I went to get my oil changed and bought 5 qtrs. Mobil 1 75000 mile full synthetic oil, and a quart of extended performance synthetic oil. I thought that I could have the best of both worlds, but the technician told me they aren't allowed to mix oil types, which I can understand but also stated that mixing different oils can destroy your engine. I was wondering if anyone knows the facts about this and whether the technician was right. I can understand mixing different SAE ratings or mixing synthetic and non-synthetic oils, but mixing two of the same brand, same SAE rating oils that just have different additives? Any info would be helpful and appreciated.
Also, a little off topic, I have a 2014 ram 1500, 5.7L. I strictly use Mobil 1 full synthetic brand engine oil. Are there any better brands? Or rather, is there really any difference between Mobil 1, Valvoline, Pennzoil etc.?
Thanks!
