After much searching, we finally found a boat owner who's not using

CAPRINUS® Oil.

And that wasn't easy. Because the fact is, you can find CAPRINUS U Oil just about anywhere you find hard- working inland marine boats.

CAPRINUS is Shell's top-of-the-line, premium- quality marine oil specially formulated for extended service in medium-speed diesel engines.

Our single grade, CAPRINUS U Oil 40, is a high- dispersant, zinc-free* oil which provides excellent protection and keeps engines running clean.

CAPRINUS U 20W-40 Multigrade lowers operating costs by reducing oil and fuel consumption versus single grade oils. It also delivers excellent engine protection, which reduces maintenance costs in the long run.

We're so confident of the quality of CAPRINUS Oil, we back it with a written warranty. If it does not perform as promised, we'll pay to repair any engine damage caused by oil failure. Some restrictions apply.

For further details or a copy of the warranty, contact your local Shell jobber or call 1-800-231-6950. *Zinc level less than 10 ppm
