Hi guys, new herebut i have a bit of a problem hoping someone could help me with. Ive sent 2 oil sample off on my car and there seems to be a problem.
The engine is the M54 block, and has done ~63000 miles.
Ive owned the car since 46000 miles and it has a FBMWSH.
2 reports here. On the 2nd sample of oil, i had done 1 track day back in June. Engine mods include 3rd cold air feed, and muffler delete. Running Shell V-Power (99 RON Gas), averaging about 26-27mpg. (Ive put the universal avergaes in brackets)

The report from May was as follows:
Iron and lead both read high in the initial sample from your engine. These metals mainly show
bearing wear, though iron can come from any steel part. Both are fairly high for an oil run 7,046 miles, but
not cautionary. Since everything else looks okay, we are not ready to call these results a problem just yet.
The universal averages column shows typical wear from this type of engine after 6,400 miles on the oil. A
little gas was found, but not enough to cause the excess wear. Try 5K miles next. You could also change oil
types, though usually brand doesn't matter.
The latest report from last week:
Oil usage decreased but iron and lead both increased and that is not a good sign. The iron is
coming from steel parts like cylinders, the valve train or rotating shafts. The lead is coming from the
bearings. Both are at cautionary levels indicating excessive wear. Their rate of wear (ppm/mile) also
increased and that shows a mechanical issue inside your engine. No gas, moisture or coolant was found
plus air and oil filtration were normal. All five can be ruled out as factors in this high wear. Track days can
be a factor. Shorten oil runs. This is a Caution report.
I'm concerned about the high iron and lead rates. Is there any way to have the engine checked to see what could be causing the high rate of iron and lead? & hence if its fixable
One thing to note about the latest oil sample is that i didnt change the oil at the time of sampling, cause it was going into the dealership for its service the following week changed by them anyway. So i removed the sump plug and took a quick sample, with no more than 750-1000mls of oil draining from the sump. & would have the oil changed by them anyway
