I noticed yesterday that Pennzoil dino 5W-20 does not call out the Ford spec on the back of the bottle while Pennzoil Blend 5W-20 ("SUV, etc.") does. This makes me very leary of using the Pennzoil dino 5W-20.quote:
Ford and Honda spec 5W-20 oils then it would not make sense for an oil company to make a 5W-20 that could not meet Ford's tougher specs
Castrol GTX 5W-20 dino does call out the Ford spec on the bottle. Maybe it is really a blend.
