Lab Reports Require Quick Action
Unless you have special arrangements, most laboratories retain your
oil sample for only a short period of time. Seven to 14 days is typical.
When you get back your reports and have a questionable result or want
to have additional testing performed, call the lab immediately to avoid
the risk of your sample being discarded.
Reasons for Increased Viscosity
Assuming that no water is emulsified in the system, some reasons
for an increase in viscosity of a circulating oil might include: the oil
may have oxidized, pressure could have increased, temperature might
have decreased, possible contamination with a higher viscosity fluid,
evaporative losses of light oil fractions from high temperatures, glycol
contamination and soot contamination.

Inspect Your Oil Level Gauges
Routinely inspect the vent hole in column-type vented level gauges. In dirty environments, the vent hole
can become easily plugged, causing an air lock in the gauge headspace. is will result in a false oil level
(higher than reality) in the gauge. Many prefer dual-port gauges instead (unvented).

Getting More from Your Reservoir
A properly constructed reservoir is more than just
a tank to hold the oil until the pump demands fluid.
Whenever practical, it should also be capable of dissi-
pating heat from the oil, separating air from the oil
and settling out contamination in the oil. Never mix
lubricants.
