Hi,
this is the UOA from my M291 engined (4 cyl, supercharged) CLK Benz
The following "Life To Date" operating data is relevant and straight off the vehicle's computer
Distance (LTD) - 48000 kms (29800 miles)
Average speed (LTD) - 60 (61) km/h (37 (38) mph)
Fuel used (LTD) - 7.9 (7.8) litres per 100km
Use (LTD) - Approx 80% Hiway/20% Urban
DATA FOR THIS UOA
Lubricant - M1 0W-40 (SM/CF)
Filter - OEM
OCI distance - 15889 kms (9867 miles)
OCI time - 24 months
Oil topup - Zero
Mercedes Benz ASSYST data;
OC due at two years (time limit overwhelms distance)
OC done 14 Jan 2011 - two days under time limit of two years
OIL ANALYSIS - (Last OCI in brackets)
Viscosity @ 40C - 78 (82) cSt
Nitration Abs/cm - 24 (27)
Water %v - 0 (0)
TBN mgKOH/g - NA (3.6)
TAN mgKOH/g - 3.7
ELEMENTAL ANALYSIS
PQ Index -
All in ppm:
Iron - 49 (59)
Aluminium - 4 (6)
Chromium - Copper - 17 (19)
Lead - 3 (8)
Potasium - 3 (5)
Silicon - 9 (11)
Sodium - 7 (11)
The lubricant was judged as being suitable for continued use however
the oil was changed out and replaced again with M1 0W-40 (SM/CF)
NOTE
This period included 2 x 2 months when the vehicle was not used whilst I was in Europe
Sadly this is the last UOA for me from Mobil's Lab in Yarraville, Victoria, Australia as this facility is being decommisioned at the end of February 2011. I have used this facility for many many years!
All future Oil Analysis will be done via ExxonMobil's Signum Labs in the US. This follows ExxonMobil's stategy of becoming a Wholesaler in Australia
All of its Petrol Stations have recently been sold off to 7-Eleven as part of this programme
