Automotive components use a mix of metals and processes, so no single oil fits all. Cast-iron engine parts suit KG-2B / KG-3B, plated and phosphated fasteners suit KG-2C / KG-3C, sintered powder-metallurgy parts suit KG-4A / KG-4B, and export shipments benefit from long-term grades like KG-8.
Selection table
See the Automotive application page for the full table with typical parts and recommended grades.
Process considerations
Check compatibility with downstream assembly, painting and cleaning, and keep fingerprints off finished surfaces.
Frequently asked questions
Do your oils change the color of cast iron parts?
KG-3B is light yellow and does not yellow during long protection periods; KG-2B is deep brown.
