Just had a question for you folks. When is it ok to change out the old dino oil and replace it with synthetic? I just changed our oil at about 10,000 miles, second change, and wonder if I should loo...
Before get some PMs asking what the heck and why of these additives...
Once they plate and both metal sliding/touching (there 'should' be an oil film and never allow them to touch...but in the real world, they do touch every once in a while) has co-efficient of friction less than the oil film.
So, 'when' they do touch...no metal on metal, but M-disulfide or T-disulfide so little to no metal worn off
Both are listed as having the lowest co-efficient of friction known to mankind..for now ;)
