I am doing another cam swap now from a very mild cam to the more aggressive Night Fury. I will be using Lethals package including high flow Melling. I have been using Mobil 1 since my first swap. I am interested in seeing if the old cam shows any abnormal wear. At this point I think I will change oil brand. Who knows. All said, seems like rolling the dice with any choice. Hell, I'm paranoid at this point to start the car. I'm going to run it in the ditch watching the oil pressure gauge!
Lethal uses Mobil 1, and I did before the night fury cam install. But after my own research, I switched to Amsoil. Theres really no reason not to, Amsoil or other premium oils are, without a doubt, better. Not voodoo or anything.
Yes it costs more, but it lasts longer.
