This engine was specifically designed for 5W-20, and a particular formulation of 5W-20 as well. Don't use any other viscosity unless you're willing to deal with the possible consequences...5w-20 is an odd oil in a day and age where 0w-40 is readily available. is there any rational as to why 5w 20 might be better? 0 is better at startup and 40 is better at operating temps
The oil is used to control the variable valve timing, and variable valve lift, in the AJ133 V8 engine in our 2010-2013 LR4's. Different viscosities could affect operation of these systems. If the engine was designed for a particular oil viscosity and no other viscosity is approved, don't try to out-think the engineers.to be honest i dont buy that an engine was designed for a certain oil...its a bunch of moving metal parts - what wld 0w40 impact?
