Modern trucks use new technologies to make as much as 30% higher torque, but this also means higher engine temperatures and pressures. This punishes the oil, pushing it closer to breakdown, and reducing its useful life and ability to extend drains. GP DEOGEN SYNTHETIC 5W30 CK-4 has been proven to safely extend drain intervals. Formulated with up to 45% extra performance reserve, System Pro technology fights oil breakdown by:
Combating oxidation and deposits.
Neutralizing harmful acids.
Controlling oil aeration.
Adapting to increased temperatures, resisting viscosity loss through shear.

GP DEOGEN SYNTHETIC 5W-30 CK-4 delivers proven cold start benefits to help prevent engine damage, reduce no-starts, improve battery & starter life.
