What happens if some of the iron residue gets into the crankcase because of blowby?
It is expected that some of the catalytic deposit will get into the crankcase. The amount, however, would be too small to cause any harm. An oil analysis will reveal an elevated level of iron which should be expected and considered normal. MAXI-MIZER’s documented results of increased engine life prove that this elevated level of iron SHOULD NOT be interpreted as the evidence of excess engine wear, as would be the normal (and correct) evaluation.
