I have a 92 American Eagle with a 8.3 engine with 77,000 miles which has just started to leak from the rear of the oil pan , I'm ready for an oil change and have seen an additive that suppose...
Does the product have the word 'Miracle' in it's name?
I wouldn't risk substituting or diluting the oil. In particular is the concern for the turbo bearings which are cooled and lubricated with the same oil. Better off just getting it fixed.
