Question: How does NMF affect a vehicle warranty?
Answer: NMF is safe; it leaves no residue and does not change the characteristics of oil to which it is applied. It does not cause slippage in automatic transmissions or motorcycle wet clutches.
That said, each warranty is unique. The key is to follow your warranty's instructions. In your warranty the manufacturer has probably designated specific maintenance requirements. If you are unclear about something in your warranty, a vehicle dealership can get you answers.
