[QUOTE="Jeremiad, post: 106194, member: 3108"] I don't even know if I want to post a reply to this thread for the heartache that it may recount, but experience and hard-earned knowledge is better than blatant ignorance. It pains me to even think about some of the foolish decisions that are made over engine oil, but please let me assure you, the wrong choice is a costly mistake. The question of what oil to use in your car is a very important subject. A lot of people might like to argue it, and it has even been touched a bit in this thread even. I don't want to start any bullshit arguments in this thread, but the one thing that I will argue is that your choice of oil is imperative to your engine's survival. It is literally the blood of your engine's heart. When it fails.... damage happens fast. Do some research, and make your choices wisely. The links posted above have some good information if you have the patience and interest to read them. If you only ever drive your car on tours and cruises on nice days in the summer, then you will probably be just fine with the recommended Mobil 1 5W-30 full synthetic. I've never tried Dexos and will not. There is plenty of info out there to show that it does not stand up to the same levels as the Mobil 1. The purpose of this thread was to ask between these two oils, so this is just another opinion to consider, but please do pay attention to the other information here. The links above, and your own research, as well as other peoples' experiences. With that in mind, I have also experienced catastrophic failure due to oiling issues while using Mobil 1 5W-30 full synthetic, so don't think that it is a miracle fluid either. Knowing what oil to use and when can be a complicated issue. There are also at least a couple of other oils that I am aware of that are formulated specifically for LSx engines, such as Brad Penn and Joe Gibbs, both of which are endorsed by GM although I don't know if they are supported by warranty specifications, and I highly doubt that a GM dealer will even stock them let alone use them without additional cost.
