Shell's Caprinus R Oil guards towboat EMD's against corrosive wear of rings and liners.
The switch is on!
Here's why over 40 towboats are now
using Shell's high-alkalinity Caprinus R Oil 40.
We were proud to introduce Cap-
rinus® T Oil a few years ago and
delighted with its performance on
the waterways. Caprinus T is a
hard act to follow. But Caprinus *
R Oil 40 is a significant step
ahead. Towboat operators agree
and are now using this premium
lubricant in over 40 EMD-
powered motor vessels.
Caprinus R Oil 40 is higher in
initial alkalinity than Caprinus * T
Oil (10.2 TBN-E compared to
7.5) and retains effective alkalin-
ity in extended high-stress ser-
vice.
That means Caprinus R Oil can
continue to neutralize combus-
tion acids and guard against cor-
rosive wear of rings and liners
over long periods. It helps pre-
vent corrosive wear caused by
high-sulfur fuels.
Maximum filter service life
The dispersant additive system in
Caprinus R Oil helps keep insolu-
bles in suspension to promote
engine cleanliness. Results: In
some installations it has been
possible to extend filter service
life to the limit of filter element
durability—an important main-
tenance saving.
And what engineer wouldn't
like the long oil service life of
Caprinus R Oil! It offers high oxi-
dation stability, high detergency
to meet the needs of the latest-
design diesels with up to 250 hp
per cylinder. Fights thickening
and deterioration over the long
haul, too.
Caprinus R Oil has all the
properties to do the job and keep
at it!
Workhorse Tornus® Oil will
still be available
For many years, Shell's Tornus*
Oil has worked its way in and ac-
ross ports, harbors and the inland
waterways of the U.S., deliver-
ing good performance in high-
horsepower diesels. Its alkalinity
level is considerably lower than
that of Caprinus R Oil (TBN 5.7
compared to 10.2). But it does
provide good wear protection,
helps keep engines clean and
gives good oil and oil filter life in
moderate service.

Shell will continue to offer Tor-
nus Oil but encourages a change
to Caprinus R Oil 40 to meet the
demanding requirements of mod-
ern engines and high-sulfur fuels.
