By brand I will say Lucas, I have seen that oil keep bearings spinning that were completly shot. If I had the money all of the fluids in my bronco, crewcab, rv would be from lucas.
It also depends on what your putting them into. Liz's stealth needs full synthetic, where my bronco didnt like it when I put it in the engine. The jap motors are made to use it, my eb motor is based on the Shelby 289 and for some reason it just didnt agree with full synthetic.
Overall I would stick with name brands that have proven them selves, Lucas, mobil 1, valvoline.
Just my 2c.
