quote:Santo, let me take a stab at this one. I think no one uses them because there's no need to use them. Mineral/dino Straight 30 is one tough oil if you need a tough oil. And it is cheap to boot. Using a synthetic straight 30 is like overkill. Those people demanding the best protection for the summer, and eager to pay a premium for it, can choose from a whole slew of synthetic xW-50's out there.

If there was a straight 30 group IV/V that stopped at CF-4, I'd be using it.
