Terpel HD 25W-60 API CF-4

Terpel HD 25W-60 API CF-4 high-viscosity mineral oil is specially formulated for the protection and lubrication of heavy-duty diesel engines with high mileage or high wear, operating under demanding work and temperature conditions.

Terpel HD 25W-60 API CF-4

Technical characteristics

• Type: Mineral oil for heavy-duty diesel engines.

• Viscosity grade: SAE 25W-60.

• High viscosity for high mileage: Designed to compensate for wear in engines with high mileage or operating hours, helping to seal mechanical clearances and reduce excessive oil consumption.

• Anti-wear protection: Forms a thick lubricating film that protects internal parts against friction and wear under severe loads.

• Thermal and oxidation stability: Resists degradation due to temperature and combats the formation of sludge, varnish, and deposits.

• Compression restoration: Helps improve cylinder compression and reduces lubricant leaks through aged seals and gaskets.

Classifications, specifications, and approvals

• International specifications (Meets the requirements of):

  • API CF-4 / CF / SG

Applications

• Older generation heavy-duty diesel engines with high mileage or increased accumulated wear.

• Cargo trucks, buses, dump trucks, and heavy commercial vehicles.

• Agricultural, construction, and industrial machinery operating under continuous high-demand conditions.

• Diesel units operating in warm climate regions or subjected to high operating temperatures.

Usage recommendation

• Consult the manufacturer's recommendations or a mechanical specialist to confirm that SAE 25W-60 viscosity is suitable for the engine's condition.

• Replace the oil filter with each lubricant change to maintain the effectiveness of its additives.

• Keep containers tightly closed in dry, cool areas, protected from the elements and direct sunlight.
