The name, L.P.
& NATURAL GAS ENGINE OIL, explains its use. It is a low ash
oil designed for stationary l.p. and natural gas engines. It is an amber
colored, high viscosity index oil. This means minimum thinning out under
heat or thickening up under cool temperatures. A high viscosity index oil
will thin out less under heat than an oil with a low viscosity index.

L.P.
& NATURAL GAS ENGINE OIL
Controls
Deposits
Several years ago, natural gas engines
were commonly lubricated with uncompounded naphthenic oils or conventional
motor oils. Unfortunately, with those lubricants, oil deterioration and
engine deposits resulted in frequent shutdowns for maintenance. Texas Refinery
Corp. has formulated an oil with additives chosen specifically for l.p.
and natural gas engine service. A low ash additive package is used which
significantly improves piston deposit control.
L.P.
& NATURAL GAS ENGINE OIL
Is
A Low Ash Oil
Texas Refinery Corp.'s L.P.
& NATURAL GAS ENGINE OILS are considered low ash products. They
have a sulfated ash value much less than the top limit to be considered
a low ash oil. The sulfated ash weight percent is .50. This low ash formula
certainly helps to reduce excessive piston top land deposits. High ash
oils used in an l.p. and natural gas engine
when the fuel has a concentration of
hydrogen sulfide (H2S) at 0.10% by volume or less can create
deposit buildup which can lead to valve, combustion chamber and turbo damage
over longer operating type. High ash oils in these types of engines can
create deposits resulting in shorter engine life.
L.P.
& NATURAL GAS ENGINE OIL
Contains
Quality Base Oil
The refining processes Texas Refinery Corp.
uses for its base oils make L.P. & NATURAL GAS
ENGINE OIL one with outstanding quality characteristics. The base
oils go through a solvent extraction process that removes undesirable characteristics
that might lead to sludge and gum under heated conditions. The oils then
go through a hydro-treating step which improves its oxidation resistance
as well as its response to the superior quality additives used by Texas
Refinery Corp. Last, but not least, the oils go through a dewaxing process
making them highly desirable products for lower temperature application.
These special refining steps make the oil much better than is called for
by specifications of an l.p. & natural gas engine and it is an exceptional
quality product that can be used in other applications.
L.P.
& NATURAL GAS ENGINE OIL
Does
Not Contain VI Improvers
Texas Refinery Corp. L.P.
& NATURAL GAS ENGINE OILS do not contain viscosity index improvers.
Some engines equipped with electrical governor actuators are not compatible
with viscosity index improver polymers. This is because the crankcase oil
lubricates these controls and precise control of those engines using electrical
governor actuators cannot be provided if the engine oil uses VI improver
polymers.
L.P.
& NATURAL GAS ENGINE OIL
Helps
Spark Ignited EnginesTexas Refinery
Corp. L.P. & NATURAL GAS ENGINE OILS provide
excellent service in heavy-duty spark ignited engines. Using these oils
in the 7,000 hour field tests indicated no ring sticking or ring scuffing.
In addition there was no liner scuffing or carbon cutting from excessive
piston top land deposits. Oil consumption did not exceed the test requirements.
Valve recession also did not exceed the limits. At the end of all specified
oil change periods, the oil condition remained within limits for oxidation,
nitration and Total Base Number (TBN).
L.P.
& NATURAL GAS ENGINE OIL
Has
Excellent TBN
Texas Refinery Corp. L.P.
& NATURAL GAS ENGINE OIL has a TBN of 7.0. This is low in comparison
to some of our oils used in other engines; however, most low ash oils used
for l.p. and natural gas engine service only have Total Base Numbers of
5. The extra measure of safety with Texas Refinery Corp. L.P.
& NATURAL GAS ENGINE OIL means it is possible for these oils
to neutralize more acids and protect against the harmful effects of acids
better than many of the commercial oils on the market.
Typical applications for L.P.
& NATURAL GAS ENGINE OIL include engines manufactured by Caterpillar,
Clark, Cooper-Bessmer, Cummins, Fairbanks Morse, Ingersoll-Rand, (category
I, II and III), Stewart, Stevenson, Superior & Waukesha V.H.P. which
call for low-ash-type oils for l.p. and natural gas engines. |
