If you are using Mobil1 Supersyn (gold bottle I assume), then adding Nulon additives to it would be a downgrade! If you had some cheap oil like MTF, Magnatec or the Mobil Synth S, then yeah, it would be worth adding Nulon. But if you already have Mobil 1 Supersyn, then it's like adding tomato sauce to some high class food that tastes so good that you get an orgasm with each bite. You get what I mean?
