The VQ engine and aluminium thermal load
The VQ35 and VQ37 are aluminium V6 engines that run at high revs and therefore shed more heat. Georgian conditions, with constant gradients, 35 °C summers and heavy traffic, add to that load.
In the hot-surface corrosion test (ASTM D4340), which targets the hottest point on an aluminium surface, Zerex Asian Blue returned 0.1 mg/cm²/week against an allowed limit of 1.0.
