Picked some up yesterday because it was on sale and plan to use it next oil change coming up soon in place of Pennzoil Ultra 0W-40. Not much talk about GC 0W-40 around here so I just figured I'd ask what everyone thinks, is it any good? It's made in Germany so I assume it's probably a "true" synthetic over the American made Edge? Can it handle a 7500 mile OCI in a Toyota 5VZ-FE V6 paired with a FRAM Ultra filter? Isn't the GC 0W-30 being phased out in favor of this stuff too I thought I read awhile back?
