Biolube 100 has been specially developed to meet increasing
environment demands of biodegradability, low hydrocarbon emissions
and low toxicity.

Product Application

Castrol Biolube 100 is our prime recommendation for outboard and jet
ski engines used in competition. Petrol/oil ratios are much lower in
racing than for unmodified engines used for normal boating. Castrol
Biolube 100 has been successfully used around the world in
competition engines. The appropriate petrol/oil ratio will depend on the
degree of engine modification and maximum engine speed. Higher
petrol/oil ratios can be used for lower engine speeds.

NOTE 1: Modified engines in outboard and jet skis should use
petrol/oil ratios as per competition applications whether
involved in competition or not.

NOTE 2: Many manufacturers have revised their lubricant
recommendations for two stroke outboard engines to
NMMA TC-W3(TM) for 1992/93 models onwards, Castrol
Biolube 100 is a qualified TC-W3(TM) lubricant Licence
Number 3-51020. Castrol Biolube 100 may be used
where either TC-W3(TM), TC-WII(R) or TC-W lubricants
are specified.
