Store with dino and drive with Mobil 1. Change it half way through summer (Mobil 1) and then put to bed with fresh dino. It's even possible one change only with Mobil 1 depends how much short tripping and how hard you run it. If you can afford it and plan on keeping it 10+ years, keep the oil clean. re-read posts, ah yes keep doing what your doing. Besides, if you feel better about using Mobil 1, do it. It's worth it to me!
