Would it not be more beneficial to have the oil tested on e36 or older car (thus simulating what an e46 analysis will predict a couple years down the road)
I ask because I would not expect much deterioration to be found in a brand new engine....it's after a couple years when seams stretch and things get loose that one can determine if frequent oil changes are truly required.............Great post though


I had my oil analized last week and just got the results back.

: 1999 E46 328i 28,000 miles on the odometer
: 11,000 miles since last oil change with BMW synthetic 5W40
: (approx 50/50 highway/city)

: The reports states that the oil still falls within the spec'ed viscosity range (5W40)
: no trace of fuel, water, or antifreeze in oil.

: and traces of metals (aluminum, iron, copper and about 4 other types of metal) were all virtually non-existant.

: traces of silica (dirt) are also very minimal. (using K&N air filter) (there was a side note that said air filter is
: working properly)

: The conclusion of the report was that the oil is suitable for continued use and engine is in excellent condition.

: I think BMW engineers know what they're doing, and it'll be safe to go 15k to 18k before changing the oil.

: When it hits 18k, I'll send the oil in to be analized again and will post the results.
