Information sources
We can help you determine the right oil for
your Cat engines, or you can refer to your
Operations & Maintenance Manual or
service publication SEBU6400 (Caterpillar
Natural Gas Engine Lubricant
Recommendations).
Important Terms
Nitration
The formation of nitrogen acids in oil,
resulting in increased viscosity, corrosive
wear, and sludge and varnish on pistons and
cylinder walls.
Sulfated Ash Level
The amount of non-combustible material
(ash) left when a certain quantity of oil is
burned using a standard industry test
method. These compounds contribute to TBN
or oil alkalinity.
Oxidation
The combination of oil and oxygen that
degrades oil, resulting in increased viscosity,
as well as varnish and sludge deposits.
Cat Oil Filters for the Best Protection
Oil change intervals for spark-ignited gaseous fueled engines are several times
longer than with diesel engines. The increased demand on the oil filter makes it
very important to use the best quality filters in conjunction with the best natural
gas engine oil. Cat filters are the best available, featuring spiral roving, acrylic
beading, a non-metallic center tube and molded polyurethane end caps.
S·O·S SM Services for Early Detection
We recommend protecting your investment by using S·O·S Services. Our S·O·S
Services program is the ultimate detection and diagnostic tool for your equipment,
helping you to detect potential problems before they can lead to major failures and
costly unscheduled downtime.
Health and Safety
