I have been using Mystik in a Caterpillar engine for over 10 yrs. I had never heard of the other 2 brands until I inquired about the 5w20 synthetic in Mystik. There is a synthetic blend readily available in Mystik though. I did read ENI is used in the Lambos and Ferraris. Perhaps I am over thinking the situation. I just like to stay with a certain oil throughout ownership of the vehicle. In this case, we intend to keep this LR4 until its wheels fall off. Many thanks.
