Autozone is currently giving all of its employees a just of nexgen or maxlife nexgen. I picked up a bottle of the regular stuff. I have been running Mobil 1 / Pennzoil Platinum / Pennzoil Ultra Platinum in my care since I've owned it (40k miles). The smell of this nexgen is rank. Makes me gag just smelling it, so it makes me weary of running it in my engine. Should I do a short 3k OCL or just dump it in the mowers?
