It's a bit cleaner than the GC, that I shouldn't be using in my Town Car, looks at the same mileage. It might just be the flash. This could be the next oil that I shouldn't put into my car. Of course in a couple hundred thousand miles, I may regret not using the oil spec'd for it. Especially when you factor the extra twenty dollars in fuel costs, into the equation, over the life of the vehicle.
According to the Heisenberg uncertainty principle wear declines as viscosity increases. Yet simultaneously, nobody in the United States knows why the Europeans prefer thicker motor oil formulations.
