that, as mechanical equipment is run, the metallic parts of the machinery are subject to friction and tiny particles will hang about in suspension in the oil. This can be measured for both size and kind by the laboratory. An oil analysis will identify higher than standard readings to provide you with a "heads up" on looming problems. You can get an oil analysis performed by any of the foremost engine producers at a dealer for Volvo, Cummins and Caterpillar; additionally , there are a few superior independent labs in existence. Oil analysis is a useful tool as a part of any marine survey, and I suggest that transmissions, engines and generators be evaluated as part of all pre-purchase surveys. Although oil analysis is designed as a part of a continuing maintenance program, a single test can inform you and your surveyor quite a lot regarding the soundness of an engine. The analysis results are determined by the hours of your engine and the hours relating to the oil.
Analysis Results
The analysis results will be a sign of whether or not the equipment is working as intended. If the oil is found with no extremely high readings, this analysis will function as a base line for forthcoming testing. At Paradise Yachts we recommend conducting an oil analysis yearly as an aspect of your preventative maintenance program. If oil testing is performed in using this method, any deficiency is going to be discovered timely and this will save you thousands in repair costs.
Performance of an oil testing program with annual testing will, in reality, raise the value of the yacht. Given that equipment is pricey and if it can be shown that oil laboratory analysis was completed and deficiencies were fixed upon discovery, a possible boat buyer will look favorably upon those results. A clean report will prove that the engines are healthy.
Oil Sample Interpretations
A good laboratory will provide an easy to read and comprehend report on the findings. The lab will decipher the results for you as Severe, Abnormal or Non Detected. Recommended corrections will frequently be given also.
ALUMINUM
High numbers prove irregular wear on bearings, bushings, turbo chargers or pistons
BORON
Illustrates wear with water, coolant leaks, dust, seals, coolant additive.
CHROMIUM
Elevated values show irregular deterioration on shafts, rings.
COPPER
Detected on bushings, oil coolers, bearings
GLYCOL
Indicates a coolant problem, probably leakage from fresh water cooling system
IRON
Reveals abnormal friction on blocks, gears, rings, cylinder walls and heads
LEAD
Overlay on main and rod bearings
MOLYBDENUM
Extreme wear with piston ring metals
MANGANESE
Deterioration with valves, blowers and exhaust leaks.
OXIDATION
This results from a chemical response with oxygen and oil that causes oil to congeal and lose its lubricating components. Brought about largely by high temperature operation and/or over due oil changes.
POTASSIUM
Excessive readings indicate a coolant contamination predicament.
SILICON
Illustrates the existence of contagion by dirt or gasket material.
SODIUM
Shows likely seawater intrusion.
TIN
Indicates wear on bushings, bearings and pistons.
WATER
Shows a coolant issue or might be condensate. Positive analysis suggests the presence of a minimum of 0.5% contamination. This may result in lower oil lubrication ability and an increase in rust formation
SOOT
Elevated soot readings means flawed air combination, residue of partially burned fuel that can thicken oil, exhaust oil additives and sooner or later plug filters. Found solely in engine samples.
