My car has 6000 miles and I am ready to change the
oil to Mobile 1, I live in San Jose, Ca so what type of weight should I use : 15-30 or 20-50
After searching I see folks using Motorcraft FL1 HP / Mobile 1 / and Wix, can you get this in local auto store?
BTW, Engine made by CHP 427W
Please advice
Thanks
Tan
