First, yes I have searched and I know this topic has been beaten to death, but I still can't find a good answer as I think it all depends. So my question is which oil should I use for MY car? I just purchased it and need to change the oil. I don't know what the PO used, but I can see a purrolator oil filter so my guess is whatever Midas put in it. I live in Colorado, currently has about 150k on the engine, car is only going to be driven in nice weather (my guess on temps would be between 40-100), this isn't my daily so it may sit for a while at a time and I have a lead foot. I'm leaning towards Castrol 10w40 non syn. Thoughts?
Thanks
