A. E. "Bud" Dacus finds Caprinus R Oil W helps keep EMD-567Cs in top condition. "Works equally well in my Detroit Diesel 6-71 auxiliary dieselshe says.
"I'm impressed-Shell's Caprinus® R Oil 40 keeps my EMD's in
better condition than any other oil I've used in 20 years."
Says A. E. "Bud" Dacus,
Chief Engineer of the
M/V Crescent City since
her launching in 1958.
"We've tried a good many engine oils
in the Crescent City over the past 20
years," continues Mr. Dacus, veteran
engineer for the Sioux City-New
Orleans Barge Company of Hartford,
Illinois.
Absence of carbon or ash deposits on piston
undercrowns demonstrates outstanding
stability of Caprinus T and Caprinus R Oils.
"Until recently we considered
Shell's Caprinus*T Oil 40 the best.
It kept our EMD's in fine condition.
But Caprinus R Oil 40 looks even
better."
Mr. Dacus made his comments dur-
ing a routine teardown of his EMD
16-567Cs after 18,875 hours of ser-
vice. The engine photographed had
been on Shell's Caprinus T Oil and
switched to Caprinus R Oil for the
last 5,000 hours.
Exceptional Cleanliness
"I never saw an engine look so clean
after 5,000 hours on any oil," adds
Mr. Dacus. "It looked even cleaner at
18,875 hours than at the 13,000 hour
mark. Top decks had just a light oil
film. Intake ports were wide open.
Practically no sludge in the sump.
Minimum wear on rings."
Guards against corrosion
Caprinus R Oil 40 is higher in initial
alkalinity than Caprinus T Oil (10.2
TNB-E compared to 7.5) and retains
effective alkalinity in extended high-
stress service. It neutralizes combus-
tion acids and guards against corro-
sive wear of rings and liners over long
periods.
Filters frequently last longer, too.
Caprinus R Oil's dispersant additive
system helps keep insolubles in sus-
pension, prevent heavy deposit
buildup. Result — the possibility of
significantly extended filter service
life, an important maintenance saving.
The switch is on to Caprinus R
Top engine performance is why nearly
100 towboats, including ten from the
Sioux City-New Orleans Barge Com-
pany, have already switched to Shell's
Caprinus R Oil. Look into this high
alkalinity engine oil for your vessels.
It could mean important savings in
operating costs for you!
Intake ports for an EMD 16-567C cylinder
are completely free of deposits after more
than 13,000 hours on Caprinus T Oil and
5,000 hours on Caprinus R.
