Hello:
Blackstone reports too much iron and a little too much aluminum in my last two samples.
There were 43,750 miles on the car at the time of the most recent sample The most recent is 6,250 miles on Mobil 1 5-20. The previous sample was 7,500 miles on Pennzoil Platinum 5-20. The first two samples apparently showed no excess iron in runs of slightly less than 5,000 miles. The very first sample was with Car Quest 5-20 oil and the second was with Motorcraft 5-20 synthetic blend. I drive many short trips to the public transit station (1.5 miles each way) three or four times a week. I barely average 9,000 miles a year. I use OEM Kia oil and air filters.
On the plus side, my engine uses virtually no oil between changes. I've never had to add oil and I check it at the same gas station every two weeks.
Any ideas of why I'm getting so much iron and what should I do about it?
