Hello everyone.
This is my first analysis on this engine.
Oil..........Mobil Delvac 1
km (total)...121 000km (45 000k on Delvac 1)
oil...........11 000km
oil filter.....1 000km (Donaldson)
oil added......1.5-2 litres
air cleaner....K & N (standard housing)
Analysis
- Metals (ppm)
Al.............7
Cu.............3
Cr.............1
Fe............19
Pb.............5
Sn.............1
-Contaminants (ppm)
Si.............6
Na...less than.1
-Physical Tests
TBN............13.7
Water.less than 0.1%
Vi @ 100*C.....15.2 cSt
Soot............0.6%
PQ index.less than 20 (total iron in sample irrespective of size)
Fuel............1%
So what does everyone think ?
How far will this oil go ?
What about the iron figure ?
Are silicon figures an accurate indicator of air cleaner efficiency ?
These tests were performed by Australian Laboratory Services, Brisbane, Australia.
thanks in advance,
Rick.
