Super High Performance Diesel Engine Oil
- High-speed diesel engines operating on distillate fuels.
- N.B. Not suitable for N. American automotive type engines, for which API CF-4 type oils are required.
Outstanding piston cleanliness
Free-running piston rings, even under difficult operational conditions, ensuring maximum reliability.
Exceptional protection against bore polishing
Control of blow-by and oil consumption, preserving engine efficiency. SHPDO type oils are preferred by many engine manufacturers to guard against bore polishing.
Exceptional engine cleanliness
Ability to retain high levels of soot safely in suspension, even with extended drain intervals.
Oxidation resistance twice that of conventional oils
Ability to withstand high temperatures for longer, in severe service or with extended drain intervals.
High reserve alkalinity
A TBN-E (total base number) of 17 to neutralise acids and provide corrosion protection until the next drain interval, even with the higher sulphur levels sometimes found in marine distillate fuels.
