CANROYAL ULTRA OUTBOARD OIL 4T 25W-40

Canroyal MARINE OIL 30 Series are premium, extra high performance 30 TBN engine oils designed for use in the most severe residual-fueled, medium-speed diesel engines used in marine and stationary power applications. These diesel engine oils have been specially formulated to provide outstanding residual fuel compatibility characteristics to deliver excellent engine cleanliness, especially in crankcase, camshaft areas ring belt and piston under crowns. They provide excellent high temperature oxidation and thermal stability, low volatility, high load-carrying properties and corrosion protection.

Features and Benefits

Canroyal MARINE OIL 30 Series oils have industry
leading thermal and oxidation stability. They have
excellent TBN retention and resistance to viscosity
increases over long operating periods. They also
promote a high level of engine cleanliness with
protection against wear. Compared to other medium
speed engine oils, they have superior lube/fuel
compatibility and separate easily from water.

Applications

Canroyal MARINE OIL 30 Series oils are designed

to meet the needs of engines operating on heavy

fuel. They are recommended for use in the latest

model medium speed diesel engines and are

especially beneficial in engines having low crankcase
oil consumption or operating with low cylinder liner
temperatures. Relatively high alkalinity reserves in
these oils provide superior protection in neutralising
the strong acids resulting from the use of high
sulphur fuels that find access to the crankcase to
promote oil degradation and ring, cylinder, and
bearing corrosion.
