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.
