What causes low magnesium levels on an oil sample?
About a month ago I started to notice that my oil was looking kind of sludgy and had an unusual smell to it. I have also been experiencing some inconstant fuel mileage so I decided to have the oil pulled after appx 6,000 miles and sampled the oil.
I just looked at the sample results today and they have flagged my magnesium levels. The level is at 547 vs 784, 813, 721 during previous samples. I have only had the truck since July.
Since I've changed the oil 12000 miles ago I have not noticed the sludgy appearance. Was it possible I just got bad oil?
Is this a good question?
