I don't think that your right. Prove it to me and I will believe you. Castrol oil is better than Mobil 1 in my opinion.
One thought although possibly more economically persuaded. 1 qt of mobil one goes for 8 bucks and 1 quart of castrol goes for 4? Does the castrol say fully synthetic or does it say synthetic?
Im not really trying to prove anything, i just wanted to get the word out about a good deal on what IMHO is my prefered oil.
