Blackstone Comments:
Thanks for the note about switching back to the OEM air filter. The K&N filter was working well, as
seen by the low silicon readings, but there's nothing wrong with going back to the factory spec. Wear metals
were fairly steady compared to the last sample, so your engine didn't mind the extra miles on the oil. In fact,
we wouldn't be surprised if things held this steady after a longer oil run. Maybe even after a 5,000 mile
interval. Iron might increase (normal), but all else should stay around average. The TBN was good at 2.9, so
try 5,000 miles next. Nice job!
What is interesting is that I was reading/posting in the air filers section. People here really don't seem to like K&N and I saw some UOA's where they were not fitlering well at all....so I decided to get an OEM Hyundai filter and switched it back in after I took the sample. However, according to this sample, my K&N seemed to be doing just fine....Si was decently low....What do you all think??
Also I am a little concerned about the lead increase. Bearings? or is 1 ppm nothing to worry about?
thanks!
