High Zinc Mineral 25W-60 Street and Track Engine Oil (ST25W60)

Nulon High Zinc Mineral 25W-60 Street & Track Engine Oil is recommended for all large tolerance and high performance 4, 6 and 8 cylinder engines where maximum oil pressure and oil film strength are required.

Nulon High Zinc Mineral 25W-60 Street & Track Engine Oil is the chosen oil of multiple racing teams as it provides the ultimate engine protection during competition and the high-stress conditions found in drag, circuit and 4x4 racing.

Nulon High Zinc Mineral 25W-60 Street & Track Engine Oil has added Molybdenum Dithiocarbamate (Moly DTC) and extra levels of Zinc (ZDDP) to give you additional high-level wear protection and performance. Moly DTC is proven to dramatically reduce friction and provide increased engine wear protection from cold start to extreme temperatures, giving you added benefits over standard engine oil alone.
