Hi,
this is the latest Used Oil Analysis result from my Porsche Boxster (986) 2.7ltr Tiptronic
Engine data
M9622 & Tiptronic @ 111650 kms (69335miles)
Operation over 14598kms (9065 miles) - 14+ months
A number of long high speed trips (80%) and a small amount (20%) of Urban running. Revs rarely above 6500
While I was in Europe the car stood idle for about 9 weeks
No top up lubricant was added
Location
Australian Tropics - high humidity (up to 98%)
Lubricant
Mobil's Delvac 1 5w-40 (CI-4/SL)
(Previous Report results shown in brackets)
Lubricant condition
Water = 0.00 (NA)
Fuel = 0.00 (NA)
Viscosity @ 40C = 87 (88) cSt
TBN = NA (6.4)
TAN = 3.3 (NA)
Soot Index = 0.1 (NA)
PQ Index =
Elemental analysis
Iron = 3 (12)
Aluminium = Chromium = Copper = Lead = Potassium = 2 (6)
Silicon = 8 (18 due to gasket sealant)
Sodium = 1 (5)
Tin = Oil consumption = nil
Summary
Whilst the lubricant was obviously still suitable for continued use I changed it and the filter due to an impending long (3500kms/2173miles) high speed journey (now over)
