Hello! This is my first oil analysis, it has a high soot level. My question is this... Is it possible that the high soot could have been from the vehicle sitting for a few days while it was serviced? I don't think the mechanic ran it to circulate the oil and warm up the motor (would the soot settle?). He used the drain to get the sample instead of a pump. Also, could the use of Amsoil be cleaning out the motor and contributing to the soot? I want to be able to go with extended intervals. I may have to add a bypass filter if soot levels stay the same after oil change.
This sample is from a 2000 Volvo VNL64T w/Cummins N14. Miles on oil at time were 24532, with 508485 on the tractor total. Oil is Amsoil's Series 2000 Heavy Duty Diesel 5w30. Filter is a Donaldson Extended Life (ELF) 7300. I bought the truck at 466k miles, and this was the first Amsoil to my knowledge. It was in a fleet before I bought it, so I am assuming Rotella or other standard fleet type oil was used prior.
Here it is:
iron....45
chromium...13
lead...10
copper...33
tin...0
aluminum...3
nickel...0
silver...0
silicon...6
boron...2
sodium...0
magnesium...55
calcium...3602
barium...0
phosphorus...1171
zinc...1346
molybendum...9
titanium...0
vanadium...0
potassium...0

soot/solids...5.3
coolant...no
tbn...6.40

nitr...n/a
Looking forward to your expert opinions!
