It won't do anything for your truck that a lower cost synthetic won't also do. And it WON'T increase your hp. If you want a synthetic, use Mobil 1 5W-30. A lot of the claims made for products hyped on the car and truck shows are pure b.s.
I am pretty much sticking with royal purple. Everyone has their reasons for what oil they use. The cheaper full synthetics I've used- Pennzoil platinum and castrol- both burned a qt or more between oil changes. Mobile 1 and Royal purple both held their qty between oil changes. Why is this? I have no idea. It could be something else entirely.
