My friend told me that some Toyota dealer is offering engine oil additive that can last 50-80k km, not sure the exact name but sounds very similar to Militec (not PTFE-based/Moly based)
Most of the people opt the package, they find the car more responsive, sounds moother and some has improved fuel mileage.
I am wondering what is the adverse effect of this additive and what brand that is never been proven causing damage to engine ?
Thank you
