Are the categories flagged consistent with a rebuild or abnormal wear?
My truck has 30,000 miles on a Fitzgerald glider rebuild with a Detroit series 60. The oil has 15,000 on it and is the third oil in the engine since the rebuild. Aluminum was flagged at 45. Tin was flagged at 7. Potassium was flagged at 121. Magnesium was flagged at 179. The lab suggested checking blow by and re-sampling at half interval. Is this normal for a recent rebuild? Should I change the oil again now and check for blow by or re-sample in 5,000-7,000 miles?
Is this a good question?
