This is from an article in the July issue of SAE International. This is not a commercial. Keep in mind that Pennzoil is owned by Shell.

so how much does this stuff cost? 15 bucks a quart. usin mobil one now so cant be much more, lol

 

Nice article, but I'll put money on it that those are doctored photos. Look at the rods, both of them have the identical stain/shadow markings. That alone would be impossible. And on the pistons, you can see the moon shape mark on the right one that matches the same shape on the left one, right down to the "notch" on the top part of the stain. Again, impossible to be that identical. Phony phony phony! Gee, do companies really do that kind of thing purposely to sell their product? Naaaaaah, that would be dishonest.

 

They probably used the only perfect engine in the universe, but a good air brush artist is more likely. lol
