1999 Nissan Navara ute,engine TD 27.
Total kms 160,850
Time on oil 11 months
Fitted with a Motorgard bypass filter and Amsoil SDF 096 full flow.
TP changed every 3,300kms hence need for 5 litres top up oil.

Comments;Please clarify kms are correct.High oil consumption will minimize wear level test results.All wear levels appear normal.Sample at further 5,000 kms.
I rang the lab to ask why no TBN.They do not normally test for TBN and suggested ST,SUL and OXI give a better idea of the oils useful life.Also asked why no Viscosity at 100c.Caterpillar prefer 40c because accuracy is better,ie one cst at 100c makes a big diff and easy to miscalculate.
I have changed the oil and filters and will run for another 20,000kms.The recommended change interval is every 5,000km,oil only and 10,000km for a filter change.This is a pre combustion chamber diesel so I presume it contaminates the oil far quicker than a direct injection motor hence the need for such regular changes.I think I can safely say the Bypass filter has allowed me to extend the oil change interval by 4x.A lot of my trips are short,the temp just gets to the run zone.
What do you think?
