Review on Royal Purple Max Gear Synthetic 75W140 by Louis Mechtak

All my 6 arrived quickly in the factory box, in a different box. Mine were packed very well. This material is not the cheapest but works well. It is already mixed in with a friction additive and runs vibration-free most of the time without the addition of a friction modifier. However, if it jiggles, you can just add a tube of modifier and it will blend in nicely with it.
