Engine Life Increases 500%

More than 60,000 tourists annually visit Alpine Canyons, South Island, New Zealand
for high-speed thrills on Shotover Jet Ltd. jetboats.

The tourist trade is tough service for the boats. The Chevrolet 454 cu. in. V8-engined
jetboats are in service 365 days a year, making up to 28 high-speed river trips a day.
The boats develop maximum torque at extremely low engine operating temperatures,
due to the cooling effect of the snow-fed river water they draw. How does Shotover
protect these hard-working engines?

With AMSOIL synthetic motor oils and AMSOIL by-pass oil filters. Before converting
the boats to AMSOIL motor oil and filters and propane fuel, oil change intervals
were at 25 hours and engine life in the 500-hour range. The propane fuel, AMSOIL
synthetic motor oil and AMSOIL by-pass oil filter combination provides 400-hour
oil change intervals and engine life up to 2500 hours — that’s 16 times greater oil
service life and five times greater engine life — a huge savings for Shotover Jet Ltd.
