Personally I use Red Line in the Murican cars, and most of the other cars get Rotella T6.

Weight is all dependant on what you set up your bearing clearances to be depending on your application..... I wouldn't get to worried about what brand of oil your running, to much internet hype... when's the last time you heard someone say I wish I had of used Lucas instead of shell.

I use Brad Penn Grade 1 in my chevelle because of the increased levels of zinc, its made in the USA, and its affordable.

I have used royal purp in the past... read so many bad things... i stopped and everything we have gets mobile one. (fyi.. procharged ..385...lt1 here)

LTXtech.com is my DRUG!

i run Rotella t6 because it's good oil and is cheap. i've been contemplating the switch to Amsoil though, my car only gets one oil change a year so the cost difference wouldn't be all that bad.

15-40 Rotella, cuz my builder said so.

All depends what your builder says to use, he is the one that spec'd the bearing tolerances.
