                Hi
                        I always use Mobil-1 with my car, S4, but it is
harder and harder 
                to find a shop that sell Mobil-1 lately.
                        Because of its lack of availability, I would like to
switch to 
                another brand. What do you recommend ? 
                
                        These are what easy to find in my country
                1. Esso Ultron
                2. Havoline
                3. Shell's synthetic, not remember the name.

                                                        thanks in advance
                                                        K.Ben
